What's the best LPG conversion system suited for TJ 3.5L Auto Sedan, and how much do they cost (budget under $2.5k)?

I got quoted LPG conversion using Impco equipment and a 68 Litre tank in the boot for $2,495. I am just wondering if anyone has this brand of equipment can give me a feedback, and is the price reasonable?

I heard there are some LPG conversion equipment that causes frequent stall to the engine. Which equipment are they (so I can avoid it)?

Hey mate.

Sounds like you were quoted for a 'Mixer' style gas system for that $$.

The mixer system is '70's technology. Its like putting a carby back on your new car.

The best gas systems are called SVI systems which is where each cylinder gets its own gas injector, just like petrol fuel injection but gas instead.
If you get a mixer system, there is always the chance of stalling/rough running/poor performance/hard to tune for both gas and petrol.
If you can afford a SVI system 'usually around the $4000 to $4500 mark', you wont even know your car is on gas. It will run perfectly, no loss in power,no rough running/stalling.
Then you have the cas tank option. there are 2 types. In the boot like you are talking about which hold approx 68L and then you can get the donught tank approx 60L which goes where your spare wheel is which means ou don't even see a gas tank at all. Much better option but costs more.

Go the gas social page mate for more info and pics.

I probably don't want to spend $4000 on it, in case some idiot write off my car, I would lost everything as magna doesn't worth much on the market. What's the best available under $2500?

mate i got a mixer on mine and very happy it works good not a lot of difference from gas to petrol
the main thing i got told is you can lose up to 20% power on gas well i can take anyone for a drive and they will not know the diffrence
as well in qld i know they have the rebate 2000 back i got mine just over a year ago for 2700 and got 2000 back so cost me 700

Do you mind to post pic to show how they fit the switch in the dash and the refuel opening?

aye..i too have mine on the mixer system...simply so i couldnt touch/modify the engine for my licence's sake.

Quite happy really because it cheap as chips to run. The switch i got was a tiny push button on the left hand side of the dash beside the steering wheel, barely noticeable. Yes theres powerloss but if you dont really care for speed and power then there no probs there. Mine set me back $2299 so $299 after the rebate.

Go to the comunity menu up top mate then select social groups, then look for the gas pages. Heaps of pics there.

You could always go the SVI system and if your car is in an accident(doubtful) then rip it out before they take it away.

I assume with the predicted power loss, it is still stronger than a medium car, (eg: corolla/lancer) correct?

The best quote I got is 2495 from lpgas1.com.au at Marrickville, Sydney. Has anyone converted with this company?

Please advise... planning to convert within 2 weeks.

Oh the powerloss will not turn your magna into a toyota echo mate! lol You can tow to capacity and what not..its just really the peak power that you lose, and if you are constantly gunning the throttle then you will notice.
I used Ezigas to convert simply because id heard really good reviews of them and they do a bang up job!

This thread here should provide you with some interesting reading material.

My advice is that if you want reliability and virtually no power loss then get a SVI system. Bite the bullet and spend the extra. The reliability will pay for itself in no time. I have had bad experiences with my stepfathers TJ that has a vapour ring system. Backfires, blown AFM's, sluggish, poor economy, chewing plugs... Should i go on? lol

The SVI system i have fitted has been faultless bar a tuning issue which was fixed in less than 5 mins with a firmware upgrade and an injector block that was replaced under warranty within the first month. It gets 630kms on the highway out of 67 litres and has only a slight power drop compared to ULP.

Thanks for the thread reference.

Is there much further fuel efficiency gained from a SVI system over the Impco system to pay for itself off over time? Is this the manufacturer of a SVI system: http://www.parnell.com.au ?

It doesn't seem a 2000 TJ is in this list (http://www.parnell.com.au/index.php?option=com_content&task=view&id=44&Itemid=63)?

Is the Impco system a vapour ring system? I am totally new to this so different points of view are welcome.

Any leads as to who is best and less installer in Sydney on such system?

LPGAS1 are a good reputable company mate. Can't comment on that branch in particular but they have a good name along with EZYGAS.

Impco is the brand of gas system. I'm guessing it is a mixer(old style) system.

And yes, you get much much better economy out of a SVI system over a Mixer system.

As Type 40 said, if it is possible, spend the extra. Trouble free motoring with an SVI. Mixer, there is always the possibility of trouble/unreiability.

I put a Eurogas SVI system in my AWD. It is faultless. I have no power loss at all over petrol. It actually has more low down torque on gas than petrol.
It cost me $5000 with a donut tank, i got 2000 back from govt so was out of pocket $3000. It paid for itself in about 10 months of driving. Now i spend $20 aweek on gas rather than $80+ on petrol and i can drive it hard without worrying about the cost.

Here's a 2nd hand factory LPG system for sale (http://www.aussiemagna.com/forums/showthread.php?t=70325) for $150!

So is it a choice between Eurogas and Parnell?

I had just shoot an email asking for quote to eurogas, but can't find one for parnell...

Anyone know how well does JTG liquid injection work?

I got quoted $2500 on a Lanvi Renzo system, and $2600 on a Airod system. Anyone familiar with this brand can comment? Both installers said this type of car not worth to spend extra on a VSI system.

Its not the installer's place to decide if your car is worth getting SVI or not. If they pulled that crap on me I would've let them have it.

After spending a lot of time researching, there's no clear answer as to which vapour ring system is the best. Since Mitsubishi uses Impco to factory install LPG, I have decided to go with it. I acknowledged some owners has backfiring problem with this system, equally, there are a lot that has no issues. So I guess it's all depends on the installer's skills.

As for VSI system, a lot of references online suggest that there is little benefit gained from an old pre 2003 car. Given the car is worth around $5000 now, it doesn't make sense to spend an extra $1500 in it. As long as worst case power loss is still stronger than a medium car like a corolla, I can live with that since I drive quite conservatively.

Cheers

I'm fairly sure liquid injection isnt avaliable for magna's yet.

Who would suggest that a SVI system or liquid injection system isn't worth it? Are they stupid?

I can't believe that they even still make mixer systems. As said before, its like getting your Magna, ripping the fuel injection out and putting an old 1st gen carby back on it. Thats what you are doing if oyu go a mixer system.(not literally)

Who cares what your car is worth mate. If you intend on keeping it for a long time, (more than a few years) then go the SVI system and give you more power/reliability/lower servicing costs/peace of mind when driving.

As for brands, Eurogas are known as being one of the better/best SVI systems on the market.

I probably keep it minimum 1.5 years to pay it off to even up, quite possibly upto 8 years. I drive roughly 15,000km/yr, 120000km over 8 years.

As for financial maths:
Vapour ring: 17L/100km, 70c/L gives $14280 + $745 gap = $15025.
Vsi: 15L/100km, 70c/L gives $12600 + $2250 gap = $14850.
Petrol: 14L/100km, 1.30/L gives $21840

As for servicing cost, I was told vapour ring system serviced every 20k at around $120 and every 60k at around $220. What's the service intervals/cost like on the svi system?

They want to see the car every 10K for a service but literly dude, they do nothing. They just check for leaks. Thats all. If you had a leak, you would smell it.

SVI system is literally maintenance free(another +tive). There is no manual adjustments like a mixer system. Its all done electronically via its own ECU. Just the same as your car's.

Its up to you dude, but seriously, if you are thinking of keeping it for possiblky 8 years then i wouldnt't even cosider a mixer system.

I just dont trust the unreliability of them.
I have been in one with a mixer before, was turning out of a T intersetion, floored it and BANG, air box blown off, car stalls and im stuck in the intersection. NO WAY would i have my wife and kids in a car that could possibly do that.

And those consumption figures are just approx. an SVI system would beuch much more efficient than a mixer system.

Either LPGAS1 or EZYGAS will do a good job and will quote you for an SVI system. Ezygas will prob use a sprintgas system which are also a great system. Just ask TYPE 40.

I haven't had much luck with quotes on the SVI system. All installers just talk me out of it saying it is not worth it. If anyone has a latest pricing, feel free to post.

Where have you got your figures from? The SVi system will not use only 1l/100 less than the vapour ring system. Try 2-3l/100 less.

I have both - a vapour ring in a TL FWD, (15l/100) & a SVI system on a KJ AWD, (12.5l/100). This is both cars doing the same trip - to work & back - the TL for a year before I got the AWD. Now, seeing as the AWD uses more fuel anyway, it realistically puts the usage as around 10 or 11l/100 for the SVI system in a FWD. (There are members here who claim to get close to 10l/100 in their FWD's). I'd redo your calculations for you to show you the extra savings but I can't work out what you did to get to your end figures.

Most systems will come with a 2 year/ 50,000km warranty - if they don't, steer clear. Don't listen to the installers, you're the customer - they just don't want to do the SVI system as they'll have to 'work' for their money. (ie, remove inlet manifold, drill holes, tune etc). You wouldn't go to buy a pair of jeans & come home with a dress for yourself, would you, just because the retailer talked you into it, now would you? :happy:

I have a vapour mixer system. Manchester tank, Airrod convertor, Tartarini controller. Had it for well over a year with no major problems. It has just about halved our fuel costs. There is some drop in power but this being my first 6 cylinder car in 25 years it runs better on gas than any 4 banger I've had. no backfires or any other issues to date. It does sometime stall when going from petrol to gas. I have to remember to give it a little rev to prevent this.
Cost $3300 to install with a final $800 out of pocket. At the time the sequential unit was going to be $2700 out of pocket.

Finally got a quote for the Eurogas system for $4000.

I am wondering how much is the equipment alone worth?

If the car dies, would the equipment be easily transferred onto another Magna?

I am wondering what else to look for regarding Eurogas quotes. Do I assume all parts are Eurogas, or will some parts be some other brand that I should watch out for?

That price sounds right for a Eurogas system.
That would be for a tank in the boot behind seats. If you want a donut tk in spare wheel then add another $800odd.

Eurogas is known as one of the better/best systems on the market.

The euro componentry will be, the converter, injectors and ecu. The rest(tank etc..) will probably be sprintgas or someone else.

You sure can take it out when/if you have an accident. You would take the converter, injectors, ecu and the tank. You wouldn't bother with the gas lines/plumming etc. That stuff isnt dear anyway.

Isnt really that hard to remove all that stuff if you had to get it out quickly.

Easy enough to do. I did this after I wrote off my least AWD.

Where can the spare wheel sit (in a sedan) if it were to go into the spare wheel compartment?
I assume this (http://www.australianlpgwarehouse.com.au/Kits/Mitsubishi/Mitsubishi-Magna---K-MI-MAG9305S61.aspx) is the kit for all Magnas from TH era onwards before 380 takes over?

You dont carry a spare wheel mate.

They ususally give you a can of tyre repair foam and a compressor. If not, you can go buy your own cheaply from Supercheap.

If you do get an unrepairable flat then you just call a tow truck.

When did you last have a flat?

I dont think i've had one oin over 15 years.

I'm not sure if thats what i have but if you get it done at either LPGAS1 or EZYGAS they will install the correct system.

Just don't go to Karajini National Park in the Pilbara - we got 3 punctures in 20km! I could fix two on the spot with my puncture repair kit (http://www.discountcaraccessories.com.au/store/products/Tyrepliers-Puncture-Repair-Kit-%252d-FREE-SHIPPING.html), but not the third...

Driving 400 km out there with no functional spare was not fun... carrying (or not carrying) a spare depends on the type of driving you do.

Isn't carrying a spare a mandatory requirement for the car to be roadworthy?

Isn't carrying a spare a mandatory requirement for the car to be roadworthy?

In Victoria if you have a spare in the car it needs to be in roadworthy condition but you are also allowed not to carry a spare. Some cars are sold new without spare tyres. BMW 3 series springs to mind.

But the BMW's are fitted with RunFlat tyres (http://www.bridgestone.com.au/tyres/technologies/rft/default.aspx)though, and ride quality is somewhat comprimised. Good video though.

Yeah i know that! Thats why they dont have a spare fitted!

I was asking the same question when i was getting the donut tank and everything was pointing to it being legal/roadworthy NOT having a spare tyre as long as you have the tyre repair kit/weld and a compressor.

Well, I've paid a deposit today, but I felt somewhat cheated. Asked for an Eurogas system to quote, agreed to $4000 price, paid a non-refundable deposit, only to learn afterwards that it is an Emer (http://www.emer.it/) system, which they say came from the same manufacturer. If I want an Eurogas branded system, I need to pay another $400 more. They said the term Eurogas is a generic emission term for cars made from ~2006 to meet some emission standard. Unfortunately, I got no written quote to base on so I felt I have to accept the Emer (http://www.emer.it/) system. :(

I'm sure it will be fine. Well done on going with an SVI system mate. You will not regret it. You will be amazed at how well it works and how rerliable it is. You wont even know its on LPGas.

WHo did you end up getting it installed through?

The company is called Auto Spot (http://www.lpgcarconversions.com.au). They are the cheapest quote I got for vsi, and looking up their ABN, they seems to be in business for nearly a decade, so I assume they know what they are doing.

I am just wondering, since my car isn't factory lpg compatible, what extra precaution I need to look at? Research online seems to suggest valve seat recession may wear out pre-maturely, some suggest engine head might crack due to high temperature. Any non-factory LPG compatible converted TJ owners can comment?

The say with SVI systems that the motors come fine with LPG. There are a lot of members on here with LPG with high milage with no iussues.

If you want peace of mind, you can put on a upper head lube system(flash lube). http://www.flashlube.com/en/index.html

This will help lubricate the valves. I have it on my AWD. Most say it isn't even necessary these days but its cheap insurance.

They should throw it in for nothing really but if they are going to charge you for it, don't let them charge more than $100.

Did you go a donut tank or standard tank behind seats?

Also, when you drop the car in, just push the issue that you want it as neat as possible to look like factory. SVI systems are fairly neat anyway but if you hound them about it then they will hopefully put in more of an effort.
Do you have a plastic engine cover on top? If so, tell them that it must stay on as some gas installers try and leave it off to make their job easier to fit the injectors etc.. It can easily be done to stay on.

Valve seat recession was more of an issue back in the days when we had "super" grade petrol. The valve seats in those engines were of a lower quality but had the lead content in the petrol to provide a cushion for the valve against the seat. Those engines did need to have the heads done for LPG as after a while you would either burn out valves or have valve recession. In unleaded engines the valve seats are of a higher quality and are are designed to operate with lead free fuels and leaner burn so LPG works perfectly fine in these engines. Mine has done 50,000 kms on gas with no issue at all.

I went for the one behind the seats because it seems better protected from rear end smash and feel safer for long distance road trips. I do have some worries about rust when they need to drill holes to attach into the chassis. They said they can't paint the drill affected area, but will install it with rubber.

I think it has a plastic cover. I'll double check on that. Any other advice/instructions to the installers? :)

About the only other thing you can tell them is where you want the lpg/petrol switch.

I wanted it as out of the way as possible as i dont want the car to look like it has gas.

I have it down near the gear shift leaver, but right up near/just under that ashtray that slides out if you get what i mean.
Some just want it on the dash near the dimmer. Its up to you mate, just tell them where you would like it.

Thats about all. Did you know you can get a carpet cover for the gas tank being the same carpet that your boot is lined with? Looks much better looking at the carpet cover than a silver gas tank. It is a factory moulded shape carpet to fit perfectly.

When does it go in?

I wouldnt be to worried about rust. Water doesnt really get up there. Everyone has those holes drilled, even when you get some tow bars put on, they do that so i wouldnt be concerned about it mate.

Hopefully it will go on soon. They said the stock are in Melbourne so I would guess it will take a few days to ship. If I were to elect the Airod mixer system, they would have been installed by now.

They had shown me where the switch/gauge will go.... on the harder plastic plate covering under the steering wheel. I assume I can still choose where to go within that hard plastic plate covering. They said it won't hook up to the car's trip computer.... something Impco has an advantage in this respect. Any pic of your switch by any chance?

Any idea of the carpet cover? Is it something I can buy from any auto store (eg. super cheap auto)?

Your trip computer will still work. Its just not as accurate, thats all.
I don't know why they say they wont work. They said the same to me but it still works as per normal. Its just the distance to empty that gets a littlke confused, thats all.

You can put the switch anywhere. I was even going to put it in the centre console under the lid but decided against it.

I will take a pic later on today for you.

As for the carpet cover, it is a genuine mitsubishi item. Someone on here has one. I will find out and let you know.

Here you go...i got this off a member here,dont know where you would get one,butt this gives you an idea what it looks like...i like it heaps.

..and depending on the switch they use..well,any way,my switch it a round black thing,and my car has traction control,and they put the switch down on the side under the mirror switch,but i swapped locations for the traction switch and put it in the dash,on the right side of the cluster....

Have you a part number mate?
Does it have it on the cover somewhere?

I've got factory (Impco, a mixer system I think) gas in my TW, and it causes as far as I can tell no loss of power, but by god it's thirsty. Around town about 18-19/100km.

It its a mixer it would definately have a bit of power loss.
Yeah the upside of SVI is better/more efficient fuel economy.

Hey mate.

Here is a pic of where my switch is.

It is under the cigarette lighter. The one next to it on the right is the mobile bluetooth.

Nice hand discrete. I did not want a big switch in my direct line of sight.
Makes the car look cheap in my opinion being able to see a gas switch on the dash.

Hey all,

My car went into the workshop this morning. I had checked the engine bay prior and found it has no plastic engine cover. Maybe they don't have that in the Executive base model.

Also, I asked them about the flash lube which they quoted extra $190 for the "system" and advised I do not need it. So I didn't end up getting it.

As for the switch/gauge unit, I think it's better to be in the panel under the steering wheel, just in case I want to rip apart the LPG system and transfer onto another Magna later down the track, the hole won't look too noticable.

Lets hope FamilyWagon is right about better fuel economy on the SVI system. Looking forward to get the car back end of tomorrow.

Cheers and thanks for all the helpful advice!

Good one mate.

Gas isn't quite as efficient as petrol but an SVI model is much much more efficient that a mixer style.

At the end of the day mate, you have made the right decision with a svi system for reliability/performance/economy/maintenance free operation.

You will be wrapped with it. Enjoy it.

You will love the $20 to fill rather than $70+ every week.

Since when does it cost $20 to fill a 60 litre LPG tank....what you get your gas for 30 cents per litre....even at 50 cent per litre ,its still 30 ish dollars....on average it cost me 35 to fill mine up.....

Sorry mate, i was talking about mine which i only usually put about 45-50 L in it when red light is on which at 46-48c per L cost me about $20 to 22.

And i only fill that once a week getting about 400k's around town which isnt bad for an AWD on gas.

OK, I am not very familiar with LPG pricing. Does it follow the same petrol pricing cycle, cheapest on tuesdays?

Nah mate,gas stays fairly static. Does vary a little sometimes but not usually in any cycle, where i live anyway.
It only usually goes up and down by around 2 to 3 cents so who really cares what its at.

Got the car back. Got a few problems. Can you guys lend me your advice:

1) There is a strong smell of LPG in the cabin throughout the 12km journey home. Is this normal right after the conversion?

2) The trip computer no longer work. Only toggles between "5" and "L J" and flashing. Not even the speed alarm works. I assume when they say the LPG system won't work with the trip computer, at least the speed alarm works. Am I right?

3) What's the knob at the tank for?

I am taking the car back to them tomorrow for the speed alarm/trip computer issue. So any helpful advice would be very much appreciated!

I have attempted to answer your questions! In bold.

I assume when they say the LPG system won't work with the trip computer, at least the speed alarm works. Am I right? My trip computer works spot on. Even the average and instant fuel consumption readings (although on LPG they are about 10% out) But has the trip computer been set up correctly since the battery has been disconnected? the "5" you mention is actually an "S". Refer to your owners manual for the correct way to set up the t/c.

3) What's the knob at the tank for? There is a knob to shut off the LPG. Is that the one you mean?

Yeah looks fine for an SVI system mate.

The smell isnt right. Every now and then you possibly may get a very slight smell of LPG but when your car is still and off, not running and especially not in the cabin.
They will fix it mate, dont stress. Mine did the same. Sometimes copper line joins settle with the car movement causing slight leaks. They wil leak test it and fix it.

The knob on the tank is just to take that cover off if ever needed. The emergency shut off valve is in there.

As for the trip computer, it should all work fine as normal. The instant fuel/average fuel/distance to empty isnt as accurate as when on petrol but it all should still work fine.

Thanks for the reply Type40 & FamilyWagon.

Guess they stuffed up the trip computer.

Not sure if LPG smell is present when car engine is off, but certainly there while driving.

Fingers cross that they will address all those issues tomorrow.

Dont worry mate, they will fix it in a second. Not a big issue.

The trip computer should come back online. They should be able to do it.

Forget to ask, how does she run?

Same as on petrol? Can you feel a difference if you switch between the two?

I guess you probably havent felt the change over fom cold yet but that should also be seamless. Usually on 1/4 on the temp guage.

Enjoy the cheap motoring.

Starting the engine seems smooth enough, but it's not a cold start. The engine was warm when I pick it up. Can only tell from tomorrow.

On the go, it seems alright. Not sure if it is on par with before. There seems to be a little loss in power when trying to accelerate from stationary. I need to drive a bit more to confirm this.

On stationary at the lights, the car seems to shake/vibrate a bit more than before. Is yours the same?

The shake may be just due to a lower idle.

Do you think its just a lower idle Shake? most likely is.

You can get them to put up the idle you want. They just plug in a laptop and do it. Get them to match it to the petrol idle.

Thats why you go back after 1000k's to sort out all these little issues once the system settles.

I think the idle is on par with petrol reading. Would higher idle give higher fuel consumption?

They didn't ask me to go back for a 1000k free service. The whole process with this company isn't too positive so far. The boss is not very friendly to talk to compare to other companies I obtained quotes from.

Nah, idle wont affect fuel consumption.

Just try it on petrol at a stand still and then gas and see what the idle is like. You can always play around with it.

Just picked up the car.

With regards to trip computer/speed alarm, why does it need to be reprogrammed and how do you do that? How come I never had to do that when swapping the battery over few years ago?

With regards to gas leak, they said there is no gas leak. When I pickup the car, initially I thought the problem is gone. While I drive home, I still notice a little bit of the smell. I think they will just say there is no gas leak if I take it back again. Any suggestion how I can get rid of this annoying problem? Where do you think the gas leak most likely be located?

Is very weird that when ever I sent my car for a Gas service check it WILL STALL the next day when I am driving. but after that is ok.

with the trip computer press the 'mode' button until it says 'S' for sedan (looks like 5) and then hold down the mode button until it beeps, then press mode again until it says 3.5l, then hold down mode until it beeps again and you should be good to go...

just a thought, if the idle is rough, could it be that because the battery was disconnected, you may need to do the auto re-learn procedure?

Good point annese.

As for gas leak, it should not smell like gas in your car at all. You should rarely if ever smell gas at all and never in the cabin. Take it back and tell them you can smell gas inside the car and you dont want it back until its fixed.

I can see this is going to be a real pain in the butt.

The gas smell this morning upon getting into the car is less intense than yesterday morning. By the time I got to my office, it's hardly detectable. I just gave them a call and they don't seem to believe me, but reluctantly ask me to go back on monday. I just hope the smell will still be there by the time it gets there, or it will be a never ending problem... Is there any ways I can hold the smell within the cabin without gassing myself?

Well just keep the windoes up and on re-cycle.
Hopefully the smell goes which means problem solved.
The eumonia in gas which smells is very strong. Wouldnt worry about gassing yourself. It only takes the smallest amount of gas to give off that smell, so if there was a big leak, you would be choking on the smell.
Hows the car running in general other than that?
Change from petrol to gas good? What temp does it do it on your temp guage?
Is the idle still a little rough? f so, maybe get them to put it up very slightly and see if that helps.

The car is running quite well. I didn't notice much difference in performance compare with petrol. The switch over from petrol to gas on a cold start is roughly in 3 minutes time at about 1/8th the temp gauge. Idle vibrates a bit more than petrol, but it's barely noticeable and is still tolerable. Guess safer to leave it. More fix, more chance for new problems to be fixed...

First refuel shows 14.38L after clocking 60.35km. That's 23.82L/100km. Must be a leak to give this reading?

Hey mate.
Your slight leak you may have wont cause any difference in your fuel consumption. Trust me, if you had a serious leak, you would not be able to breathe in/around your car from the gas.
The leak would be small, the gas leaking out would be so small you could not measure it.

As for fuel consumption, fill it up till it stops, reset trip comp, then next time you fill up, fill again till it clicks and get your K's done and work it out manually, not through trip computer.

Also, the amount of gas a gas tank will hold varies a lot depending on a few factors such as, angle car is on when filling and air temp outside so dont take that too seriously.

I am extremely confused about the installation so far. I really can't explain it... or say if there is really a problem with it.

1) The gas smell in the cabin seems to gradually go weaker as days goes by. It is still barely noticeable when the doors are open after parked for a long while, but it will be almost gone by the time you driven the car. Why it does that? I can't really tell if it is due to my body got used to the smell?

2) The gas consumption in the last fill up was a shocking 23.82L/100km. Tonight, I clocked around 108km and filled up 13.xxL till the machine stopped (that's roughly 13L/100km). Last 2 fill ups also filled till the machine stopped. Why the result differ so much? I didn't think the few factors mentioned warrant such big difference.

I got the k's reading through the k's counter located right below the odometer, not through the trip computer.

Seriously mate, the quantity you can put into the tank can vary by upto 10L depending on slope/weather etc.
Just drive it like uyou did before and compare how much you now spend xompared to before. I guarante you will be happy.
I just filled up my KH today at $78 for the first time in a long time. Holy cow, im not use to that sort of $$. I only usually put $22odd a week in the AWD on gas.
We would be spending that $75+ a week in the AWD if it wasnt on gas.

He has already converted the car...

Current average I got is around 6.5km/L of gas. Mind if I ask what are your averages?

I work off L/100. Currently i do about 11 on the highway and 12 around town.

That would be around 15.4L/100km. Hmm... something is wrong.

Mine is injected remember. They are naturally a bit more efficient... But i think your consumption does sound a little high.

Here are some LPG useage figures from current/previous family vehicles:

TL AWD ezygas SVI system = 11.9 - 12.4 ltrs 100km highway & city
TJ2 exec auto wagon SVI system = 10.1 ltrs 100km highway
TJ2 exec auto sedan factory dedicated Impco air valve mixer system = 11.5 - 12.2ltrs 100 km highway & city
TW ES auto sedan factory dedicated Impco air valve mixer system = 9.5 - 12.5ltrs 100km highway & city (written off Jan 09)

You mean vapour or liquid injected? I believe mine is vapour injected... and figure is for city driving. Maybe I'll ask them to tune it on my next service if it's that bad...

BTW, with regards to service, do I now have to take the car to an authorised gas installer for service to prevent muck up of the gas installation?

Mine is vapour injected... By your mileage i think that there is something definitely wrong. Maybe it needs its tune tweaked to run it leaner (that is if it is rich). When mine was first fitted it was given some generic tune that was extremely rich (into the 10's and 11's) but all that did was mainly kill the power. Since then the LPG ECU has been dyno tuned and leaned off considerably which has given me better power and economy. I'm getting 630 kms to a tank on the highway before it runs out. So that's 67ish litres. Maybe have a look about for someone who can dyno tune your LPG system for the best effect?

You sure that's right? Most AWD owners can barely get their petrol consumption figures that low.

If Type40's getting 11l/100km in his FWD.....

My AWD's similar to your's for city, but ~12l/100k for highway.

Hey Al.

My AWD does 9.1 all day on a hwy an petrol and i get about 500k's nearly exactly out of 53 to 55l(full tank) on gas.

Remember, my gas has been custom dyno tuned as well where as the gas ecu when installed is a generic tune.

Hey guys sorry if this is out of place, but having the mixer on the car - i figure is like as people say having a carbi on the magna. When you do have a carbi on a car, the carb is always situated in the CENTER of the intake manifold that way each cylinder gets a equal amount of fuel. Not liek the car knows whether it is sucking in gas or AIR - so its very important to get the right amount of gas to each cylinder not alot of gas and low air in one and heaps of air and low gas in the other... The way it is built with Fuel injection manifolds the throttle body is at the right hand side, so the first cylinder would be geting alot less gas/diff ratio to any other cylinder... I was wondering if a Aftermarket/custom Intake manifold with internal ram tubes to equalise pressure would make a difference here... OR if instead of having the pipe of gas going to the throttle body, having it separated into 3 tubes fitted onto the intake manifold (on the large pipe that all the tubes feed off) that way the gas would be more equal between cyclinders and also instead of using the throttle body to suck fuel - sharing fuel with the air intake, sacrificing the ammount of air that is able to be sucked in, less air less power, less mileage.

so would the custom manifold make a diff? or the idea of puting 3 or so pipes connected to the intake manifold rather than the throttle body... ?

if this is irrelevant to this thread let me know, i dont mean to disrupt anything on this thread just seemed like the most appropriate thread :)

Thanks :)

Hey mate.

The only reason we say its like having a carby on a car is because of the old technology and how it works.

Would highly doubt it would make any difference in changing the setup. Not worth it.

If you want more power then go to an SVI system if money permits.

:)
hey got a quote for LIQUID INJECTION on a magna - ur looking at $4800 :) went on teh net looked up the liquid inject website and found a installer near penrith nsw :)
:)

How much more efficient is liquid injection?

Edit: Whoops only read the date of the above post, bit of a thread revival LOL

I've got a TW auto with factory (Impco) dual fuel. Driven gently, with the gas, and everything else, serviced regularly, it gets 19l/100km. 12.5 on petrol. Around town. I called Impco and asked them how much more than petrol this system should use, they said 22%. Mine uses about 50% more, which they said is way too much. I've taken it Southern Autogas, who claim they fitted all the factory systems, and they said it was fine.

So I took it today to a local (Impco-recommended) LPG place, and they took one look at it and said, "wow, that's old technology, and there's nothing you can adjust on that; we fit Impco, but not Impco systems as primitive as that". But they recommended I take it to Abba, in SOmerton Pk, SA, so it's going there next week.

Moral of the story:

1. Not all Impco is the same.
2. Do lots of research.

But I must say, my system drives v well, never has a backfire, never gives any trouble.

I'm thinking about buying this TL AWD on LPG.

Can anyone identify what type(not necessarily what brand) of conversion this is?

Pluses/Minuses?

Looks like a vapour ring setup ie: vapour ring mounted in the air intake adjacent to the throttle body & no sign of an SVI system ECU mounted anywhere in the engine bay.

Cheers

That's definitely a ring mixer setup. I have one on my TH Magna. Works very well, plenty of power. My AWD GTVI has a vapour injection setup. More fiddly to tune, gets good mileage.
