Went back to S.K.R. for a couple of runs on the dyno to determine the real torque figures.
Some dynos can do this.
Steve could'nt help himself and did a re-flash which gained another 2 kw.
So it ends up its gone from 93.1 kw to 123.9kw.and the torque figures on this chart are real.

Thought this little beauty may be of interest. 330+kw.

Nice figure!,so are you still pleased with the feel of the car?,hows consumption etc?

Im trying to find time to get mine done soon

Cheers

Yes mate very happy with it. Fuel is 11.5 and was 12.2

Was a 2.2kw gain worth a 12.8nm drop?

I presume so, but I'm no expert.

why 3rd gear?

why 3rd gear?

AWD is 5spd auto, 3rd is 1.42:1, 4th is 1:1. :think: But, was the car actually in 3rd or 4th, regardless of the printout. I have a printout that shows my AWD has 8 cylinders. Steve & Dave know what they're doing, trust me. But well spotted. Photochop time ;)

Was a 2.2kw gain worth a 12.8nm drop?

I'd have stuck with the 1st tune too. More mid range where the AWD needs it. But dynos don't always tell the whole story.

From a tuning perspective, there's no reason given the stock car that the 2 power curves couldn't be amalgamated to retain the best of both tunes. It's not like the cams were advanced on the 1st run then retarded on the 2nd. Just better mixtures and lots more ignition advance with the 98ron.

Any plans for a 3rd tune?

My Butto-meter can't detect any difference, so I'll leave it in the hands of the gods for now.
I've had an engine build offer I'm finding hard to resist,so more than happy with my 'stocky' for now.

So this is the guy that can re-flash the factory ROM?

Nice result as well :)

WOW :shock: :shock: Thats an awesome result very impressive !! Out of curiosity this re-flash must be very expensive yeah ? Seems to be a much better option than a piggy back style system, Sounds like S.K.R is the "business". Im onto it !:D :D

I'd have prefered the torque to the power. That was the first thing i noticed too.

Amen,when i get mine tuned,i want max torque over horspower as well,hopefully it will pull like a teenage lad!,but there may well be a method in steves madness,the fella knows his stuff by the look of things

I wonder if its possible to buy a ECU from the wreckers, fit that to mine, and post off my ECU to have flashed, say from a file he's saved from a previous tune...mmmmmm..... And is there truth to the reports that you lose the immobiliser function?

No harm in asking.... pick up the phone or send him an email very approachable from what I have herd

i dont see why not,but i wont be truly optimised i spose,but you will have to remeber that most blokes are having the timing fiddled to suit 98 octane fuel,so having it on the dyno he can listen for knock,but not so with a pre loaded tune per se,so you may have less out put than a dyno tuned vehicle simply cos of the safety factor he has to take into account for your particular vehicle,weather conditions in your area etc etc,but short of that shouldnt be a drama,and yes,you do lose the factory immobiliser unfortunately

ecu will have to match BEM, so you will need that too, so you will have to change over keys, and ignition barrel.
doors, boot, glovebox i wouldnt worry about if its just temp. just use your keyless remote and reprogram it to that BEM

So where is this re-flash wizard located? and how many pennys are we talkin?

That sounds like a good explaination to me Steevo.

Yes Shoot, like Levi said, if you're serious give S.K.R. a call.

In regard to the chat about the kws vs nm, remember going back to the previous tune or somewhere in between is just a few presses of a button away,if you know what you're doing.
I understand where you're coming from though. It's good to kick it around!
Next time I talk to Steve I'll ask.

Just a recap,you DO NOT lose the immobilser function when the ecu is cracked and re-flashed,seems to be all rumours!,i was down a SKR today to get my ROM "read" to see if he could flash it (TW VRX),and it is looking good,just have to wait till its cooler before she goes on the dyno,he also said for you interstatre members (SHOOT etc),that an ECU can be posted for him to reflash and posted back,he already has an AWD tune,now when he does my 2wd,he will have another dyno tune he can put onto yours and send back,sounds good to me

Steve

Ha ha, you'll love it!

I would pay extra and get a dyno tune. Not all cars are the same and a generic tune might work well on one car but not as well on the next.

Spot on,hence why im getting a dyno tune cos im local,but for you mexicans across the border,a generic tune that has come form multiple samples should be pretty close i would think,and hopefully tuning in this hotter weather willl allow some scope for safety for the other blokes as he cannot advance timing or lean out mixture as much,allowing more headroom for a safee generic tune

Steve

I Agree but let me tell you Steve Knight can get it very CLOSE indeed ! Remember he has done allot of R&D over the years :D :D Maybe even at Mitsubishi headquarters...... I wonder who was involved in tuning the Ralliart magna...... maybe time for a post MR SKR.

This is starting to sound worthwhile. Steevo, if you get yours tuned, I would be happy to get your ECU remap, as I run a Lukey (VRX Equiv) and the NZ intake with a K&N, same Year as well...it wont be perfect, but it will be an improvement..
As a dyno run is out of the question....

You know what the best thing is SKR is extremely well priced !! And best of all he is a great guy to boot & happy to share the knowledge as he knows what works that for sure !! :D Anyone in QLD want to ride in a SKR tuned manga PM me.

The only thing is, Steevo do you use regular unleaded, and I would need you to agree to this, i suppose, and, also have SKR save the file for me.

Agreed this is sounding interesting, just wanting to know if a TL ECU is the same as a KL or are they different in some way. Bearing in mind mine is AWD.
I would like to know because if there the same I could send down a TL ECU to get done.

No worries,i reckon mine and Zeros tune will be fairly close but he has extractors and All wheel drive,Ill ask steve if he will save the tune for you blokes,Im sure he will as he seems like a real helpful fella,**** he was there today (saturday) rooting around in the 40+ degree heat,even it if was a garret turbo on his own Lancer racecar,thats dedication for you lol,ill also get a back to back run with the NZ CAI and k & n versus the standard snorkel and paper filter as i feel a loss in bottom end torque and throttle response when compared with the standard setup,if it doesnt improve things on the dyno,ill stick with the standard setup

Oh,shoot,im tuning for 98 octane :(

steve

gee Steevo,i reckon you will have to get down to a meet and together with Al,who is always there,and we can all see a hear what the fuss is about...

So whats the KW gain +-30awkw???


Price???

And where is this bloke based??

In my case I gained 30+ kw.

Hey Chaddy, what did Steve end up wringing out of your motor? Hows the bottom end and midrange, I understand the top end is pretty solid.

Just on a side point, spoke to Steve today and when he gets back from the bathurst 12hour i will be catching up with him and we are going to test a few different air inlets to prove once and for all what works on our "street" magnas.

We'll be testing the NZ intake, the stock intake and hopefully a pod setup if someone is willing to lend us one for the test. The test car will be my car BUT before ya all say yeah but your engine is fully built etc etc, my engine wont be in my car, in its place will be a "mild" rebuilt engine that i have built for a relative of mine (im running it in in my car so that at least it has a good start in life, cos im sure it will get its ringer thrashed out of it by its proper owner lol ).

Ive got a pod box here that might have to do the caravan of courage style tour to get some testing done on it. I havent sent it yet Tim as i still dont have hold of my car its sitting in a carpark atm broken as usual.

Hi Ez Boy , 180 KWATW. Bottom end and midrange i am more than happy with and the top end is a screamer car gets really angry @ 3500 RPM and pulls all the way to 7300 RPM Very proud NA magna owner..:D Funny today damp QLD roads 100KPH on the FW in four gear back to third plant the throttle car spins wheels... that puts a smile on my dial.

Was that the one at steves today?

When i was on the phone to him he wasnt overally happy with the outcome on that car, he was thinking the NZ air inlet may have been holding it back a bit hence why were going to do some back to back test later this month.

J, Do you know what sort of Power it pulled ?

He told me on the phone what it was at after the tune but as i said before steve wasnt happy with it so was going back to trying somemore. I wont disclose the outcome on here incase the owner gets mad at me, all i will say is that he picked up just over 10kws overall which isnt oo bad for a near stock car.

Understand :)

That was mine boys on the dyno boys!,it made approx 12kw at the wheels more for a total of 131 KW,which steve wasnt that happy with,but the vrx does have a more aggressive tune than the others so may have less scope and was a bit warm at 30 degress,but im happy.seems more "lively" across the board and pulls harder IMO,im hoping fuel consumption decreases after i finish "testing" it,might take it back sometime if he comes across any other tuning advances

Funnily enough,it lost 5kw when the K&N fitted,so we retained the paper element,so to recap 131 Kw`s at the treads

Ah, good on ya mate, thats exactly what you expected!

I think that's a fantastic result... and as you have stated on the road it feels more aggressive. What other mods are you running ?
Nice one mate, yeah that the output he told me it got but i didnt wanna post it up just incase ya got mad.

hey Steevo your cars an auto isnt it? I might have to go see this fella in a couple weeks, once ive finished my zorst off. Id be happy with around a 13 killer wasp gain, 127 to 140ish would keep me happy for a bit. What mods do you have if you dont mind me asking?

No worries boys,Steve told me he had been talking to you on the blower Jason,so no dramas!,and yep Zero,wasnt to far off was i!,as for the other mods levi,cold air intake (NZ style and 98 octane fuel) and a lukey centre muffler to replace the standard one,thats it!

Flatshift,yep 5 speed tippy

Yeah thats a great result.... :D

Congrats - I think most of us would be pretty happy with 131KW from a very stock car - even a VRX.

That seems to conflict with their reputation does'nt it?

Was the K&N heavily oiled?

What did Steve think about the K&N and the possible NZ CAI restriction that Jason VRX referred to - any more info/thoughts than already posted?

Any other views from the forum?

Thats like 380 power, check out the 380 dyno sticky. Yes that K&N must have been over treated?

Yeah i was going to say the same thing about the K&N may have been over oiled.... will have to add the K&N (whats already on my car) and paper filter to the testing list for later this month along with the air intakes.

That's a good result Steeve., well done...I've always had my suspicions with the K&N filter after reading various reviews on the net, time will tell now.

Thanks,im happy with the output considering most blokes wouldnt give it a second look or thought on the street considering its a "grandpa car",so i might surprise a few hopefully.Over all experience at SKR?,Steve Knight is a genuinely good bloke with great knowledge that doesnt bull**** you around,he could have told me i got an extra 50kw at the wheel,but he was honest and calls a spade a spade,which i like

As for the K & N,hasnt done 100kms since new i reckon and is still factory oiled,i havent touched it,so no worries about over oiling etc,but i did mention to steve on the first consult that i felt a reduced bottom end and torque when fitted and he said this was odd as most respond well,but no this puppy i guess,it did the same in my V6 camry,lost torque,cannot explain it,i must have a sensitive bum dyno to feel it though

So..im thinking of this..BUT...i run on gas/tippy/k@n/full cat back redback zorst...is it going to be worth it....will the reset ecu change to way it goes on gas...being tune for 98 ron..how does this coralate with the higher octane rating of gas...will it mean there will be less of a compromise in the tuning set up because the fuel timing are now closer together...

Best bet talk to Steve

hey just wondering whats the difference between the standard intake and this NZ cai ya talking about, is our standard intake different to yours or is it an aftermarket intake from NZ?? heres a pic of mine

There are photo's of the NZ intake posted by Jason in the Street Fighter thread page 44. The NZ intake is a different design as you will see in the pictures and from the power figures provided by Mitsubishi this intake is good for a hand full of KW.

Got some photo's of one that I sold a couple of months ago.... nice bit of kit ! I decided to go the 110 MM pipe to the front bar more of a ram CAI system. This is what worked for my on the Dyno & I believe on the road also. In testing it provided 5-8 degree differences in the air intake temperature...

When Steve Knight tunes the car he can look at the temp of the air on the fly.... very handy.

Again this is what I found worked for me.

Best bet talk to Steve


Just spoke to him,as everyone says,top bloke.....yes yes and yes...he believed that doing the reflash with gas was a definate goer,as as i thought,it would bring the compromises of the gas system back closer to the petrol and with the retune ,the tuning for the closer octane ratings of the 98 and gas would bring good benifits by allowing more spark for the gas ...also metioned that getting a high flow cat would also be a good idea

now..where do i get a high flow cat...

To get maximum gains prior to the re-flash do the extractors at the same time "Pacemakers".
I cant recommend a good Exhaust shop in SA but any good exhaust shop will be able to recommend an appropriate CAT to compliment the rest of the system you already have.

Fleabay! Im just checking out universal ones, need a bit of welding but any exhaust shop should be able to handle it.

Anyone know if Steve can reflash a 380? Tune it for 98 RON maybe?

Or is the 380 ECU too different from a Magna ECU?

Yeah, I know, I could ring him, but maybe someone with a 380 has already asked.

KJ.

Mike, EXHAUST TECHNOLOGY fitted my RPW ext. and 2.5 hi-flow cat. Was gonna get a 3.5 but they talked me out of it.Obviously works ok. Do an intake like mine or Levis' for $50.

The stock cat flows fine until ya get over 150ish kws at the wheels UNLESS your stocker has started to melt/block up which may have happened with you running on gas.

Yes they can start stuffing up from the 6o;ooo ks. There'd be a few shagged ones out there.
Try an xhaust place for fresh second hand v8 or turbo cat?

went and seen steve this morning. he recommends getting a high flow cat before doing the flash as it helps alot.

after you as he mentioned someone rang about getting a tune with gas. he said when he did that steve blokes car (orange tl tw) that the cat was holding it back.

And as i said before the stock cat is fine for 150ish kws at the wheels BUT as you also said, most cars on here are getting on a bit with age/kms and what once was a good cat con will have started to crap itself by now. :) The 380 is a whole new ball game as it has 3 cats which severly limit flow (especially the 2 right up near the heads)

E.g. We have been fitting the other engine into my car today and my so called excellent "metal" cat aint looking so good now inside, hence why i will have to add a new one to my list of things to do this week before steves visit.

How many ks did ya get out of it?

How many ks did ya get out of it?

About 30000kms :rant:

****!

****!

Yeah hence why i aint happy, with my good engine in and even without a tune i could feel something holding it back especially after driving a few kms.
It was only today that i decided to pull the cat off whilst we were putting the other engine in and i saw what was part of the cause, also my flex joint is totally rooted (the internal braid has shrunk right down to about 2: in diameter) but then i already new that and have a new one to go on.

Cat flow is very important to power output it is most probably the most restrictive thing in the whole exhaust. The Ralliart Magna needed a Evo 6 cat fitted to get the max power output, the standard cat was holding the engine back. The problem is we need lean fuel mixtures to make power eg high exhaust temps, Guess what cats don't like high temps. Thats why factory fuel settings are so rich at wide open throttle. The're not fuel mapping for peak power the're mapping for a peak cat temp then trimming the spark for peak power on a rich fuel mixture, so it wil last 200.000 ks. Run leaner make more power cat life decresses real fast so thats the trade off. By the way one of the big problems with the Magnas is with standard engine pipe the divider brakes off in the y piece then sit over the cat and kills a heap of power all of a sudden. Very baffleing the first time.

The Ralliart Magna needed a Evo 6 cat fitted to get the max power output, the standard cat was holding the engine back. The problem is we need lean fuel mixtures to make power eg high exhaust temps, Guess what cats don't like high temps. Thats why factory fuel settings are so rich at wide open throttle. The're not fuel mapping for peak power the're mapping for a peak cat temp then trimming the spark for peak power on a rich fuel mixture, so it wil last 200.000 ks. Run leaner make more power cat life decresses real fast so thats the trade off. By the way one of the big problems with the Magnas is with standard engine pipe the divider brakes off in the y piece then sit over the cat and kills a heap of power all of a sudden. Very baffleing the first time.

Yep that happened to mine about 6months after i bought the car brand new. It happened on the way to port augusta and damn the car was gutless for the last part of the trip there, was a easy fix once i had a place to get to it though lol

Ok, it would be interesting to see what Steevos' car would pull with an exhaust.

Im not sure a exhaust or high flow cat would make much more difference,i already run 2.5" cat back piping,straight through lukey resonator (perforated,not louvered restrictive style!) and the Lukey LR2779 dog leg muffler,i also had the afore mentioned divider/splitter removed as it was blocking the mouth of the cat,so its pretty darn free flowing i reckon.Possibly a high flow cat may pick up 2 or 3 kw,but nothing worth writing home about,but there is only one way to find out i spose!

So,at he end of the day...was it worth it..how much difference is it on a FWD...

I think it was,people pay $1000 bucks for exhaust sytems etc that may net them 5kw,so im happy with the gain i got!,seems more eager in gears etc and im waiting for a drop in fuel use,and at least its optimised for 98 octane fuel etc that i run normally,and steve said if they work anything else out through tuning other magnas that may gain power, bring it back and he will have another go

Ha ha yes, but don't let me talk you into it!

hmmm well I have been chatting with Jason and Steve Knight as I need a new exhaust and wanted to get a tune done once its all installed.

What I have been able to glean from them so far, is that the new muffler (LR2779), hi flow cat and removal of the rear resonator is the most effective system for money.
If you're feeling rich a set of pacemaker headers, but the benefit vs money spent ($800-$950 fitted) will be minimal unless I have after market cams etc. which I don't! The Ralliart ones only net about 1kw so the stock ones aren't really limiting anything if the motor is reasonably stock.

So once I get it all installed I will let you know how it all goes! My car in dead stock form running on Premium got 115fwkw at the AMC dyno day a while back so I will get a after exhaust/before tune dyno and after exhust+tune dyno to see the individual step benefits.

what car do you have? 155fwkw? isnt that what the stock engine is rated at?

Didnt Ih8HSV's vrx only get 129fwkw?

oooppppss!!! Typo! Sorry, was 115fwkw! :bowrofl: I wish it was 155! Fixed :D
I have a manual TH Sports.

Hey man that dyno day your were at in 2006 (i think) i also had my TH sports on the dyno that day. Now at that stage my car had a bog stock engine in it except for my pacemakers, hi flow cat and a magnaflow rear muffler, it also had the "98octane" tune in it that steve will use as a base for your car.

It pulled 137Kws@wheels, so i reckon that will a give you a rough guide on what you may achieve when ya get yours done by steve. :)

So, How is your fuel consumption after the tune to 98 octanes? Have you achieved a stable enough day to day driving average fuel consumption figures?

Would this be better than using a haltech platinum tuned to 98RON? Can he reflash and tune the factory ECU if i get the haltech in and tuned? It is a piggyback after all.

12.2 litres per 100kms around town only,driving briskly!

why would you bother?,you are changing the same thing with both,mixtures and timing,i would prefer Steve to tune mine as he did,rather than a random bloke tuning the piggyback,he knows these engines inside out

Oh,you couldnt have both at once,only one would work!

Well if i need to i could just pull out a plug and let him try a tune and keep the better one.
