Have been able to get some good communication happening with the MMA regarding LPG conversions to post 2002 magna/verarda range of cars and am wondering if others have got some information to share on this fuel that works very well in a whole range of Magna/Verarda cars. At this stage we are able to identify which cars are really LPG compatiable and which are not and more importantly why not. For those at the nationals I was the bloke with the AWD verarda on LPG. My car is backed by a full MMA warrantee dispite a memo put out by MMA that Verardas should not be converted to LPG.

The reason given is that any Magna/Verarda with traction control is not a suitable candidate for LPG conversion as MMA testing has found cases of engine backfire under traction control conditions which could lead to premature engine failure, as the AWD doesn't have traction control LPG is not a problem. MMA advise that people who have LPG fitted to a car with traction control turn the traction control OFF while running on LPG however it still can not endorse the use of LPG on these cars.

Other stuff I'm looking into is a interface module to adapt the cars information computer to work when switched to LPG, there is a factory module that works with the factory kit but it doesn't at this stage work with the superior Parnell LPG system.

In the meanwhile I'll keep cooking on Gas, by the way with my Coles docket I'm buying LPG at 34 cents per litre in Melb.

I have a '99 TH Advance on factory LPG. The heads themselves have LPG stamped on them. So i guess mitsi did some head work to allow the use of LPG without the need for a valve save bottle. The factory kit is an Impco system. I thought that was the bees knees of gas systems. Never heard of Parnell.

There's lots of info on gas systems at the ALPGA site (www.alpga.asn.au i think)

Some really good stuff happening with Autogas, even direct LPG injection! (mmm at that octane the power has to be schweeet!)

I know this as I edit the motoring section of the newspaper I work at... lotsa press releases from them lately...

LOCALLY DEVELOPED AUTOGAS INJECTION SYSTEM DELIVERS
ENVIRONMENT BOOST
An innovative Australian-developed autogas vapour injection system gives
motorists the chance to “have their cake and eat it”, delivering strong
performance without the fuel cost and environmental penalties.
The Gas Injection Technologies “Stealth” injection system has been used and
tested extensively on a 4.0-litre BA Ford Falcon.
It offers comparable and in some cases increased power compared with
performance on premium unleaded fuel - while reducing emissions.
The Gas Injection Technologies “Stealth” injection system is designed to
replace a car’s existing petrol injection fuel rail and injectors.
The Stealth system fitted to a BA Falcon reduced combined gross pollutant
emissions to less than one tenth of the level achieved on petrol.
Managing director and Stealth system designer Bill Campbell said the system
is more sophisticated than the latest generation of imported autogas injection
systems.
“It uses the car’s existing engine management computer to minimise
complexity and the injector units are designed to suit large-capacity engines,”
he said.
“On the BA Falcon, it reduced carbon monoxide (CO) emissions by 94.1 per
cent compared with petrol, and cut combined hydrocarbon and oxides of
nitrogen (HC and NOx) emissions by 60 per cent.”
Mr Campbell said the European autogas systems are designed for engines up
to 2.7 litres, with a second computer added to the engine management
system.
“The GTi Stealth system is so named because it is virtually undetectable
under the bonnet and operationally drives as well as or better than the
vehicle’s original petrol engine configuration.
This system seamlessly integrates with the original vehicle computer.
“It makes maximum use of existing components, such as the engine
computer, to minimise complexity and maximise engine efficiency,” Mr
Campbell said.
“The more you integrate into the vehicle’s existing emission control system,
the better.
“On the BA Falcon installation, we use the original fuel rail.
“The difference is that when you inject autogas, the injectors have to flow 300
times the volume of fuel in the same injection period - because they’re
injecting a gas in place of a liquid.”
Successful tests with the GTi Stealth injection system confirm the
performance potential of autogas as a fuel and the new generation autogas
injection systems, which inject fuel directly into the inlet ports.
Cars fitted with modern autogas fuel systems produce lower exhaust
emissions than either petrol or diesel-powered vehicles.
Autogas offers a performance increase based on its higher octane rating.
Autogas is locally produced, lead free, clean burning and an important
contributor to reducing greenhouse gas emissions.
(Autogas is the generic name for LPG used in vehicles and is promoted by the
Australian Liquefied Petroleum Gas Association.)

AUTOGAS PIONEER GIVES NEW TECHNOLOGY THUMBS UP
One of the first private motorists to experience the new generation of Liquid
Petroleum Gas (LPG) fuel injection systems has given the new technology the
thumbs up.
Sydney motorist Ian Mercer says the dual-fuel system fitted to his recently
purchased Mitsubishi Challenger four-wheel drive gives the vehicle
performance on autogas every bit as good as its performance on petrol.
“I have a very steep driveway to my house and on autogas the Challenger
pulls just as strongly as when I switch over to petrol,” said Mr Mercer.
Mr Mercer’s Challenger was the first vehicle of its kind in Australia fitted with
the new BRC Sequent system from Impco Technologies.
The system was developed for use on the 3.0 litre V6 engine in the
Challenger and Triton models with the co-operation of Mitsubishi Motors
Australia.“Impco asked whether I would like to be a “guinea pig” and field trial the new
technology in my car and I’m very happy with the results,” said Mr Mercer.
The Challenger’s fuel economy on autogas has also been impressive,
returning consumption figures just 1.5 litres per 100 kilometres higher than on
petrol.
“With autogas selling for less than half the price of petrol, I’ve calculated I’ll
save between $8,000 and $10,000 over 100,000 kilometres,” said Mr Mercer.
The Impco BRC Sequent system has been approved by Mitsubishi Motors
Australia and can be fitted without voiding the factory warranty.
“All our engineering work on these models has been inspected and satisfies
Mitsubishi Motors Australia’s engineering targets,” said Impco Technologies’
business manager, Rob Mercer (no relation).
The system can be ordered through Mitsubishi dealers for fitment on five
models – Challenger, Pajero, Triton ute, Express van and Magna – from
January.
The Impco-BRC Sequent system uses state-of-the-art “common rail” injection
technology to improve performance and fuel economy and lower the
emissions of autogas-powered vehicles.
“Third generation LPG engine technology such as the Impco BRC Sequent
system overcomes the traditional limitations of running a car on autogas,” said
Mitsubishi Motors engineer Rob Chadwick.
“The performance and fuel economy gains we’ve seen on our cars fitted with
the system make a compelling case for LPG,” he said.

Ford had the same problem with LPG vehicles, it wasnt a problem of engine wear though (dont forget they have factory built, factory warranty LPG vehicles), they found that it was possible to damage (in some cases possible it could set fire to?) the air box as the pressure wave raced back up the intake. They fixed the problem by replacing the air box with a new design which had springs located on it instead of clips, now if it happens the lid can raise and let the pressure drop without damaging anything. It has happened once or twice in the magna before (run an impco system too) and it hasnt done any damage, im wondering just what they think will suffer due to it? a rod or something similar?

I dunno. I'm mostly interested in what a gas-injection system would do with either a smaller twin-turbo setup or a larger single turbo.......

I think in 10 years time, most of us will be on gas, and transitioning to Hydrogen (either as a fuel cell or as a replacement internal combustion fuel). I am most interested in the fuels that we are all going to use in the future. There's some really interesting stuff out there.

Mazda is currently trialling a Hydrogen powered RX-8 with rotary engine..... Massive reductions in Nitirc Oxides and particulates. I did a story on it in my newspaper ages ago, will try and find a PDF if anyone is interested.

does anyone know of any magnas running on LPG? Please tell of experience.

I have a KE Verada 3.5 on LPG. just done 109,000km.

The gas fitter was a Dodgy Brother from Marrickville (The only gas fitter in that suburb - don't go to him!!!) who installed this reverse conical mixer that looked like it was sand cast in his backyard using empty KB cans!!

Larry Mulder from Wollongong put a real mixer in and the car runs well now. Only problem is an intermittent stalling whilst braking with the engine idling in gear (if you know what i mean :confused: ). The system has never beeen exhaust gas analysed so I suspect that if I got it tuned correctly, then this would disappear.

I got 540km from my tank whilst driving over the Alpine Way from Canberra to Albury, then a bit down the Hume. Very happy! No discernable loss of power either, but I'm no leadfoot either.

No discernable loss of power either, but I'm no leadfoot either.That's excellent range. did they fit the tank in the boot and how big is the assembly in there? how much was it? would one lose warranty with mitsubishi if its still a new car?

Hi, below is a problem that i have is this what you are investigating with your interface module? as the service book tells me that the trip computer will work on both fuels.
I converted my TJ over to dual fuel last week and ever since then i have been getting incorrect readings on the trip computer. For example i have a full tank of petrol and very little gas yet the trip computer indicates while i am driving on petrol that i only have 150km's left in the petrol tank which would be correct if i was driving on gas but i am on petrol. The other anomaly is that if you are driving on gas or petrol the average fuel consumption being shown is in the mid 40 litres per 100kms. Has anybody experienced this or know of the problem as the installer does not know what the problem is. The fuel gauge is used for both petrol and gas.
Thanks in anticipation!

My LPG system only uses the fuel guage but not the trip computer for some reason, for example, I drive 300km in one trip on gas & the 'puter tells me I have used no fuel at all!! It was only installed 3 months ago, & dealer says it won't work with the 'puter. Am interested if anyone knows of a fix for this.

i would love a wiring diagram for the monogas magnas might be able to work out why....

Hi I just convereted a 3.0 ltr TF, the guy that did the conversion said it was all tuned fine.
It gets about 16.5 litres per 100 is this normal????????????????????????????????:doubt:

Let it settle for 1500kms or so. This should be enough for the system to settle then take it in for a tweak / adjustment. If its a mixer system probably is close to what he says but should be a little better.
Not this is a very old thread see the first post...

Also to the OP, who is probably long gone and driving a Falcon now, its VERADA not veraRda, tard.
