Jackeroo converting to gas.

I have been told that there are problems - how many ks have you done since conversion - are you in Melbourne.D

Just covered over 20,000km with the conversion.
Apart from a wire dropping off a solenoid (which had me thinking I was loosing petrol) actually I was running on petrol even though the gas controller was telling me I was on gas the only other issues I've had are purely tuning related (ie. wont' start on gas when cold, flat spots, power dropping off at high revs).
I finally found a good gas mechanic and when it's tuned right it goes great. There's barely any difference when on gas or petrol.

In 1988 Sweden unleaded was $3.50 Aus per litre. I would not like to run a car up there in 2005.

I requested the flash-lube system be installed when I got the conversion done but several mechanics have since told me that it's not effective. flash lube is currently disconnected.

The place that did my conversion had already done 12 jacks in the past 2 years which is the reason I went with that particular place.

I remeber seeing this type of system as a prototype on an EA or EB falcon in a documentary in the early 90's . It's taken a long time for it to get on the market!

I was wrong about it being a "Parnell LPG kit" it's actually an Impco gas vapour injection kit built for Holden and supplied by Victorian Autogas here in Melb. The guys next door use Vic Autogas as a supplier and fit this sytem to new Holden Rodeo's prior to the customer picking the car up from the dealer.
Apparently components are available to retro fit to a number of fuel injected vehicles and are then progammed with the laptop. (the rodeo's are pre-programmed) It costs about an extra $1000-$1200 to buy this kit versus a standard Impco system.
They must be doing a few systems for these now as the new Toyota Hiace (the one that looks like a block of flats) from Vic Autogas had a sign on the side "I'm laughing, I'm on sequential injection LPG"
I've been told there doing a kit for the Gen 3 V8's as well, now that would make a nice conversion.

Andrew, does this system still use a standard style convertor ? or is it fed as a liquid to the injectors?

And do you know if they suffer the odd afm destroying backfire like earlier gas systems ? I assume being ecu controlled they wouldn't.

Thanks champ,

Brad, from what I saw it is a completely different style of convertor but it still converts from liquid to gas hence "gas vapour injection" The one on the Rodeo has the gas line run through a pair of filters after the convertor so any "junk" which can occur at times is filtered and it can't block the injectors. A very useful addition in my opinion as I have been the victim of a bad batch of gas residue fouling the mixer in the past. There is no mixer in the inlet tract so air flow isn't compromised as it is with normal LPG conversions. Serious backfires are usually caused by the fact the whole inlet tract is filled with LPG/air, but this new system only has gas in each inlet port injected when it's needed on the induction stroke so backfires should be a thing of the past. The one thing I didn't like on the Rodeo install was the fact the gas computer was located in the engine bay up near the front of the car and in a 4x4 situation could possibly be a problem with water crossings, but these Rodeo's I saw were 4x2's anyway so it's not a problem for them.
Regards Andrew.

Thanks Andrew, geez i like the idea of a new style convertor with filters, that will solve a huge amount of dramas right there. I'm with you, never liked the idea of ecu's in the engine bay, let alone on top of the manifold like the v6 rodeos. Might have to look at it as an option on the jack, but i think i will be strugling to put that much cash up front.

cheers mate, brad

I don't necessarily agree. A mate who is a motor mech had a mid 90's Rodeo on gas and the thing kept flogging out valve guides. All he could put it down to was running on gas was too hot for the combustion chambers and the lube for the guides got vapourise for want of a better description so they were running 'dry'.
