Hi,

I am not very happy about the consumption I am getting from my ED following LPG conversion. Currently I am getting between 20-22L/100km and I have been driving conservatively. It runs like s**t on petrol but I am informed that because it's tuned for gas. The fitter is not exactly answering all of my questions either.

System includes: OMVL-r90 convertor, Sprintgas venturi and Gastec FP32 processor. I replaced leads, plugs and 02 sensor. I am planning on retuning the LPG system using the sticky on here and also the tuning instructions supplied with the processor.

I have noticed something else too - my transmission shifts have changed. I can't tell you exactly how, other than to say i think it's short shifting. Having read a fair bit on here I think I will also reset the ECU and perform the learn throttle procedure beforehand.

Is it foreseeable that this will affect my gas 'tune' adversely, and that I am stupid, or will it likely all be good?

id go find another tuner dude

the car will be tuned for gas to an extent, it should not affect teh fuel eccon as much as u have said
and should run on petrol with no worries at all

i would say the fitter has no idea on what he has done or is doing
have u also checked the dizzy cap and rotor?

A lot of car owners are starting to switch to Hydrogen (on demand) boosters, I have been running one for awhile with petrol and it seems to cut my fuel usage back and the car runs a lot smoother. My brother (who has been running 1 for years with gas) swears by it, he had his dyno tested and with the booster running has was getting a 35% power boost and a cut in gas usage.

just check out "youtube" on hydrogen booster's and make up your own mind about it, I know it works for me :lol: :lol: :lol: (all the way to the bank)

cheers AL

It was just a suggestion mate, I know that when you go to gas after petrol it will feel like you have lost power, so most compensate by giving the thing more loud pedal therefore using a lot more gas than they intended too.

With the car hydrogen boosted it will (most times) increase the power a bit which may inturn keep the foot off the loud pedal a bit more and save on gas... But yeah I understand if he is having tuning problems - then try someone else to tune it.

cheers AL

yep tested on a dyno and all - I didnt believe it either untill I saw the paperwork. I should have said 35% performance boost with it running

sorry my bad :roll:

are you here to sell something???

start a new thread if u want to talk about other stuff...

the only thing the tuner could have dont to your car to make it run better on lpg is to adjust the timing...u should check that..

Well I did my own tune and got the following results;

1) Better starting

2) Smooth idle

3) Lambda point at both idle and 3K rpm (as per manual) unlike previous "professional" tune

4) No apparent power loss compared to previous tune

I will have to keep an eye on consumption but at this stage I am happy.

Kudos to the guys here who put together the tuning sticky and updates!

I haven't checked the timing but did tell the tuner that I wanted the timing advanced to optimise for LPG (95% usage). I will presume that the s**t petrol performance has something to do with that.

I don't have the means to check it myself, at least not yet.

I just had my AU converted to gas & I dont think the installer did the best tuning job.

Is it possible to get that "Gastec FP32 processor tuning instructions"? I think my installer dosn't want to miss out on potential future business. I'm pretty new to this sit, so could you give me a link to the "tuning sticky" that you mentioned?

It sounds like I have the same set up as you, any hints you can give me?

Thanks mate!
