had the gas tuned on the ute a few months back, that runs fime all the time. nice and smooth etc

but when i drive on petrol it seems to idle rougher, even change gears rougher. when it gets up to runnin temp it smooth out a bit but is still noticably rough at times when sittin on a consistent speed.

not sure if theres different tune settings for lpg or petrol or what the go is. seems to run really rich with the petrol.

i have no idea wether gas tuning is directly related to petrol tuning aswell, if you catch my drift. through the efi

any advice would be appreciated, so just thought id put it out there

If you are asking if the guy who tuned it could stuffed up your petrol tune, the answer is no.

he may have adjusted the ignition timing, which will effect the petrol side as well, but you would be complaining about a detonation problem.

right. well it wasnt great before then, just wondering if petrol tune has any relevance to gas tune?

i didnt think theyd have anythin to do with each other. like my old carby ute is just a screw valve on a hose off the mixer

but i have no idea what the deal with EFI is

is the majority of ya cars runnin on gas ? has it been tuned fa gas?


me wagooon runs betterer on gas than petrol
