Re: propane butane ratio

You can buy straight propane from Supagas, usually cheaper than the servos too.

IIRC LPG is a 80/20 mixture here.

Nemesis - i ran into similar issues with my supercharged v6 commodore a couple of years back. My problem ended up being a combination of poor tuning and injectors that couldn't flow enough gas. Basically once the engines rpms hit ~4000rpm the injection times went thru the roof and the gas injectors ...

Icom have a Liquid Injection system out. Theres a bloody 3-4 month backlog here in oz for it as every man and his dog with a V8 wants it! (literally).

IIRC one of the test cars with a 4.0Ltr Turbo V6 made 21kw more than petrol with the Liquid Injection without a retune.

"The fuel usage using JTG is within 5% of petrol unlike vapour injection which is only within 20%" I am a little sceptical about this claim. The main reason, as I understand it, that LPG does less MPG than petrol is that it has 15% less energy than petrol, not due to the LPG vapour system being les...

Here in oz all vehicles running LPG are required to have a little diamond badge/sticker on the number plate saying LPG. Is this not a requirement over there?

Question - Is the "injection time for running on petrol" in reference to when the system will switch back to petrol when the gas injection times hit that?

A VY Commodore is a Holden, basically a monaro with 4 doors. He SHOULD be getting roughly 400-500kms from a tank city driving and 700+ on the highway.

If the sensor is faulty, pouring water on it seems to allow the car to start normally, at least this is the case in oz for cars with hard starting issues.

Even better would be to take the car in and get the diagnostic codes pulled from the ecu.

Knowing what sort of car would be a great help.

Is the starting issue only when the engine is warm? If so try pouring some water over the CAS (crank angle sensor), when they play up, the car wont start/ have difficulty starting.
