As some of you may know we had the car converted to LPG about a week ago. Today I drove to London on LPG and I noticed that the petrol gauge started to go down very slowly (about 5 litres per 90 miles). I thought there is no way it can be using petrol so I phoned the conversion people and they said the car computer was altering the fuel gauge level because it detected that the car was travelling (the LPG tank gauge is seperate and they are not connected)
Anyway they said it would probably reset after I switched the engine off. So after I stopped the car for a few minutes and then switched it back on the fuel gauge goes back up to the level I expected (increased by about 25 litres).
Why does the computer do this rather than just measure the fuel in the tank. Is it for some sort of auto calibration. The conversion people can install a reset module to stop this.
