fuel gauge ohms

[Taz]

Hello John,

You will need to measure the exact ohm output of your tank / sender combination - at empty, 1/4, 1/2, 3/4, and full. Then adjust F0507 - such that the PCM will accurately calculate the fuel gauge output sent via Serial Data to the IPC.

F0507 settings may take some trial and error - A/D values appear to be the inverse of the sender ohm output - not sure. Your tank and sender combination are non-OEM, so you will probably have to develop a custom calibration.


Regards,
Taz

I tried adjusting the values slightly, than I went extreme to try to get a reaction and nothing I do to that table will affect the needle function. By putting the values to max or min I was expecting to bury the needle in either direction but it doesn't change and it still works the same as it always did.
