Ok the fuel gauge moves but it is reporting about 20-25% higher then what it should be in efilive. The volts at full is 2.7 volts is there a conversion from volts to pwm so I can set this this gauge better?
Need to mod fuel gauge calibration

Hello Cool28,
What type of fuel sender (or vehicle) are you working with, and what PCM and calibration are you using ?
I believe GM has used at least 3 general types of fuel sending units over the years:
- 0 to 30 Ohms (empty - full)
- 0 to 90 Ohms (empty - full)
- 240 to 33 Ohms (empty - full)
The above values may not be exact, but represent the general range.
Regards,
Taz

This is a 98 transam with a 02 PCM. I been uploading numbers and it looks like 116 for 100% full on gauge is close to efi 100% but after that it doesn't add up. I had 4 gallons left in the tank and it showed half full yet lol

Hmm well I don't know it must creep up when running cause the cal numbers are right just checked it. Maybe my sender is going

I'm not that familiar with 1998 LS1-A systems ... I recall a thread somewhere that discussed using an 2002 Express (I think) Fuel System segment when upgrading to a 2002 OS ... may have been a Corvette thread ... not sure if it is applicable to your Camaro.
