GMT800 Fuel Gauge Signal Hello again,
Ever since I started messing around with tuning my truck I've noticed that my fuel gauge reads backwards, not even incorrectly, just perfectly backwards. I was going through my laptop today and realized I had a different XDF for my PCM that had showed an option for enabling PWM fuel gauge signal. In the XDF I have primarily tuned with this option did not exist. I have tried flipping the fuel gauge calibration and that kept the fuel gauge from working at all after it's sweep. Unfortunately, I don't have an XDF for my original OS so I can't check what was set up by default, but does anyone have any ideas on whether or not the GMT800 family used an analog, PWM, or if the BCM controls the fuel gauge? If needed its an 03 truck.
