Did the swap and everything is good and works as it should except fuel gauge. i know 98+ goes through pcm and i have that wired properly. my problem is in the tune and from what ive gathered is black box was output duty cycle and the 2001 pcm is pwm. ive tried different tunes for segment swaps nothings compatible and messing with fuel sys tab in hptuners ive got the needle to move buts its mostly empty, almost on fuel, or gauge be stuck in the 3 oclock position.
