I recently swapped to a 0411 PCM in my 1999 Suburban K2500 (7.4L). Since the swap, my fuel gauge isn't reading correctly. I've tried adjusting the settings multiple times, but the gauge either stays on empty or reads way over full. After copying a tune I found on the forum, the gauge now stays stuck around 70% all the time.
Does anyone have any advice or know the correct settings for the fuel gauge calibration after the 0411 swap?
