Checking in on this. Got my IC7 fully replacing my stock dash. Emailed Haltech but they arnt getting me an answer I need. 93 R32 GTR Green/Blue wire in AVI 18. Red/Black grounded into 30 on the IC7 also spliced with ground from body so it's not so erratic for signal. 2 issues. 1st is when the cars not started the Voltage reads about 0.01 full and 0.29 empty. When car is on its changes to 0.19 full and 0.54 empty? Also any time I go over 3000 rpms ( doesn't matter which gear or speed ) voltages jumps .20 so gauge then drops to empty??
