My alternator isnt charging very well. battery and alternator are new, im only getting about 2 volt signal from the PCM to the two pin connector (on both the grey and brown wires) I cant find any settings in HP tuners for this...do they exist?
Im running an LQ4 engine in my truck (used to be a 4.8), running the LQ4 pcm, and the original harness from the 4.8. Now the original 6L harness used a 4 pin connector and the truck is running the 2 pin style from the 4.8. Almost thinking I need to go back to the 4.8 pcm, load the 6L swap and segment swap for the 4l80e
Thanks for the help
