6L80E in a 4th gen with an LQ9?
#2
It's behind LS7 so I'm using PCM for it.
Looks like using LQ9 PCM will be a problem. I believe the LQ9 has a 24 reluctor ring. If it has 58 reluctor ring it'll work.
You may want to check out Mast MotorSports. They have a PCM that will communicate with 6L80 and 24 reluctor ring LS engine.
