L92/LS3, e38, 4l80e…
I also run a 4l80e.
I have the E38 ECU from the ‘09 caddy in was pulled from.
Can/should I use the E38 with a T42 TCM? I’m not married to the E38 if there is a better OEM option for my combo.
I’ll be using HPT to tune, I have some reading to do on the HPT forum but I believe that I can use any T42 with an E38 and reflash the TCM to the calibration?
