Hmm, I have two LS setups..

First is up and running/driving well, Thats a 1971 Jimmy, I have an Gen III LQ4 and 4L65e, both are run from the single ECU, a '0411' Red/Blue ECU.

The second is a stroked LS2 Gen IV motor, from a trailblazer SS. This is going into my 67 Plymouth Valiant.. probably with a 4L880e. That one I have a stock E67 ECU, that controls the transmission also (can do 4L60s, 80s, and 6L80s with it). So it's possible.
