I have to make a decision on which ECU to use... what is your preference.. and why?

Thanks!

It still depends on the rest of the vehicle, but I would go with the E38 since it had an available OS with the 4L80-E. Is going to a 24x crank reluctor out of the question?

BTW running a 4L80E can be done with a 4L60E TCM OS or PCM OS, Id worry more about what ECM OS you want to run then pair an appropriate TCM OS to it. I believe you need to switch around 2 or 3 pins to make a 60E cal run a 80E.

Thanks Chris, I think I saw a how-to on this... let me "search"... :)
