Hi there I'm new to this forum and are looking for some advice, I own a supercharged 3.7ltr
I5 in a 2007 H3 Hummer. The kit I am using is designed for a 2008 model and fits the 2007 no problem until it is time for tuning, the 2007 has a PCM for both engine and transmission, the 2008 has an ECU for the engine only and a PCM for the trans etc. My tuner has started from scratch with the stock PCM and has done a great job except for a few niggling little problems that he believes is from the limited adjustable perameters using EFI Live.
Has any one on this forum piggy backed a Motec or similar to there I5 for tuning a forced induction engine ? and if so what did you use and was there any problems with the trans function after fitting. Here in Australia there seems to be no one who has fitted an aftermarket ECU to an I5.
I have attached some photos of my set up.
