Update:
For you guys that are really interested in doing something like this yourself. Please click on the link below and read the whole page. Also there is a great forum available as well which I just joined. I should have the virgin ECM back this week from Beckman and have the the Star Diagnostic Compact 3 system here within a week. The T-30 laptop required to run Star DAS, arrived a couple of days ago and I am writing this message on it, so I guess I can give the seller positive feedback. I had a mechanic that I was going to pay to help with the electronics, but after months of studying I decided I wanted to do it myself. I also found out that the mechanic had no experience with developer mode which I believe will be needed to make the car operate normally. Most mechanics have little or no knowledge of developer mode. I am studying every chance I get now as October 16th will be here soon and my uncle is itching to rip that V6 out. He is coming here from Redlands CA where I grew up.
