How to go back to Injection? - Third Generation F-Body Message Boards

Hey fella's, about 3 years ago, I went from TPI to carb and now am wanting something a little more street friendly. I was wondering if I could use any TPI ECM as long as I get a custom chip? Also, I am going to use a painless wiring harness to take some of the headache out of it. The car has TFS heads with 10.5:1 compression, it will have a larger hyd roller cam 234/244 @ .50 on a 112 lsa and I will be using a Stealth Ram setup. I would like your inputs on which ECM would be the best, MAF or SD (730 or 727 etc)? I may go with a slightly smaller cam but am unsure right now. My car is an 89 originally a 5.7 A4 car, now it has a 5spd though. Any help would be great.
Thanks,
Brit

SD,
and you might as well resolve yourself into getting into doing your own chips. Each engine is just enough diffferent your not going to find any one size fits all generic chip to work correctly.

That is my next question, is there a write up somewhere that can teach me how to get started? Will SD handle that much cam?

Thanks,

Go over to the DIY-Prom board and see the stickies. After that look and search around some. Jsut about everything imaginable has been gone over.
