LT1 intake

i Just pickd up an LT1 intake but i currently have an LO3. Can i use my ECM to convert to multi point fuel injection if i get my prom burned? or will i have to buy a new ECM and harness all together? i know that edelbrock has an entire kit that converts TBI to MPFI and just modifies the harness and adds a new chip to make it all work. WIll this work or should i just get all different ECM and Harness and stuff?

You need a new ECM (7730). I picked mine up on ebay for 30 bucks. There is a thread here on TGO; search for "repinning harness" and you should find it.

It tells you how to repin your TBI harness to adapt to the TPI computer. Repin it and modify a couple of wires and your set.

Then your probably gonna want to do some research at the PROM board and get into tuning because that LT1 intake is gonna want some tuning work done I'm sure.
