I about have my new LT1 finished and I am looking at options for the PCM. I have used a Do It Yourself fuel injection system called Megasquirt (http://www.megasquirt.info) on a few other motors i have, and considered doint it for the lt1, but I have the 95 ecm and complete harness.

does anyone have some screen shots from LT1 Edit of the fuel tables and the spark tables? can you tune it in speed density using VE tables?

What will i need to do to the ECM to get it fired on the 95 GM ECM

here's what I got
1995 LT1 engine, stock heads w 2.00 1.56 valves, some porting, GM LT4 hot cam, 1.6 rockers, eagle 3.75 stroke crank, eagle 6" rods, srp -16cc dish pistons. .020 overbore = 381 cubic inches.

i've been told that the LT4 cam will run fine on a stock computer, that the MAF will correct for the cam. now i have more cubes, and dont know for sure.

anyone running a N/A 383 with a lt4 cam? anyone have a LT1 edit file of their tune i could look at?

Thanks!!!
