Does anyone have a tune for a 93 lt1 with cam and headers that I can load. $da3 or $da2. I'm new to tuning and would like to compare the bin with what I have. ecm had g1 adapter and chip in it when i bought it and i would like to try and figure out what they did. I am putting the engine in a 1972 chevy c-10.

Wouldn't you want to compare it against a stock bin to see what was changed? Do you know if its a vett or f-body tune?

Not really interested in the stock tune. the motor has had a cam and headers installed so the stock tune wont really do me any good. I'm trying to find out what other people are doing compared to what is done to it now. It came from a 1993 f body car that was totalled in the rear end.

All im going to do that wasnt done to it already is delete the egr and vats.

All I was saying is to take the stock tune and compare it to your custom tune. That way you can find out what parameters they changed from stock.

Your custom tune might be a good starting point if the person who tuned it knew what they were doing... the only difference from stock that the "custom" tune that came with my LT1 had was to turn VATS off.

Personally I would start with the stock tune and see if it will run. Datalog and make your changes from there.

I compared them already. The only thing that was removed is the vats. I also changed thee coil and opti and the icm. now i have spark at the coil but nothing at the plugs and no injector pulse. This thing is kicking my butt!
