ecm no. 16159278
it is not a flash. i have to burn the chip with a burn 2 and install with an adapter into the ecm.

I have the chiltons and haynes mauals. I just can't figure out why im only getting .5 volts instead os 5 at the refernce points aand i have good voltage everywhere else.

i have spark at the coil but not the opti. and i also have no injector pulse. the puzzling part is before i changed the coil i had barely any spark there. thats why i changed it out. then i had no start so i changed out the opti. im starting to think the ecm may be bad.

Disconnected the battery fro 2 days, I also have a noid light plugged in and do not get anything from any of the injectors ( tried them all). I have the 12 volts at the pink wires on all injectors and also have good fuel psi. for the life of me I can't figure out what is going on.

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!

not that i can tell. i have spark but no fuel. the injectors are not firing. i put the motor in a 1972 c10.

unchecked the set box on all vats boxes. it is turning over but will not crank. i cranked it with starter fluid but it dies quickly. everything else is working but it will not start.

how do i turn off vats? thought i had it but it didnt work?

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

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.

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 ch...
