Well I ment flash the V8 tune in before I tried to run it. I gues what I ment was Is the hardware the same as long as it has the same OS?

This is a brandnew GM ECM. It has no tune yet

It says it during test

I am using V2 . service # is 12597121. Gen-IV V8

It is telling me that it is a loss of comunication with the ECM.

The car was wrecked and was bought from copart. Do I flash it and then do a vin change and then a vats relearn?
This is a ZO6

Can a person flash a new ECM with a toon file with the same OS?
The ECM was stolen and I had to buy a new one.

I Had a v6 in a toyota Painless wiring harness and some of the wires for the injectors were in the wrong place

If it has been sitting along time I would replace It but if it hasn't then I would try it.

Can and how can I put one tune with a vin to another vehicle with the same os? Do I just change the vin?
Use one tune for more than one vehicle.

Will tech II reset lock so efi can unlock it?

Does GM have a lock on any ECM's from the factory? I have one showing locked.
