I'm wondering if there are any internal differences (injector drivers for example) V6 vs. V8 within the '0411 PCM? Usually I get V8 '0411 PCM's, but this time when I read the calibration, it was flashed as a V6.

It does not make sense to me that GM would build a PCM, knowing there could be many different engine applications the PCM would be used for. It would seem to me that GM would build the PCM to fit as many engine applications as possible. Maybe the volume of production would allow for a V6 '0411 and a V8 '0411? The cost savings of parts for 10's of thousands of PCM could provide a substantial production cost savings?

Maybe there is a way to look at the circuit board inside the '0411 to know V6 vs. V8?
