Default HP Tuners "Write Entire" to wrong ECM, now can't write anything to it.
OK HPT experts, got a dilemma.

I have 2 different E67 ECMs, one is GMPP & the other is 09 CTSV, I can/could write to both of them without issue. But I mistakenly did a "Write Entire" of the GMPP tune to the CTSV ECM (which worked), but now I cannot write anything to the CTSV ECM, says vehicle not recognized, or registered, or something like that.

Am I hosed now & have to use more credits to enable that ECM again? Or is there a way around it?

Thanks
