Does anyone know how to disable DTCs in the A40 TCM? I have two TCMs, one that's tuned and one that is stock. When I plug the stock one in I get P0827 from the TCM. When I swap to the tuned TCM I don't see that code. Looking in EFILive there doesn't seem to be a way to disable DTCs. Is this something my tuner would have done with a cax file? I've asked, they won't say. This is in a swap so there isn't a column shifter to fix a broken wire on.
