No, however the data for the long term fuel trims will be erased, but that is no big deal as they’ll b re-learned. This happens regardless if the PCM is stock or aftermarket.
I have got a 2003 VY commodore V6 S Pack auto, if for some reason I take my battery terminals off which resets my PCM, will the tune files from Mace be wiped from it ?
