What is the exact process for using hpt to make an auto pcm run manual values and eliminate the dtcs you get with that as well? Reason being is I am using an 03 cavy pcm that was auto. I need to get the pcm to follow my 02 sunfire's manual values. or just simply using the vin switching option would take care of that?
you mean burn my tune from my sunfire to it? but because they are different vins will it mess anything up?
