I appreciate the input and understand I can lock the TCC from the ALDL but I want to do sort of the opposite. I want to unlock, or block, the lockup under conditions of boost at low throttle openings. I know this is sort of a Rube Goldberg, but since I am belatedly aware of how little throttle is required to have above atmospheric conditions in the intake, under some conditions, that it seems most expedient. Hopefully it is more temporary than permanent. Eventually maybe the chip can be programmed more appropriately to address high load and relatively low rpm. At this point probably easiest just to cut the wire near the ECM since it is laying on the floor anyway. Maybe a three position switch for the TCC, off, normal and automatic? Now I just need to scare up the ambition?
