There may be some hidden instructions in the 88 that I can't see. I asked my son to give the black 88 from Dave a try. It has a freshly programmed Prom and is bone stock as far as I know. I tried my car on the move today as I was leaving my cottage. We just had over an inch of rain in a couple hours so I was just idling out. Start up coolant temp. was 21*C, backed out of the shed, hit the door close button and idled away. Maybe got to 15mph but no more. It is about .2 miles to get to my property line and just as I did so, coolant reached 40*C, loop light came on and O2 started blinking. No apparent difference between moving and static.😎
