Re: where is it? (LayZ)
The only BowTies I'll be wearing are on my front emblems! :chevy
Getting a PROM or a MemCal?
MemCal: plug it into ECM n go.
PROM: unsolder old, resolder socket, plug it into MemCal, plug it into ECM n go.
ECM in an 86, in dash, pass side foot well area. (As I recall.)
Two screws on case expose MemCal module.
Neck type bowties,... :U

Re: where is it? (LayZ)
I have a fastchip comming. Where is the prom located in a 86 vette?
The long alum strip on the ECU covers the MemCal (Memory Calibration unit). Unscrew it; push off the two end clips holding the MemCal (the blue thing). Push the new one in. Reconnect harnesses (leave ECU dangling); take for test ride.
Re-assemble when satisfied with testing. The second and later times you do it, you can get away with stealing your wife/mom/girlfriends' bathroom mirror, and just kneel next to the seat looking up with the mirror and take it out.
After 10 - 12 times, you'll have it down to less than 5 minutes, all told. :crazy:
