I chased my tail with this as well. Thought I put a good auto zone sensor in but once I went to the dealer and put a GM sensor in it went away!!!

They even price matched on line...

I tried that at the dealership by my house, the same one I bought my GTO from, and they wouldn't budge. Haven't gone back since then. Stingy bastards.

make sure you have the memcal on the chip carrier...

I think what Eric is trying to verify is what number is on the squishy part of the memcal

Eric Sy GN said:
Any memcal that has the original Syty knock control circuitry will work. You can tell by the part # on the little circuit board. The 2nd and 3rd digit will be "14". (At least from the research I've done.)

The actual eprom chip (Pitbull, KB, etc), doesn't matter at all, since it is being bypassed completely.
