Short version: What EEPROM p/n to burn the zz4 calibration on?

Long Version:
The '84 firbird that I picked up the guy was building a ZZ4 'clone' engine (350, .030 over, corvette heads, mid-rise GMPP intake, crane cam, roller rockers, etc.) Since I'm guessing that the computer is still stock I thought I'd start with the ZZ4 ESC calibration chip to get a baseline and then tune from there... The big question I had is getting chips for the old ECM to tune - the factory chips were a ROM it seems (N82S181), there was talk of UV eraseable eprom that I found but then doing some research on the web I found reference to the 2816 EEPROM as compatible with the N82S181 chip that GM installed - has anyone used one of those successfully in a CCC computer?

I have the XDF and the BIN file and have looked it over and tweaked the timing maps to where I think the engine would run good and be a little safe initially (based upon experience with carb'd engines and mechanical distributors) so if I did it right I'm just needing a chip to burn it on and test it out!

 

Are you sure its not a 2532 ?

The 2532 was a UV eraseable PROM, the 2816 is Electronically eraseable PROM - in other words it works more like modern flash memory - the other one would require a UV Eraser that I don't own and and since I already have the programmer stuck in the closet from when I had an '89 corvette I was trying to avoid buying a UV Eraser just to do a couple of chip burns for this 'toy'
