I pulled the ecm from my 1989 iroc with a tpi and vin 8. I found out it has a cardone ecu with a delco APYN 3496 chip. I am wanting to go back factory with the ecm and prom but I am having a hard time finding either online. Does anyone know what part number I should be looking for or who would have these in stock.
Thanks

 

1227165 is the factory service number. That is the correct memcal for your car.

 

Thanks for info I found that number by reading threads and I have searched all day including the delco and gm parts website they either say not found or I can not find the ecm available anywhere. Do you have any suggestions or know who might carry the ecm?
Thanks

 

If your wanting one with a sticker different than your remanufactured one look on eBay or post in the classifieds wanted section.

 

A newer number for the '7165 ECM: 16198259

Note that the cardone ECM is an OEM GM ECM.

Ok thanks for the info everyone been trying to read the threads and seen alot that said cardone bad get an oem one so basically the one I have is OK
thanks

 

I just now saw this string and wanted to add my two cents. I was able to get an ACDelco GM remanufactured ECM from my Chevy parts dealer just last month, so I know that they're out there! Good luck!
