Re: Can anyone verify this ECM part number?
I ordered an ECM from P & G chevy last year, p/n 16163993. I just went to their site, partszoneonline.com, and ran that p/n and it came back NLA. I then did a search of their catalog using 1992 ZR-1 ECM and the catalog says that there is an ECM but it does not give the p/n. I would suggest calling their parts hot line...they were very helpful to me when I bought a replacement ECM for my 90. They tracked the p/n thru a few changes and finally discovered the 90 ECM's were NLA and that the p/n 16163993 was the replacement. I believe they told me that the ECM I was buying was for a later yr ZR-1 but I don't remember which later yr....maybe 92 & up???
