1992 zr-1 datamaster scan help.
I have a 1992 zr1 that is stock except for a Marc Haibeck prom. I was wondering if any one would take a look at the datamaster scan that I took. Just want to see if anyone notices anything out of the ordinary.
The reason I took the scan is under moderate to hard acceleration I get a pinging noise. (detonation) I do have 92 octane gas in it and new plugs. Other than the pinging it seems to run just fine. Thanks for the help.

You should send it to Marc have him look at it and if necessary make changes to the prom…I also have one of his chips in a 91 ZR-1 and had a similar issue, he reprogrammed the timing to stock under 3000rpms took care of it.
