I never got any pinging with the stock computer, but I did get it with
the MP PCM, even with 92-93 octane. A 180 degree thermostat fixed the
problem for me. I also make sure to never fill up at a Coastal station as
the local one would cause pinging every time. I almost exclusively go to
Mobil stations. (Yeah, it probably all comes off the same truck, but I've
had good luck with Mobil so far.) :-)
