Years ago AA solved the pinging problem on my e36M. Great guys, especially Karl (is he still there?), who did it must have been 15 dyno pulls to get their software right. The car ran sweet after that. I also had their stage 1 software in my e46M, which never pinged during 11 years of ownership. With the e92M I have Dinan stage 1 -- which a Dinan engineer claimed had zero to do with the pinging.
You make a good point about ambient temperature. The e92 pinged in the FL heat and humidity before I moved to VA. No sign of it down here since May of last year. But I still think my problem was a bad tank of Shell 93.
