so no, the ECU if it has one, won't do squat to the timing. I know I can retard the timing to help prevent ping, but that kind of counteracts the reason for increasing the compression.
I can actually get some pretty significant increases in compression... the head gasket I'm having made will increase the engine compression over .7 pts (from 8.2 to 8.9:1). I could theoretically go as high as 9.1:1, but I fear excessive mechanical interference if I were to do so.
