The Dyno Dip

[Frank Orozco]

You're not wrong Jon, IIRC, Kojima has told us that the knock sensor is a simple piezo microphone that can not detect knock above 4,000 RPM.

Maybe the new Spec-v's use a more sophisticated type of knock sensor.

The O2 sensor is entirely ignored at WOT, and I'm positive about that much. Crank your timing up to 20* some time, run a tank of 87o through it, and see what happens. ;)
