OK, I have a logging solution now and can plot 2 properties at the same time. If I'm really searching for knock I record Ignition Timing Advance vs. what, Engine RPM? Air Flow Rate from MAF?
Anyone? Thanks! -------------------- ... she likes bein' forced ...

I am guessing that you do not have knock volts from the knock sensor?
If you were looking at timing and fuel I would think that you would be looking for timing retard and the addition of fuel. Ign Timing Advance might get you the timing variance but do you have some sort of fuel trim that you can log? -------------------- Fast & Furious on the outside...DSM under the hood!!!
