I have read that you can do all of these with the power fc:
Duty Cycle, Ignition Timing, Airflow Meter Output Voltage, Engine RPM, Road Speed, Boost Pressure, Knock Sensor Output, Coolant Temp, Intake Air Temp, and Battery Voltage.

The problem is that I dont know what some of these are. Obviously I know engine Rpm and other basic things, but does anybody know a website that has definitions of some of these things and what they do? Thanks.

 

If you read the "F" section of the Mazda RX-7 Maintenance Manual, it is a good starting place.

 

thanks
