JFB - Yes, right now, I have access to a "Two Channel" monitor unit, but only have a single sensor, and a single cable.
So the runs were made on alternate days, attempting to duplicate each other. I have to physically move the sensor from one exhaust to the other.
Idle is easy, maintaining a steady RPM on the same stretch of road is pretty do-able. Matching shift points and gas pedal modulation on an acceleration to 70 MPH is impossible.
I agree, I have to read more, and get more familiar with the characteristics of the instrumentation.
