Ah, I see. You meant timing the sensor sweeps. I thought you meant ignition timing. My bad.
If you followed the TSRM procedure (and it sounds like you did) I'd be very surprised if you got more than around 1 sweep per second. If so that'd be the first sensor I've ever seen do it. Too bad your model Fluke doesn't measure frequency.
Have Cuel check the sensor's average voltage and not just the sweep count. All the better if he has a scope. Average voltage should be 450 mv if measuring OX or 2.5 volts if using Vf with the diag block jumped. The waveform should be clean with no hash. Have him look at injection duration too if he can. Make sure it's opposite O2. It's the only real way to know if the sensor is in command. If you do that let us know what injection duration was in milliseconds at 2500 rpm
Course, it'll probably turn out to be something much simpler. It usually is.
