G20 Van with RV Cam no power on acceleration, where to start?

Thanks Dave! I have read through the documents and have my wire installed in the ECM for the data logging and updated the BIN by changing the EGR as described. Waiting on the Sensor\gauges to arrive. I plan on leaving the original 3 wire O2 sensor connected, as that is what runs the spark advance, unless there is a reason to remove it.

Tuning with WBO2 will still require using the original factory 1 Wire or 3 Wire O2 sensor.

WBO2 is basically a measuring tool, like an engine compression tester . . . very useful tools.
