Just finished reading the Predator Manual (again).

It states "do not perform any functions with the engine running, except for obtaining live data"

I can see where you cannot install a Tune or otherwise try to program the ECM with the engine running.

My question is, can you RESET the DTC Codes with the engine running (while driving) with the Predator?

I've done it with no problems. I had a P1093 (long time ago) while driving and reset it on the fly with the predator. I reset P0101's all the time with it while driving just because I don't like the CEL.
