Thanks for jumping in Bill. Always like to hear your advice. From what you said some esc's can set the timing ahead without a sensor wire and others will only do it with a sensor wire. The Castle programming card seems to imply that their non-sensored esc's can do it. Best way to tell I guess is try different settings, run the car for 5 laps, and check the motor temp. If temp changes then the esc is probably changing the timing.
