I used it with mainly with stock (17.5) to limited mod (10.5). I didn't have any problems with the motors as long as it was in sensored mode. With out the cable attached it would cog on start up.

When in sensored mode I really liked it. Cheat mode is nice for the slower motors. Allowing you to set the timing advance to kick in at a set rpm. Basically allowing you to keep the torque for take off and then advancing the timing for top end.
