I've heard of this, seen it work, but am totally not familiar with it, I understand it can interrogate the Ford ECM.

If you use it to turn off TPMS or a crank relearn will it affect tuning with something like HP Tuners? I used my old SCT tuner just for a crank relearn once after tuning and it locked the ecm so we could not access with HP tuners anymore. Finally figured out we had to use the SCT and return to stock tune and then reload everything with HP tuners.
My car has a Lund tune, but the car did not come with a tuner. I used Forscan to do the crank relearn, and I haven’t noticed any effect on the performance of the car. So I don’t think it changed the tune or reflashed the car since it is a maintenance type function.If you use it to turn off TPMS or a crank relearn will it affect tuning with something like HP Tuners?
