Has anyone calibrated or made adjustments to an ebike TMM4 torque sensor? My 2012 Stromer ST1 runs well but I noticed that the sensor plate is bent inwards at the derailleur hanger also cracked and rear derailleur damaged. Replaced plate and derailleur but PAS became sluggish. Reinstalled original parts and back to normal.

I found this with a quick google search. Perhaps the documents will be helpful.
