Hi Greg - are you sure about STunlocker not supporting US Class 3? This post says differently: https://www.emtbforums.com/threads/stunlocker-ex-shimano-steps-unlocker-android-windows-app-for-derestriction-market-change-and-etc.4935/post-634845.
Are there any differences between the features offered by EMax and STUnlocker for tuning Shimano EP801 motors? I want to change the motor to US Class 3 and continue using Fine Tune mode.
