Hi guys, I am working on a trike conversion for my wife who has some orthopedic issues and could use some hill assist. Have ezee hub motor, CA 3.1 and phaserunner, and sempu torque sensor. Having some random issues with the human watts being detected as negative and then as I pedal harder going positive. Suspect the sempu (already had an issue where the right side bb cup was threaded wrong, was right hand instead of left) but not sure maybe it is the ca. Earlier was getting pretty consistent human watts readings but no motor assist, and then after some help from the Grin guys the motor started working but was 100% as soon as torque was detected, as in as soon as you pedaled you would get turbo boost and quickly be going 15-18 mph. Which is awesome fun, but for her needs I need assist not turbo boost
It seemed like the CA was acting random earlier and after a settings change needed to be rebooted to take effect, maybe this is normal idk. So to sum up, had no action, then had full throttle as soon as motor engaged, then while troubleshooting that had no motor assist or random motor assist that was finally proportional but not consistent. Wondering if CA needs to be factory defaulted like it's corrupted or something. I found some old threads where the sempu is referenced as a one wire situation so I wonder about the default, but when I choose one wire I get no human watts reading in CA. Here are the pas settings from the CA:
Some pics of the settings and trike for fun. Also in case it interests anyone custom fab on the grin torque arm to fit the trike, welded with stainless wire and tri-mix gas I had from various car exhaust projects and etc.
