The Votol EM 150 controller that first powered the QS3000 edirtbike, then next moved to the QS2000 edirtbike, is now on the QS1000 edirtbike. The controller has never been programmed by the rs232/pc method by me as it worked quite well on both the QS 3000 & 2000 motors.
Since the QS1000 motor/EM150 controller could be eventually be running at 120 amp, I changed the QS1000 rear sprocket from 48T to 40T. Today the streets has sections of dry pavement and so several 3-4 block run-ups were done.
The CA is not hooked to monitor /change the throttle mapping but it monitors the R-shunt. The CA was set at 99amp max and 8400 watts max.
The first ride was wild — after a fast acceleration the motor reached that warbling RPM cadence where maybe the controller or CV is limiting max motor current, speed or something—fluctuations of sorts? This motor when it was running the EM100 did this same warbling[no limits set], and then would break in to short time period of gaining higher rpm and soon top-out. Not so with the EM 150 powering at full throttle while warbling. It broke out of the straight jacket after the warbling RPM and with acceleration as robust as ever to become a run-away. Dialing the throttle back down did not change the earlier WOT response/action. I turned the key off to stop it.
The throttle response would go to zero when released if you did not go through the warbling RPM phase — maybe up to 33mph. The data gained from 4 rides beyond warbling rpm zone was the workings of the 120 amp controller.
- At about 46 mph I saw the wattage reading of 8600 watts. This max amperage 136.6 was the max stored from 4 speed runs.

After 4 x 1/4 mile runs the motor was not even as warm as my hand zooming to speeds of 47 mph — with still more left.
The going wild throttle response is not desired. Are the limits I set on the CA causing this WOT response?
Paging Amberwolf — any ideas? Perhaps too much gain set in Wgain?
