I have a V3 Cycle Analyst with V4 Baserunner_Z9 running an SX1 front hub motor, 48 V battery. 12 pole PAS only, no throttle. The Baserunner settings are the default just downloaded again from Grin. It all works fine except that riding uphill at 10 to 12 mph with 500 to 700 W power the motor surges. On the diagnostic screen I see that the S (speed) flag is flashing on with the surges, every few seconds. I do not see this happening at lower speeds (6-8 mph on the same hill at same power), nor at high speed (20-25 mph on flatter roads). Grin recommended checking the max speed setting at the Baserunner (it is set at 99), and to check the speed settings and gains on the CA, which are listed below:
Max speed = 28 mph
Start speed = 0
Max no pedal = 99
Regen disabled
PSGain = 2.01 V/mph
IntSGain = 100
DSGain = 600
The max speed should be OK, and I tried upping it to 500 with no change. Can anyone please advise if the other settings look right, and recommend any tweaks?
