I've got a CAv3 with the 12-pole PAS (all from em3ev) with a Mac10T
I've set up the torq-pas mode and it great fun to ride long distances without thinking about throttle; just feels like I'm superman
However I noticed one issue:
Normal case:
1. While riding, if I stop pedaling the power ramps down as per CA setting. If I restart pedaling the power ramps up smoothly and all is great.
2. If I'm riding and stop pedaling but the power hasn't ramped to 0 (there's usually an audible click when the motor disengages), and I restart again with less than 1/2 a turn (it might be 1/4 as I can't really tell), then there's a surge of power to the motor for a split second which then dissipates and then it continues as normal
3. This would also happen in the pathological case if one is stopping quickly using the brakes. The power hasn't completely gone but I might rotate the pedals a bit to balance causing a surge. Strongly applying the brakes stops it from crashing.
I thought it might be because having the 12 pole sensor causes the sensor to think I'm doing a really high RPM due to invalid signals, so it could be that. But it's fairly consistent that it's only when the power is coming off and I restart. If I wait till I hear the clank of the motor stopping then start pedaling whether quarter turn or anything then it's fine.
It might be a setting I need to enable?
Anyone seen this and knows how to fix?
