This is my first build, so I expect I've configured something incorrectly, though I haven't figured out what yet.
In short, I have a CA3 connected to a baserunner connected to a Bafang G60. When the wheel is on the ground/under load, the speed is incorrectly detected as being over 100 - 300MPH. Once it gets up to speed, it seems to settle down to a more reasonable number, but I haven't had a chance to compare it to a GPS speedo yet.
If I put the bike on a hoist and engage the throttle, this doesn't happen. I've gone through all of the baserunner and CA settings and can't find an obvious explanation for why this is happening, so I'm hoping smarter people than me will have some ideas on what I can do to troubleshoot this. For the record, the speedo poles is set to 6.
In case it's relevant, I was getting virtually zero power from the motor when it was under load initially, but I believe that was caused by a misconfigured current limit (decimal in the wrong position) and doesn't seem to be happening now. However, it does take a few seconds for the bike to get up to speed and seems slow to respond to throttle/PAS input.
