For me it seems to oscillate more when the battery struggles to deliver enough current, and lower gears, higher rpm tend to behave a little better in that case. The controller also seems pretty bad at dialing back power when voltage is lower (this is something the CA does very well) and my BMS sometimes shut down due to single cell low when I push it.n2mb said:Has anyone gotten the throttle to work well on the stock 14s controller? It is terrible, even with the latest firmware. Super slow and when you hit the throttle from a stop, the motor oscillates and then shuts down. On PAS it is fine. I can't understand why a simple throttle control could be so hard! It's unbelievable.
Also, has anyone fixed the chain ring wobble? I tried tightening the crank, but it still wobbles when you pedal or freewheel the pedals.
My chainring also wobbles very slightly but its barely noticable (a common problem for all these setups, Tangent included, as far as I have seen). I just keep an eye on it, so it doesn't get any worse.
Good point. I'm using a 14s4p 30q battery. Luna wolf. Should be good for 80A peak.
It doesn't oscillate when using PAS, with the same hard start. Only on throttle...
Hm well I haven't tried PAS, but I know a 30q 4p battery will have to struggle to deliver 2000w if below 50-75% SoC. Try running lower gears, let it rev more, see if it does anything to help.
Yeah, this was at 85 - 90% SoC. Lower gears are better, but still bad. I've tried to pick a mid-range gear and run it single speed on the road, so I don't have to shift and I get the best chain line. It's a gear that does about 30 mph on the flats.
I think there is something wrong with their phase / power limiting algorithm that only comes up on throttle and not with the PAS.
