I’ve only been running 30A / 50pA because that’s all the ebike can take based on the battery & phase wire gauge. I’m planning a P26A battery build and an upgraded motor, but that’s a few months out.
The 5.2 hacked firmware should perform the same as the 5.2 stock firmware. I kept all the firmware limits the original one had. I could compile a no limit firmware if you want, but if you are running into over current faults there are other things to try first.
