Alright another round of tests I was briefly happy for a sec. I bumped the amps back up to 65A front for all these tests.
TL;DR I traded one overcurrent for another scarier one. Or maybe the second one always existed but I hadn’t gotten to it yet.
I tried dropping the detection time constant as mentioned here by @Fatglottis:
But unfortunately that didn’t help.
Next I tried traction control mentioned by @glyphiks and started at 7500 diff ERPM mentioned in @Titoxd1000 post. And wow I was surprised that actually helped. Today I did also notice the wheel spin happens toe side more than heel side so traction control really helped. I dropped it to 5000 ERPM diff which further reduced the wheel spin.
I was at this point able to start hitting sub 2 sec launches, was feeling good.
Then the best time yet and fuuuuuuck I faulted under load at 20-25 mph.
You can see above where the last fault happens at ~74k RPM.
I tried dropping the amps to 60A but I don’t have to tell you my confidence was a bit shattered and I just didn’t have it in me anymore today. Times went back to shit.
At this point idk. Two more things I’m thinking of trying. One try going, sensorless and two replace the front motors with my old 225KV ones. I guess third option is to send them in to @YUTW123 but damn AVS around the corner.
