How are you guys getting your 1/8th xeruns to work on 2s lipos?

Do u have to change the cell detection to 2s using a 4s (whatever voltage comes stock) possibly?

I have the 150a and 4 pole tenshock 4000 sc401 non sensored

I'm at 0 timing, low punch and tried to set it to 2s

All on my friends LCD box

I get undriveable glitching and it jolts for a few seconds if I even slightly tap the throttle. I've tried calibrating to the transmitter several times
