I just installed an all Grin axle front hub and Baserunner. It replaced a G311. I have a CA3 ver 3.15. I have Aux A configured for PAS level. No torque sensor, just magnets. Power Lim 500w. Pot set to 70w with a 6 scale. The issue I'm trying to solve is that when I start pedaling the power output briefly surges to between 150w-250w before settling to the 70w plus scaling set on the pot.
