I?m curious why the choice of Zero on C5 ?max current? compared to the others? The others have something other than zero and jim1 started with 10. What?s your experience with that setting?
It's been quite a while since I did the testing, but as I recall I started with 10 because that's "maximum current value" and doesn't limit the throttle ramp-up. I don't think C5 limits power output except as the throttle is applied from zero - I still pull around 1600w at max power demand.
IIRC, set to 10 it just leapt off the line very harshly with all the power offered by the new controller, so I tried other settings, and for my MiniST2 ended up with a value of 00 for a relatively soft start with multiple increments before hitting maximum. For me, that's much better for pulling away on slippery surfaces or from crowded supermarket parking spaces, stoplights etc. where a sudden leap forward might come to grief. It's up to full power in just 2-3 seconds, so it's not very limiting if I want to scoot away quickly with full throttle. A setting of 01 is similar, but has 2 rampup speeds rather than 3; some may prefer that. Settings of 3-10, as I recall, don't have steps, they just apply that fraction of maximum power during rampup. Hopefully somebody with better recollection will chime in if I'm wrong about the above comments.
Additionally, because of the smallish 20" wheels, the Mini puts more force (same torque, but on a smaller radius) on the road than a Rover for instance, so the effect is magnified.
As usual, YMMV and individual preferences will give the "correct" result with a little experimenting. That's why I created a new column when my settings were changed, so I could refer back to previous values without guessing.
FYI, my DIM setting of 23" for tire diameter was set after comparing the bike's display against GPS while in cruise-control on level surface - it matches almost perfectly; this value might need to be adjusted for different tires, but I think a setting of 20 is always wrong for accurate speed display.
