The lowest possible current ramp rate on your controller is already like 2000 amps/second or something, so I think the problem is somewhere else.
Hi Paul
Its in the car and working so I'm just going to enjoy the lovely autumn weather

I'll think about fixing it later

I haven't got any actual numbers about its ramp time, it just feels like its getting into its stride at about 50Kph

I wonder if the advanced brush timing is doing it - so the current is constant but I get more torque as the revs increase ....
