However if i also reduce the L value my transition becomes more managable. Not perfect but with L at 120uH and R at 48mohm i get better pullout and quite good power. Car is actually fun even with my limited Kokam battery.
At one point Lebowski was recommending an L/R ratio of 1e-3, I don't think that is still current but the point I am making is that the suggestion at the time was to increase R to achieve that not reduce L. It is established that the controller can not measure stator resistance perfectly so we know we must increase the value of R to get ideal results. So rather than reducing L maybe you could try increasing R to approach the ideal L/R time constant but leave L at its measured value. I find that if you increase R past a certain point the field weakening is affected so it is a matter of "suck it and see" trial and error. Have you reduced menu N) sub h) to the default 1000? I really think 35,000 cycles is not helping.
Are you able to recalibrate the RLS encoder without removing the motor from the car? If so that might be a good idea to see if you can eliminate the large HALL sensor offset.
