As long as none of the 0.001 to 0.1 values will cause damage to either the motor or the controller then trial and error may be ok. I am assuming that an incorrect time constant will cause the motor to take longer to slow down the rotating flywheel and then accelerate it back up in the opposite direction.
Depending on how quickly the performance degrades as you move away from the ideal value then maybe we could sample at 0.01, 0.02, 0.03 etc. Then test the 10 values between the two best out of the first set of ten tests. That would save having to run the test 100 times.
If the test required a bigger load or if the car had no flywheel then maybe a wheels up test using the momentum of two spinning wheels as the load to test against?
