What readings does the CA show you for all the different screens when you reach the max speed without pedalling?
Which limit flags are capitalized when you reach the max speed without pedalling?
If there are no limit flags at that max speed, the CA settings are not involved as it isn't limiting anything, and it is then up to the controller and motor and battery. ****
What are all your present settings, in both the CA and the PR?
If the PR settings aren't maxed out, then doing that might help depending on what the thing is that is keeping your speed low.
If the PR is maxed out, then the motor may simply have a slower winding than your previous motor and so spin slower. What speed does this motor spin at, without any load (wheel off ground)? What speed did your old motor spin at, same conditions?
**** well, it's possible the throttle output isn't high enough to match the controller's throttle needs. You can change that in either the CA or the PR so that the min and max throttles are matched. If the controller doesn't get enough throttle to get full power, it could cause insufficient speed...but for this to be the case, the PR would have to be only using the same or less battery current than your previous system, for the previous one to be faster. (and/or the motor winding is too slow, and/or the battery is so heavily loaded it is sagging in voltage so much there just isn't enough power).
