Looks good! Glad I could help you find a good option for your setup! It's a great rack for $110-$150!
Looks like your fit had a couple of inches to spare...ha!
Measure twice, buy once...
Take care, man!
Did you ever free spin the back wheel off the ground with the throttle? I did that and it showed my max speed like 50mph. It didn't occur during a ride.
I doubt one inch matters much...but TIRE + RIM = WHEEL. Mine was 27 in my settings. The part of the WHEEL that touches the pavement is 27.5". So you want to measure those revolutions for accurate distance traveled. It counts how often it goes around X tire circumference = DISTANCE.
I...
I can not answer your questions directly but I can add some observations.
Wheel size should be 27 (I assume you have 27.5 on the Ultra beast).
And it seems you are not using the program with the TORQUE tab? That only matters of course if you are trying to change TORQUE settings.
There is a...
I am uncertain about that (hopefully Clark answers soon).
Do this...read all the current values and take screen shots and/or save the stock configuration file. Look and see what the current setting is you want to change. If the L9 is too low and its at like 10%...then ya...maybe 100% is too...
Here is a link to the file:
https://drive.google.com/file/d/18DCTQoQZ7MHID-rxkPJW6t_q_wPZr-1m/view
inside the folder there will be a .exe called "Controllerst_torque.exe"
use that one...the other file "Controllerst.exe" doesn't have the torque tab.
Also...save your stock settings as a file so you can go back to them if you need to.
Or at least take screen shots of the four programming screens so you have the original values.
Unplug the controller...green cable..five pins...plug the USB cable in to the part of the cable that goes to the motor. Have the battery in it while you do it.
The pins are tiny and bendy so be careful...
Use the arrows to line them up.
Also review the vid I posted.
