WHAT DO YOU EXPECT FROM THE CHANGES IN YOUR CONTROLLER? Top speed, charging characteristics etc. It would be nice to have explanations of what each setting does. Is there a pamphlet for that? what increase in performance did D&D give you. Is the GE T4 controller the stock one.

There is a booklet with the software. I do not know the best settings for the Motor. In my case I am not after speed but distance and less stress on the motor. I wanted to see the settings as I bought the GEM a few weeks ago and knew that the battery was not setup correctly and wanted to see what else was not.

Not sure what your settings will do but it would be awesome if we “as a community” could come up with a set of numbers that would give users the best results.

Example: Performance Tune and a High Milage time

Booklet name. Is it a programming book to change perameters?

I ordered the software , it came with cable and software on cd The manual for the controller is on the cd and gives a generic description for each parameter. Took me a while to figure out the cable and the jumper.

Thanks. I ordered that program several years ago but never got into it. Reviewed it this week and found a lot of information. Mine is for a T2 controller. Does anyone have a recommendation for increase of speed. Looks like elimination of max speed parameters. Regards

I noticed my battery charge indicator did not seem to work correctly. I changed #15 to 76 volts as a fully charged battery wet battery is 12.6 volts. I now indicates on the dash that the battery is discharging.
