Increase the amount of regenerative braking going down hills.

With the On-The-Fly Programmer, increasing the amount of regenerative braking will not only put energy back into your battery pack but it will also save wear and tear on your brakes.

Limit the acceleration of the vehicle.

Limit the acceleration of the vehicle to reduce the size of the current peaks drawn from the batteries. This also will lead to an increase in range.
