This speed control box works with XCT generation 2 regen controllers. Just rotate the dials to adjust your top speed/acceleration and regen. Put it on the dash for easy access or hide it under the seat. First generation XCT controllers do not have the receiving plug to work with this.
FN2-XCT provides interactive top Speed+Acceleration and Regen control for mild street to wild performance
Speed and Acceleration can be linked or separated in program software
