The NXT stock comes with ramping and semi only, if you want to set up ramping, open the grips push and hold the power button, quickly push the lower board button untill it double beeps, that should set it to rebound mode 5, then hold the trigger and push the lower board button untill you reach your required ramp speed, i think the ramp activation is 5 bps. I would check zdspb.com for the exact ramp speed you need
