The MPS ECU Shifter Kill is the new high tech innovative way to kill the motor to air shift. MPS reprograms your factory Suzuki ECU to allow it to kill both the fuel and ignition between shifts. It features a small delay in activation to effectively load the shifter before the kill event occurs. This works particularly well for dry nitrous bikes to eliminate the pop between gears and does not trigger the FI light. The ECU Shifter Kill comes complete with a MPS ECU Kill Harness that features total plug and play compatibility and requires absolutely no cutting or splicing. It also has a toggle switch to select standard horn operation or air shifter activation with your horn button. It can be installed easily in just a few minutes. The ECU is reprogrammed with 60ms kill time. Any kill time between 30ms and 120ms in 10ms increments can be programmed. ECU turnaround time is same day. As a bonus we will raise the rev limit, remove the 186 MPH speed limiter, and remove the timing retard in low gear.
