MPS Electronic Engine Kills

The new generation MPS Air Shifter Electronic Engine Kills have several new features:

MPS Gen 2 Electric Engine Kill


The Sport Bike Electronic Engine Kills (1-0263-1) were designed specifically for sequential firing 4 coil ignition systems like those found on most sport bikes today. The Original Electronic Engine Kill (1-0211) was designed in 1987 for drag race bikes (2 coil) to replace the unreliable air kill. The kill time adjustment is set through the access hole in the top cover. Set time is from 50 milliseconds to 100 milliseconds. We invented the Electronic Engine Kill so we can offer our exclusive, no hassle, free repair or replacement lifetime warranty. Be sure to ask about that when buying copycat versions of our products. Custom wiring harnesses with a shifter/horn toggle switch are available as an option for some specific bikes to make wiring your MPS shifter a snap.


02 and Up Hayabusa ECU Shift Kill

MPS ECU HarnessThe 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.
