Fitment Notes & Exceptions

This system is designed to work on an OEM throttle body, part # 27300122 or aftermarket equivalent on an M8 engine with crank position sensor ONLY.

Also requires:

  • A fuel tank with a Big Twin or XL fuel pump or insert a fuel pump into your existing tank.
  • A non-CAN/Bus fuel gauge or speedometer with a built-in fuel gauge that can connect/read the fuel sending unit from your pump for a proper fuel reading.
  • OEM style ignition coil 31600017
  • OEM speed sensor 74402-05 B

This system is only for engine management. If you are building a custom bike, you will need to purchase a complete bike wiring harness for all other normal functions like lighting, switches, gauges, etc.

This system will not provide cruise control.

Once you are ready to tune your ECM, direct all calls or emails directly to Thundermax as they will service the ECM as they do for any of there other ECM kits.
