The HMF Optimizer is a Fuel-Injection Controller that has been pre-programmed to work with your machine with the proper tuning specifications for your HMF exhaust. You must retune your machine when adding an aftermarket exhaust system so the correct fuel mixture is delivered to prevent costly engine repairs.
- Easy to install, simply plugs into the existing wiring harness
- Make tuning adjustments similar to tuning a carburetor
- No Computer or Dyno needed to make adjustments
- Water and shock resistent
Note: Not tuning your machine will void the warranty of your HMF exhaust.
