Tuning Summary:
Installing an HMF exhaust or making other vehicle modifications typically requires specific tuning to accommodate these changes. Unlike a lot of aftermarket companies, HMF tests every vehicle and determines if tuning is required and beneficial. By doing this we can develop application specific tuning thus simplifying the tuning process with pre-programmed tuners and jet kits.
For older machines using a carburetor to meter fuel delivery, HMF has tested and developed Basic Jet Kits to easily accomplish the necessary tuning, compliment our HMF exhaust, and maintain the same reliability compared to stock.
Most modern machines are fuel injected, utilizing a series of sensors and injectors to control fuel delivery. For some this may seem intimidating to tune, but the beauty of testing each and every vehicle we work on means that we can do all the hard work ahead of time and offer tuning that is pre-programmed for the machine. At that point, tuning your machine with an HMF exhaust installed is as simple as installing the tuner, and you’re done. No going to a dyno, reading spark plugs for rich or lean fuel mixture, modifying complex carburetion systems, getting covered in fuel, etc. just plug in a few connections and get back to riding!
This is our tried and true basic tuning solution. All Optimizers come pre-programmed accounting for the HMF exhaust installed on the machine. Installation is as simple as connecting the wiring harness between the fuel injector and factory wiring harness. Connect the ground for the Optimizer to a good ground and you’re essentially done.
The key benefits of the HMF Optimizer are low cost, easy installation, and the ability to make changes to the tuning on the fly without the need for a computer. The downside is that any change to the tuning of the Optimizer will affect a large portion of the overall tune since it primarily operates with 3 defined load ranges.
Is Tuning Really Needed?
Not all machines require tuning and we’ll tell you if it is needed or not. Carbureted and older fuel injected machines do not automatically compensate for the added airflow through the engine when an aftermarket exhaust is installed. Even many currently produced fuel injected machines do not incorporate the needed sensors to actively compensate for changing conditions or modifications.
We test and tune all the machines we offer exhausts for. That way, we can verify if a machine will run with a safe air-fuel ratio without a tuner. If a machine runs lean during our testing, we explore tuning options and try to develop easy solutions to fuel tuning to complement our exhaust. Failure to tune the engine can cause excessive damage to the exhaust system and engine while voiding the warranty on your exhaust and possibly on your machine
