The Head Quarters ProTuner combines all the functionality of the Screamin Eagle Race Tuner and Super Tuner, TTS Master Tuner or Direct Link with the dependability of utilizing your factory ECM, and the latest technology available for Automatic EFI Fuel System management. Not to mention ease of use...comes custom programmed for high performance builds, no complex setup procedures, no guesswork, and best of all, no expensive dyno fees.

It's simple...load a map into your factory ECM with the Screamin Eagle Race Tuner or Super Tuner, TTS or Direct Link and  hook up the Head Quarters ProTuner, go ride...it does the rest! Minor timing adjustments may be required depending on your build which is done with your Race Tuner or Super Tuner.

No matter how you ride, the Head Quarters ProTuner EFI Fuel System Controller learns and remembers your riding style while constantly monitoring and correcting your A/F ratio as needed...up 500 times per second!

If your bike is already tuned with a Screamin Eagle Race Tuner, Super Tuner, TTS or Direct Link but you want the comfort of automatic fuel system management, then the ProTuner will work for you...even if your engine package didn't come from Head Quarters. After the ProTuner calibrates to your engine, riding style, weight, and conditions, minor timing adjustments may be necessary to maximize performance which can easily be done with your Race Tuner.
