Don Tuner

Discover the most advanced Harley mapping tool on the market

Who does not know it?

You install a new air filter and exhaust system on the customer’s vehicle and suddenly the motorcycle no longer runs smoothly. The original calibration does not fit. The consequences of this are lean jerking and much too high engine temperatures.

For this, the Don Tuner is the perfect solution. It offers maps for bikes with modified air filter as well as exhaust systems or camshafts, but also for stock configuration. The software optimizes power, torque and engine running and protects against overheating due to lean running. Don Performance offers a 30 day money back guarantee on the map and is specifically designed for Canbus controlled models with Twin Cam, Sportster and Milwaukee-Eight engines. Tuning is carried out by authorized dealers and can be reset to the standard configuration at any time.
