H&D Cycles has the latest in DynoJet_® and WinPEP 7 Technology, real time air fuel ratio, test gas for proper o2 sensor calibration, the latest training and knowledge of the TTS MASTERTUNER with 02 Sensor Data, TECHNO RESEARCH DIRECT LINK, SERT, SEPST and POWERVISION T-MAX, and more.

It’s not just a download with a couple of 100% Throttle Position runs that make up a tune. 

Here at H&D Cycles we adjust and synchronize the Volumetric Efficiency (VE) tables to your new engine configuration.  We use and adjust all 20 tables in the TTS MASTERTUNE, if necessary, to eliminate decel popping, detonation (pinging), acceleration, and of course, Air Fuel Ratio (AFR) and timing tables for optimum performance. 

H&D Cycles spared no cost to equip our technicians with the latest equipment and training to bring them to the “next level” to service your tuning needs. 

It’s a long, painstaking process to completely remap your fuel injection system correctly…

but, when it’s done right, 

your bike will run cooler and smoother with more power throughout the complete RPM range, not just at 100% Throttle Position. 

A map is made just for your engine configuration and exhaust system – it is a complete custom map that is “finger printed” to your bike alone.  Each and every Harley-Davidson engine has its own personality and characteristics, and needs its own EFI map to let it run at optimum performance.

Experience what a custom made map from H&D Cycles feels like.  Let us assure you that your investment and experience with our tuning ability will not be disappointing…You will be impressed!!

Things to know before having your bike tuned:
*Come with a full tank of  the gas you usually run. In our area i recomend 93 octane ethanol due to its octane rating and availability. No Additives please.
* Tuning should not be used to cover up mechanical or electrical or fuel issues.
* The bike should in proper maintance. If it has not been recently serviced we can do that before we tune.
* Tires should be in good shape.
* Stock plugs and wires( for proper spark knock detonation/ ion sensing)
* On larger motors you should have the proper clutch and driveline componetsfor the application.
