I’ve invested in equipment and software from TechnoResearch to be able to do everything Harley’s “Digital Technician” can do and more. It’s an all-inclusive system that allows us to do all the Diagnostics AND Flash Tuning. What does this mean to you???  I can tune your fuel injected Harley using wide-band O2 sensors.  Each cylinder is tuned individually for both air fuel ratio and timing  I can program new ECM’s, keyfobs, and security modules, bleed and purge ABS braking systems, calibrate (flash) the new audio systems for upgrades, and more. You no longer have any reason to subject yourself to the dealer’s service department!  YES, THIS INCLUDES ALL THE NEW HARLEY-DAVIDSON MODELS!

Under the Magnuson-Moss Act, aftermarket equipment which improves performance does not void a vehicle manufacturer’s original warranty.

A dealer must prove that aftermarket equipment caused the need for repairs before they can deny warranty coverage on that basis. What’s more, dealers cannot void your warranty themselves, only the manufacturer can.  Dealers can only make suggestions to the manufacturer.  Dealers cannot refuse to perform warranty services unless and until the manufacturer makes a ruling on it.  To challenge a dealer’s claim about voiding warranties, ask them to put it in writing. If they refuse to give you a written statement, this is a violation of Federal law. The Federal Trade Commission , which administers the Magnuson-Moss Act, monitors compliance with warranty issues. Direct your dealer complaints to the FTC at (202) 326-3128.
