Guhl Motors is proud to announce the unveiling of brand new, cutting edge, money-saving fuel injection technology*. After two years of intensive research and developement we now have the capability to reprogram selected stock ECU's without making any physical modifications. This means no cutting into the ECU, no adding unreliable resistors, and no more buying external add-on tuning components (ie: Power Commander or racing ECU). Essentially we are programming as the engine manufacturer does. This is the first time in history that this has been possible, both in the micro racing and motorcycle communities.

Here are just a few of the advantages of using GUTS (Guhl Universal Tuning System):


Replaces expensive add-on units (ie: Power Commander, Rapid Bike, racing ECU, etc.)
No physical ECU modification necessary, we will not cut into your ECU to perform the GUTS service
No unreliable resistors required for anti-theft and tipover sensors
Raise and lower rev limits without changing the fuel/ignition curves or re-dynoing
Tune stock ECU's as the factory does with unsurpassed control and accuracy
Failure rates decrease due to fewer electrical connections
Entire fueling system will be lighter weight with less connectors, modules, wiring, etc.
Greatly reduces installation time and effort with new systems and engine changes
Customizable tuning capabilites


More information on these groundbreaking advances including pricing will be released in the weeks to come. We are also aggressively working toward adding additional engine models and capabilities.
