53-685 1997-1998 Harley-Davidson Touring models with Evo engine.
The new Dyna Fuel Injection Controller is a plug in module that
offers 3 user selectable base fuel curves that are designed to improve
engine operation and can be modified to suit a wide variety of
modifications. These adjustments are made via 3 potentiometers
that adjust the fuel curve in the proper ranges for the application.
Fuel mixture can be enriched or leaned as required. The Dyna FI
Controller uses the factory connectors for easy installation and there
is no PC required for tuning or adjusting the fuel curves. There are no
modifications to the stock ECU and removing the Dyna FI controller
returns the vehicle to the factory configuration.
