Harley Davidson Motorcycles Fi-1040Hp Tfi Electronic Jet Kit

The Techlusion Fuel Injection (TFI) control box is a new standard in fuel injection adjustment. Manufactured by Mark Dobeck the founder of Dynojet. This system is different in its method of adjustment by dealing directly with the fuel injection signal after it leaves the factory ECU. It adjusts your fuel requirements without tricking sensors or modifying the factory settings, which can limit the ECU's effectiveness at compensating for changing altitude or weather conditions.

The digital circuitry construction allows a specific range of adjustment of the fuel delivery curve int he areas that most effect drivability and performance.
