Daytona Twin Tech 17600 TCFI Gen 5 EFI Controller

Daytona Twin Tec TCFI Gen 5 Auto Tune fuel injection controller is fully programmable plug in replacement for the 36 pin controller with CAN data bus.

The Daytona Twin Tech 17600 TCFI Gen 5 EFI Controller is designed to address tuning requirements for highly modified engines. It includes a USB interface for PC link, a WEGO IIId dual-channel wide-band exhaust gas oxygen sensor interface, two Bosch LSU 4.2 wide-band exhaust gas oxygen sensors, and two 18 x 1.5 mm weld nuts for the exhaust pipe.

The controller continuously auto-tunes fuel curves for the front and rear cylinders under riding conditions. Its robust alpha-N fuel control helps address tuning challenges associated with long-duration, high-overlap camshafts, while data flash memory stores up to 60 minutes of operating data. Idle air control, including idle RPM and cold-start characteristics, is fully programmable.

Powerful Windows software supports custom programming, extended data logging, and diagnostics. The controller also facilitates the use of aftermarket throttle bodies with higher airflow. This Daytona Twin Tech 17600 unit fits 2012–2021 Harley-Davidson FXST models. Not legal for sale or use in California or on pollution-controlled vehicles.
