Daytona Twin Tech 17401 TCFI Gen 4 EFI Controller

Daytona Twin Tec TCFI Gen 4 Auto Tune fuel injection controller is fully programmable plug in replacement for the 36 pin Delphi controller with J1850 data bus.

The Daytona Twin Tech 17401 TCFI Gen 4 EFI Controller is designed for fuel-injection control applications on 2007–2013 Harley-Davidson XL models. It includes a billet aluminum housing with a black finish, a 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 exhaust pipes.

The controller quickly auto-tunes fuel curves for the front and rear cylinders on a dyno or during on-road operation. Its Alpha-N fuel control is designed to address issues associated with long-duration, high-overlap camshafts. Windows software supports custom programming and data analysis, while full support for the J1850 data bus enables communications with the turn signal/security module and instrument cluster.

This Daytona Twin Tech 17401 EFI controller is not legal for sale or use in California or on pollution-controlled vehicles.
