Daytona Twin Tech TCFI Gen 4 EFI Controller 17400

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 TCFI Gen 4 EFI Controller, part number 17400, includes a plug-in fuel injection controller housed in billet aluminum with a black finish. It features 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 can quickly auto-tune fuel curves for front and rear cylinders on a dyno or during on-road use. Alpha-N fuel control is designed to address fuel-control challenges associated with long-duration, high-overlap camshafts. Windows software supports custom programming and data analysis.

Full support for the J1850 data bus enables communication with the turn signal and security module and the instrument cluster. This controller fits 2001–2010 Harley-Davidson FXST models. Accessory items include the 32-3045 USB Interface Cable and 34-1188 EFI Intake Manifold Flange Set Chrome. Not legal for sale or use in California or on pollution-controlled vehicles.
