Daytona Twin Tec TCFI Gen III AutoTune Closed Loop EFI ECM System


The Daytona Twin Tec TCFI solves tuning problems with highly modified engines. Competitive “band-aid” products that interface to the Delphi® controller still rely on speed density fuel control. Long duration/high overlap camshafts wreak havoc with manifold pressure - especially at idle and cruise RPM. Speed-density based fuel control simply can’t cope. High-end automotive racing systems use alpha-N (throttle position and RPM based) fuel control. Alpha-N eliminates any dependence on manifold pressure and is unaffected by long duration/high overlap camshafts. The TCFI brings this proven technology to the H-D® marketplace.

The TCFI has the same ignition control as the proven TC88/TC88A Twin Cam ignition systems with fully programmable advance curves. Idle air control including idle RPM and cold start characteristics are also fully programmable. This facilitates the use of throttle bodies modified for higher airflow. The TCFI kit now includes the new WEGO IIID dual channel wide-band exhaust gas oxygen interface that allows auto-tuning during actual on-road riding conditions. The kit includes Bosch LSU 4.2 wide-band sensors for both front and rear cylinders. The user programs a table with the desired air/fuel ratios - the system then does the rest.

New H-D® motorcycles use the SAE J1850 data bus for communications between the engine control module (TCFI), instrument cluster, turn signal/security module (TSM/TSSM), and diagnostic scan tools. The third generation TCFI fully supports this new J1850 data bus including the use of the HD ® scan tool to read sensor data and clear diagnostic codes. The TCFI also has built-in data logging that stores data for the last 60 minutes of operation at 10 samples/second. A USB interface and Windows compatible software allow the use of a laptop PC for programming and data analysis. The USB interface plugs into the existing H-D® diagnostic connector on the motorcycle wiring harness.

• Simultaneously auto-tune fuel curves for front and rear cylinders under actual riding conditions with new WEGO IIID dual channel wide-band oxygen sensor interface
• Fully programmable plug-in replacement for 36 pin Delphi® controller
• Robust alpha-N (throttle position and RPM based) fuel control eliminates problems with long duration/high overlap camshafts
• Powerful Windows software for custom programming and data analysis
• Full support for J1850 data bus used for communications with turn signal/security module (TSM/TSSM) and instrument cluster on 2004-present models
• Support for new 6th gear indicator on 2007-present models
• Extended data logging and diagnostics, stores a full 60 minutes of operating data at 10 samples/second
• Supports all sensors including theft/security module
• All outputs protected against short circuits
• Billet aluminum housing with black anodized finish
• Easy plug-in installation

TCFI kits are available in a Race version and a CARB compliant 50 state street legal version
This TCFI kit is the Race version

Kit includes TCFI III plug-in fuel injection controller, USB interface for PC link, Windows XP/Vista/7 software on CDROM, WEGO IIID dual channel wide-band exhaust gas oxygen sensor interface, two Bosch LSU 4.2 wide-band oxygen sensors, and two 18 x 1.5 mm weld nuts for exhaust pipes
