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.
• Continuously auto-tunes fuel curves for front and rear cylin-
ders under actual riding conditions with WEGO IIID dual chan-
nel wide-band oxygen sensor interface.
• Robust alpha-N (throttle position and RPM based fuel control 
eliminates problems with long duration/high overlap camshafts.
• Extended data logging and diagnostics. DataFLASH memory 
stores full 60 minutes of operating data at 10 samples/second.
• Powerful Windows software for custom programming and 
extending data logging and diagnostics.
• The TCFI solves tuning problems with highly modified 
engines. High-end automotive racing application use ALPHA-N 
(throttle position and RPM based) fuel control. ALPHA-N elimi-
nates any dependence on manifold pressure and if unaffected 
by long duration/high overlap camshafts. The TCFI bring this 
prove technology to the market places. 
• Idle air control including idle RPM and cold start characteris-
tics are fully programmable. This facilitates the use of aftermar-
ket throttle bodies with higher air flow.
• Includes TCFI Gen 5 fuel injection controller, USB inter-
face for PC link, 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 1.5mm weld nuts 
for the exhaust pipe. 
Fits 2012-up FXST, FLST, 2012-17 FXD.
