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.
