Daytona Twin Tec TCFI Gen 4 Auto-Tune Fuel Injection Controller 17400

Fully programmable plug-in replacement for the 36 pin Delphi controller with J1850 data bus. Simultaneously auto-tune fuel curves for front and rear cylinders under actual riding conditions with WEGO IIID dual channel wide-band oxygen sensor interface. Robust alpha-N (throttle position and RPM based) fuel control eliminates problems with long duration/high overlap camshafts. DataFLASH memory stores full 60 minutes of operating data at 10 samples/second. The TCFI kit includes the WEGO IIID dual channel wide-band exhaust gas oxygen interface that allows auto-tuning during dyno tuning or actual on-track 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. The TCFI also has built-in data logging that stores data for the last 60 minutes of operation at 10 samples/second. PC communications is by means of a USB interface that plugs directly into the existing H-D diagnostic connector. Windows compatible software allows use of laptop for programming and data analysis.
