Daytona Twin Tec TCFI 4 EFI Controller Delphi [MPN: 17400]

Product Description

The TCFI kit includes the WEGO IIID dual channel wide-band exhaust gas oxygen interface that allows quick auto-tuning on a dyno or on-road during actual riding conditions. The kit includes Bosch LSU 4.2 wide-band sensors for both front and rear cylinders. The 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 cant cope.

• Fully programmable plug-in replacement for the 36 pin Delphicontroller 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
• Not compatible with 08-13 Touring models with electronic throttle control or 11-13 Softail; 12-13 Dyna models with CAN data bus
• Extended data logging and diagnostics
• Powerful Windows software for custom programming and extended data logging and diagnostics
• Idle air control including idle RPM and cold start characteristics are fully programmable
• This facilitates the use of aftermarket throttle bodies with higher airflow
• For 01-13 Twin Cam using 36 pin Delphisystem with J1850 data bus
