17401 Tcfi 4 Efi Controller Sportster

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 can’t cope.
