The TFi does not alter the factory air/fuel computer tables or pulse-width calculations. The unit simply taps into the injector driver circuitry leading from the ECU to the engine and selectively appends extra pulse-width voltage to keep the injectors open the exact incremental time required for precise fuel enrichment. The vehicles on-board computer and wiring harness remain intact and no wires need to be cut. The stock air/fuel map remains intact as does the correlation to the engines volumetric efficiency curve.

The TFi is simple to adjust with four settings on board the control unit. These dials respectively define the breakpoint between cruise and main-jet RPM. Turning the dials simulates. changing the adjustment of idle jetting, cruise jetting, and full throttle main-jetting and accelerator pump jetting on a carburetor. LED lights provide status information to the tuner. The transition from mid-range to main jet operating ranges is user selectable via dial and LED. The TFi has a simple self diagnosing installation and returning to stock fuel is achieved by minimizing the setting.
