Upgraded Fuel / Timing Calibrator

(4 Cylinder)

For 4 Cylinder Tacomas and 4Runners using larger than stock fuel injectors. This unit calibrates the 0-5 V MAF sensor signal and intercepts the variable reluctance cam and crank sensor signals. This unit has an internal enrichment module that works with either narrowband O2 sensor or wideband air/fuel sensors. The module allows a richer fuel mixture in boost at part throttle. This can run up to a 50% larger injector. If you have a 2RZ/3RZ a 440cc injector would be ideal.

The range of adjustment is +/- 2.5v on the maf sensor signal. Absolute maximum allowable increase in injector size is 100%. We don't recommend going that large and no more than 50% over stock cc volume. R4 software included with this unit.

NOTE: This unit does not come pre-programmed and will not work with 6 cylinder applications. Not street legal in California.
