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.
The range of adjustment is +/- 2.5 V on the MAF sensor signal. The absolute maximum allowable increase in injector size is 100%. We don't recommend going that large; we recommend a maximum of no more than 50% increase over stock cc volume. The R4 software is included with this unit.
NOTE: This Unit DOES NOT Come Pre-Programmed And WILL NOT Work With 6 Cylinder Applications.
