MAP-ECU AFR Sensor Adjust Module


This add-on module for the MAP-ECU2 will allow you to modify the signal from the vehicle’s Air/Fuel Ratio Sensors so you can alter the fuel mixture when the ECU is in closed-loop mode.

Starting in 1999 Toyota started using a new type of O2 sensors on some vehicles and this is Toyota/Denso’s version of a wideband O2 sensor.  By 2001 these new types of sensors were being used on all of the Toyota trucks.  If you have a vehicle with this new type of O2 sensor this add-on module for the MAP-ECU2 will allow you to manipulate the fuel mixture in the closed-loop mode of the ECU.

This is an add on module and will only work with a MAP-ECU2 and is controlled by using the AFR Adjust table in the tuning software.  If you do not have a MAP-ECU2 and wish to manipulate the fuel mixture while the ECU is in the closed-loop mode you should consider the URD AFR Sensor Calibrator.
