This product will work with all wide band oxygen sensors and AFR sensors. To be clear, it is the EFIE of choice for both 4-wire and 5-wire oxygen sensors. Also note there is a variation of the 5-wire sensor that uses 6 wires. This device will work with these too. This device will NOT work with narrow band sensors. Note that this product is only available in a dual configuration at this time. This means that this device will control 2 wide band oxygen sensors.

For vehicles with single wide band oxygen sensors, just don't hook up the other circuit.
