Dual Wide Band EFIE - Basic

Closeout Special!

This is our original wide band EFIE. It will handle 2 wide band sensors. Because we want people to treat all of their sensors, both upstream and downstream, this product has been replaced with our Quad Wideband EFIE. However, this device has the same circuitry for handling 2 wide band sensors, at a reduced price.

This product will work with all wide band oxygen sensors and AFR sensors, both 4-wire and 5-wire types. Also note there is a variation of the 5-wire sensor that uses 6 wires. This EFIE will work with these too. Please note, it will NOT work with narrow band sensors.

This model comes in a mountable box, and encased in protective plastic. The included wiring is 18 gauge, with quick disconnects that can unplug from the device for easy installation. It has one potentiometer that controls the air fuel ratio adjustment for both sensors. An LED shows when the unit is powered up.
