Wide band sensor
Smile
I have a 2004 h-2 hummer with two wide band heated oxygen sensors, 4-wire, wide band type. Does the double EFIE have 4-wires for each sensor? Is that the unit for me?

RE: Wide band sensor
It has two wires for each sensor.

2 wires for heater.
2 wires (1 sense, 1 ground) for sensor.
4 wires total.

BUT the EFIE currently works only for narrow-band sensors.

I recommend that you read http://www.fuelsaver-mpg.com/doc/TuningForMileage.html . You'll find some alternative handlings that you can do. I recommend the MAF, IAT and CTS handlings, as well as the resistor for your wide bands that are described.
