A Gauge for You and Logging for Your Tuner
If you’re filling out that gauge pod, a wideband would be a great choice because it’s an excellent way for you to quickly check how well the engine is running while on the road. The trouble is that a visual display isn’t helpful for your tuner. They’ll need to see Air/Fuel Ratio (AFR) information in context with the rest of the critical engine data to get and keep your car running at peak performance. Our iWire Spec modifications to the wideband kit factor in simultaneous logging and display with a simple plug and play install.
Stop Hunting the Web for How to Wire Your Wideband
We’ve all been at the point where your eyes are red, and your brain is mush after reading a bunch of posts about different ways people have wired up their AEM wideband gauge. The cars are always different, and the wires don’t match up. Instead of wasting your time with all the hunting around on the web and still being unsure, just run a couple of wires from the engine bay into the cabin, and plug them in. You’ll be “widebanding” in no time!
I Have a Factory Front Oxygen (02) Sensor. Isn't This Enough for Tuning?
Unfortunately, no. The front O2 sensor (the one in the header) is sometimes considered a wideband sensor. Still, it technically doesn't have a wide enough range for proper tuning. It will stay in the car for ECU to function properly, but the factory sensor's lack of accurate Air/Fuel metering leaves a need for an additional upgraded wideband sensor so that your tuner can safely calibrate the car whether in person or remotely.
2002-2005 WRX: Wideband works with this car for data logging the raw value (will need to be converted from voltage to AFR outside of the AP) and gauge display on the AP will be the raw value of 0-5 volt as well.
2004-2013 Forester XT
2005-2012 Legacy GT
2005-2009 Outback XT
This product is no longer compatible with the Cobb AP. It can still be used for datalogging with alternative tuning methods.

Unfortunately iWire cannot sell the plug and play wiring separately from the unit because the wiring harness of the unit must be modified in house.
