AEM Wideband X Line Series with iWire PnP - Installation Guide
This guide is for the following Part Number.
PP-SUWB001-0
This part is a modified version of the AEM part number 30-0310. The link below is for the AEM instruction notes.
The replacement sensor part number is 30-2004
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.
It is not possible to add a gauge to this kit due to how the product is designed. If you need a physical gauge, please check out the AEM Wideband X-Line Series with Gauge with iWire PnP

DTM 3 Connector for CANbus and Serial Logging
This is an expansion port for CAN bus communication or Serial logging to a laptop. You can leave this connector capped, and tucked away.
ECU Map Calibration Notes
The ECU must be calibrated for any ECU logging to understand the new input. The problem is that the voltage range of the OEM Subaru Rear 02 sensor maxes out much lower than the wideband (around 1.25v max). Since the ECU was programmed with that 1.25v maximum in mind, it won't output anything higher than that number to your data-logging device. Once an adjustment has been made to the ECU calibration to allow for the full 0-5 v range, the wideband can log properly.
