AEMâ€™s X-WiFi Wideband UEGO Controller & EGT Monitor combines a single channel of our proven wideband UEGO technology with an exhaust gas monitoring function that supports up to two EGT sensors (sold separately).
X-WiFi installs easily and is small enough to conceal. It connects effortlessly to an iPhone or iPod Touch, allowing you to use your wireless device as an ancillary real-time AFR and EGT gauge. It is a must have for tuners and enthusiasts who do not want to add an additional set of gauges but want to monitor AFR and EGTs. A datastream output is also included for PC viewing of AFR and EGTs via a USB connection.
WHAT IS A WIDEBAND UEGO AIR/FUEL CONTROLLER?
AEM's Wideband UEGO (Universal Exhaust Gas Oxygen, pronounced â€œYou-Way-Goâ€) Controllers are powerful, cost effective tuning tools that allow users to accurately monitor the Air/Fuel Ratio (AFR) of their engine.
WHY USE A WIDEBAND AIR/FUEL CONTROLLER?
Accurate AFR data is critical when tuning an engine. Running rich (very low air/fuel ratio, excessive fuel) can cause a loss in power, while running too lean (very high air/fuel ratio, not enough fuel) may result in serious engine damage. Using a wideband air/fuel controller during the tuning process allows you to monitor AFR and adjust tuning parameters to optimize them for maximum power and efficiency. AEM has a comprehensive line of highly accurate, reliable wideband air/fuel controllers that can help ensure your vehicle is optimally tuned.
WHAT IS FREE-AIR CALIBRATION?
Some of our competitors require that you frequently perform a free-air calibration procedure to calibrate their O2 sensors. This process involves removing the sensor from the bung while still connected to the controller device, then waving the sensor in the air so it can read atmospheric O2 levels. We use Bosch 4.2LSU sensors in our wideband controllers. Our sensors are individually laboratory-calibrated by Bosch and never require free air calibration!
CAN I CHANGE THE AEM UEGO SENSORâ€™S CONNECTOR?
No. There is a laser-etched, calibrated resistor in the sensorâ€™s connector body. This resistor is specifically created for the exact sensor that it is attached to. Modifying this will invalidate the sensorâ€™s output.
