What AEM controllers is this sensor compatible with?

This replacement sensor is compatible with AEM Infinity Engine Management Systems and specific controller part numbers including 30-4100, 30-4900, 30-2310, 30-2340, 30-5130, 30-5143, and 30-2320.

Does this sensor require calibration?

The Bosch LSU 4.2 sensor is factory-calibrated to within 0.1 AFR. It does not require free-air calibration when used with a compatible AEM wideband controller.

What is the purpose of the calibrated resistor?

The sensor includes a laser-etched, calibrated resistor in its connector body. This resistor is specifically matched to the sensor it is attached to and ensures accurate output. Modifying this resistor will invalidate the sensor's performance.

Product Details

AEM's Bosch 4.2LSU Wideband UEGO O2 replacement sensor kit includes only the sensor (with attached cable and male connector) and is intended to replace an existing mounted wideband sensor used with AEM wideband air/fuel UEGO controllers.These sensors have a laser-etched, calibrated resistor in the sensor's connector body. This resistor is specifically created for the exact sensor that it is attached to. Modifying this will invalidate the sensor's output. The wideband sensor is laboratory-calibrated at the Bosch factory, accurate to 0.1 AFR and never requires free-air calibration when used with an AEM wideband AFR controller.Replacement Sensor for the following AEM Wideband Controllers.AEM Infinity Engine Management Systems30-4100 - Digital Wideband UEGO Gauge30-4900 - Wideband Failsafe Gauge30-2310 - Inline Wideband UEGO Controller30-2340 - 4-Channel Wideband UEGO Controller30-2340-N - 4-Channel Wideband UEGO Controller - Nascar30-5130 - Analog Wideband UEGO Gauge30-5143 - Analog E85 Wideband UEGO Gauge30-2320 - X-WiFi Wideband/EGT ControllerBosch LSU 4.2 Wideband UEGO Replacement Sensor
