AEM X-Series Inline Wideband AFR Controller Kit Specifications

This 100% digital AEM X-Series wideband AFR controller kit is the fastest on the market, according to independent test results. It features a compact, weatherproof enclosure and status LEDs. This space-saving solution is ideal for users who do not require an AFR gauge and want the fastest response time when datalogging or tuning with an engine management system.

This controller kit comes with a Bosch 4.9LSU sensor and requires no calibration when fitted. However, it can be recalibrated later as the sensor ages. This sensor is extremely fast, stable and has very low power consumption (low amperage). The controller includes a 0-5V output and an RS232 serial port for feedback control and datalogging, as well as an AEMnet (CAN bus) output. It supports voltages up to 16V and is compatible with fuel-injected or carburettor engines.
