The AEM X-Series wideband gauge, while powerful, may lack a dedicated data logging output wire beyond the standard OBD2 port. However, it utilizes a sensor for accurate readings. To effectively log data, a separate interface like the Tactrix Openport connector is typically required. A common setup involves using a wideband controller with a dedicated data output, such as the Uego, connected to a serial-to-USB converter. This allows software like EvoScan to read and log the wideband AFR values through a designated COM port.
Alternatively, if your vehicle supports it, the unused wires from a disabled secondary O2 sensor (often requiring a specific ECU mode like Mode 23) can potentially be utilized for wideband data logging. However, this method requires more in-depth knowledge and configuration.
The AEM X-Series likely offers a method to export live data, potentially for integration with an AEM Infinity ECU. Identifying the specific output signal type is crucial. If it’s a serial output, similar to other AEM wideband systems, the serial-to-USB method described earlier might be applicable. This involves connecting the signal and ground wires from the wideband controller to the corresponding pins on the serial-to-USB converter and configuring the software to recognize the data stream.
Successfully implementing this method requires pinpointing the correct signal and ground wires on both the wideband controller and the serial-to-USB adapter. Once properly connected and configured within your data logging software, real-time wideband AFR values should be available for logging alongside other engine parameters. Understanding the specific output of your AEM X-Series gauge is key to determining the most effective integration method with an Aem Infinity Obd2 setup. Consult the AEM documentation for detailed wiring diagrams and signal specifications to ensure compatibility and accurate data logging.
