AEM Electronics X-Series OBDII Wideband AFR Controller Gauge (30-0334)

Adding an AFR gauge to the mix is the best way to monitor exactly what air to fuel ratio the engine has to work with at any given moment. This single piece of information is perhaps more definitive of performance than anything else. That doesn't mean you need to go overboard to get the data, though. This AEM X-Series OBDII Wideband AFR Controller Gauge makes use of what the vehicle already has to work with, meaning you don't need to do away with factory-installed sensors. The X-Series Wideband AFR OBDII Gauge includes an OBDII pass-through, which provides accurate AFR readings right through the factory ECU CAN-bus – ideal for tuners who are using piggyback tuning modules or open source software.

Thanks to AEM Electronics’ patented X-Digital wideband technology, X-Series Widebands are the fastest responding wideband air/fuel ratio controllers in independent testing against 17 other wideband UEGO air/fuel controllers. High-speed readings ensure no loss of signal fidelity and full transient response, making the controller able to identify the slightest fluctuations in AFR and output them in full value.
