The best feature of the AEM X-Series Wideband Gauge? It’s the display and the striking modern faceplate. The seven segment centre display makes it easy to read on the go, while X-Digital technology allows the device to measure a wide array of outputs that other sensors can’t. For ease of use, its display is actually 87% larger than other options on the market, allowing drivers and navigators to glean an accurate reading as quickly as possible. The gauge includes a 0-5V output port, for accurate data logging whatever device or engine management system is used. Thanks to its impressive response time, the gauge offers drivers a safe, powerful, and accurate tune. Users reported that the device warmed up much faster than many options on the market.

Keep in mind that if you do happen to have any issues with the sensor on the device, you won’t be able to get it replaced since it isn’t covered under the manufacturer’s warranty.

The impressive Innovate Motorsports Wideband Gauge is a fantastic product for those who want to get info ASAP. It’s speedy and efficient, and the gauge not only displays the engine’s air/fuel ratio, but it can also provide feedback on the vehicle’s O2 sensors.
