AEM 30-0300 X-Series Wideband UEGO AFR Sensor Controller Gauge

#ad
AEM #ad - X-digital wideband technology gives these controllers the ability to read and report values that other controllers do not, which can deliver more optimized engine tuning and a safer overall operating condition.

Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune. The gauge includes a 0-5v and rs232 serial port output for feedback control and data logging, and an AEMnet CANbus output for data logging. When tuning an engine using wide-band afr feedback control on an inertia dyno, dead time affects the data you are looking at because it is reported in a different operating location than when it actually occurred. The x-series wideband uego afr sensor controller gauge pn 30-0300 features a modern, visually striking faceplate and new seven-segment center display that is 87% larger than the 30-4110 AEM.
