AEM gauges allow quick and accurate assessment of a vehicle's operating condition. These precise gauges make certain any problem is detected at the earliest stages and can prevent serious damage and costly repairs. Gauges are offered to monitor air/fuel ratio, boost levels, fuel pressure, oil pressure, oil temperature, transmission temperature, voltage, water temperature, as well as datastream readouts from AEM's engine management units. Digital gauges feature 24 color-coded (Red, Green, Yellow) LED lights that change from green to yellow to red for immediate reference to the measured parameter, and an integrated thee-digit display that reveals real-time operating conditions. The LED display provides precise reference to critical operating conditions and alert driver of potentially damaging operating conditions. Analog gauges feature a backlighting that is user adjustable to 7 colors, (white, blue, green, red, orange, light blue, and aqua), allowing users to easily match the wideband gauge to most factory gauge clusters. The needle provides accurate real-time readings of the vehicle's operating conditions. AEM's Serial Datastream Gauges offers user customizable and has the ability to read 19 channels simultaneously to provide reference for all outputs, including boost, AFR, EGT, H2O, IAT, knock, volts, RPM, vehicle speed, and more. Since it can read all channels at once, AEM’s Serial Gauge eliminates the need to buy a cluster of gauges, or you can link multiple Serial Gauges together to monitor additional channels or to divide your readouts across a few gauges.
