Product Details

AEM’s Serial Gauge plugs into the AEM's Programmable EMS and has the ability to read 19 channels simultaneously to provide reference for all outputs, such as 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 "daisy chain" multiple Serial Gauges together to monitor additional channels or to divide your readouts across a few gauges.

NOTE: The Serial Gauge only works with version 1.19 and newer EMS firmware.
