OEM Engine Coolant Temperature Gauge (ECT) Functionality
Please note that the 30-6052 EMS is configured to drive the factory Honda ECT gauge by
outputting the appropriate signal on pin A1. This signal is calibrated to use the OEM
Honda engine coolant sensor; replacing the OEM sensor with one from a different vehicle
may change the behavior of the gauge.







Wiring accessories to the EMS:
Please follow this suggested wiring diagram when adding accessories such as UEGO
gauges, Boost Control solenoids, or switches for use with the EMS. Note that wire polarity
is not important for the Boost Control Solenoid.
