Thread: Aux Temp Inputs

    Aux Temp Inputs

    Are there any provisions for an additional temperature sensor on the EFIS or EM modules? I would like to add one or two temp probes and have them alarm at setpoints I define. Since I am planning an injected installation, the carb temp sensor comes to mind as a possibile unused input. Alternately, since I have only 4 cylinders, I presume that there are 4 unused inputs (CHT/EGT for cylinders 5 & 6) built into the hardware & software?

    You could use the Carb sensor, the spare EGT and CHT will only display on the CHT and EGT graph.

    Thanks Rob, is the carb temp input expecting a type J or type K thermocouple?

    It is a special Thermistor, you will need to purchase it from us.

    OK, what is the max temp for this thermistor? Need to understand if it is high enough to function as a fire sensor or whether I need to use a thermocouple on one of the unused EGT inputs. While I'm at it, is there a 4 cylinder version of the 4500 and a 6 cylinder - or is there only one version and they are identical, such that the unused EGT/CHT ports will be available to me in my 4-cyl installation?

    Thanks.
    Highest Regards,
