Thread: Transmission Temperature ECU Input

  1. #21

    Hi Danny. Changed to custom thermistor as you've stated. I did configure the gauge section as I believe to be correct, entering sensor minimum -20° sensor Max 130° with display Min & Max the same. Set the caution and normal values as required. Software version V2.2.0 build3. Still doing the same.

    I don't understand what's wrong. I just did it, and it works fine:

    Hi Danny, I see the difference now. I had the lower temperature values commence from left to right, thinking that it wouldn't matter, provided the correct resistance value corresponds with temperature. Cheers.

    That's been a stumbling block for many users. In post #1, I included a "Recap" paragraph to help emphasize it.

    Recap:
    Correct data entry for the Auto Meter #2259 Input:
    1) Create the "Thermistor" Input; name & enable it.
    2) Configure as "Custom Therm", Units "°F" & Format "1".
    3) Adjust the displayed gauge Min & Max values 100°F-340°F.
    4) At top of Calibration Table, enter temperature scale 340°F-100°F (from left to right).
    5) At bottom of Calibration Table, enter Sensor Resistance-Ohms 20Ω-1123Ω (from left to right).
    6) Then "Pin Map" the new Input to an available ECU connector input pin.
    That's it. The sensor is inexpensive, compact and self grounding, so it's an easy one wire connection.
    May God's grace bless you in the Lord Jesus Christ.

    Danny, thanks for that; very easy to setup.
    Without being in front of my car; I believe it's possible to display the value on the new screen, right?
    Regards, Dylan

    Yes, just add that gauge/meter from the I/O channel list (like you would normally).

    Danny, you could by all means (if anyone had room to) just use the Holley SS sensor, to read transmission temperature, correct?

    No! The Holley transducers (Link) are pressure sensors, not temperature sensors.

    You can use the Coolant Temperature Sensor to read transmission temperature (or oil temp, or any fluid temp)...that's what I do.

    Danny, I tried for the very first time to read the transmission temperature but it stayed at 100°.
    The wiring is OK, values as per your topic (I have a 1-wire transmission temperature sensor from Auto Meter).

    While the engine was cranking, it was displaying 300+ so it seems to have read something, and then once engine running, always the same 100° value.

    I'm also having the same issue with the VSS sensor, I also followed your topic, but it does not give me any value.

    In the input tab, both are "Enabled", so I suspect there is nothing else to check somewhere else? I put both inputs on the first inputs J1-A12 for the speedometer, and J1-A3 for the transmission temperature sensor.

    The only thing I'm unsure is before starting the car, laptop was connected and on display gauges. I also added those, so I suspect having the values on the laptop and the new screen, is compatible?
