    Has anyone figured out how to configure a Custom PID within the iOS app ODB Fusion for reporting the automatic transmission temps in the 01-04 Tacoma's?

    Let's not get sidetracked by "what you can do this?" "Get a scangauge" "get an Ultragauge"... because I have a ScanGauge.

    Screenshot of the app and the configuration options:

    I’d like to know if anyone has figured this out as well.

    Bump ... I'm struggling to get anywhere, but found this vague documentation for ODB Fusion about User Defined PIDs:
    https://obdsoftware.force.com/s/article/user-defined-pids

    Combining with cross referencing the ScanGauge II and Ultra-Gauge MX settings, I may be able to figure this out...

    Scan Gauge II
    Gauge Auto Trans Temp
    TXD 686AF101B4
    RXF 044105B40000
    RXD 2808
    MTH 00090005FFD8


    Ultra-Gauge MX
    TData 686AF101B40000
    TCtl 85
    RCtl 00
    RPos 2808
    Mtch 41B400
    X 0009
    / (Y) 0005
    + (Z) FFD8
    Out Format 00
    Ave 00

    I worked at this for a long time and ultimately determined that not all trucks ECUs report the trans temp.
    The correct PID is 01B4. I tried every thinkable combo on my truck and never got it to work. You can try putting "01" in the OBD module and "B4" in the PID spot.

    Edit, I also used Engine Link with the same results. You can reference this thread about 4runners, but they are very similar. It might have something to do with California emissions ECUs vs the standard. My truck is standard.
