    So trying to program this Ultragauge MX 1.3 for the torque converter lockup display and find that codes provided on another tread here appear to work as I don’t get the ERR anymore but the display now shows 0.0 and 1.0 .Start it up and it displays 1.0 then goes to 0.0 when you move it. Driving around and it alters between the 0.0 and 1.0, have gone through the code numerous times and can’t find anything wrong with it. I forgot to write down the original code when I modified it so I can’t go back and look at that code.
    I sent a support request to Ultragauge and they were no help at all, sending me to look at their manuals that show nothing but trans temps.
    Since these things come preprogrammed with the codes for the 2005 to 2011 Tacoma’s can somebody post a pic of one from these years that show the codes installed.
    Also anybody with 2012 - 2015 that has codes that work.

    The lockup value is worthless. It is only a 1 when in an odd number gear (1,3, or 5) and 0 when in 2 or 4. Does not indicate lockup of TC.

    Nice to know, have spent hours trying to get the gauge to just read a 0 or a 1 and not the 0.0 and 1.0 that it shows now.

    Bumping this thread up.

    I've got a 2015 and a brand new UltraGauge MX 1.4 as of tonight. The pre-programmed Torque Converter lockup MGauge just displays Err for me as well.

    I can read the lockup value with a cheap WiFI ELM device and the iOS "OBD Fusion" app, so I know the ECU supports it.
