    Yes, uploaded my saved Global File, plus also created a new Global File. Same results each time.

    Ryan, you can test your sensor with a multimeter: https://www.1aauto.com/content/artic...sensor-testing, or replace as you stated before. But I find it strange it broke after the update. To rule out a physical issue I'd suggest testing the sensor.

    I'd find it highly odd as well that it quit working at the same time I did the update. But I'll test it just to rule it out.

    Yeah, stuff that stops working at the same time as an unrelated change is really challenging. Sometimes it's just bad luck. You have to put all the assumptions aside when chasing down a problem and just go back to basics. Test everything and don't assume that anything is good until you verify it.

    That's the plan hopefully get at it tonight or tomorrow and narrow it down some more.

    Is there anywhere to find V5 Build 30 software? I’ve located an ECU to try that's on V5 Build 30, and being it’s not mine I don’t want to have to do a firmware update to it. Just wanted to test and see if it shows a crank signal. Or is it possible to use V5 Build 140 software with the older firmware?

    So if I’m reading that correct, I'd need either V5 Build 30 or V5 Build 31 then?
