June 2020 Ford Ranger software error, and the ECU; resetting ODO/Speedo caused significant errors

[RedlandRanger]

Schools don’t teach the lower level stuff that you need to know for things like ECUs, they focus on the WYSIWYG stuff that looks pretty.

Don't get me started on how many times I've argued that it doesn't matter what it LOOKS like if it doesn't WORK. The obsession with "pretty" drives me nuts.
