OK what I found and could see was if I was a tiny bit slow on the center button, (like held it a split second too long…)when the screen changed it would/could also change the value of the number in the next screen.

This happened to me a couple of times so now having the known and correct default settings I could make sure each screen was set to the default.

So for 2000 Ford Crown Vics and Grand Marquis VSS is 15900 and a good starting point and near match to my scan gauge GPH idling is 013500000.

I will of course do a tank or two of gas and farther calibrate.
