Don't know what else to call it, so, anyway it's the display between the tach and speedo. At one time, I seem to recall a way to get into some sort of engineers section to change settings, also seem to recall that one of the settings you could change were tire sizes, OEM sizes that is. Since I'm running 315/70/17, OEM for a Raptor, would I be able to reset speedo for that size?
Maybe all that was one of my more lucid dreams.

 

I don't believe the 'engineering setting' in the info system has the option of changing anything but the MPG settings. I don't believe Forscan will allow you to change tire sizes, I could be mistaken on this. A tuner is usually the answer to making these kind of changes. Mine will do tire sizes and gear ratios.

 

Forscan will make the changes

 

I could be entirely wrong, I do remember some guys getting the MPG readout to be more accurate.
Ya, I have an nGauge I took off my '17, just need to get it unmarried [divorced,LOL] from that one, then set it upfor my '20.

Man, I went and got the dangle and the license probably 2 years ago. I'm scared to death of getting into it, so have never used it.

 

It's called Engineering Test Mode

 

Nothing to be scared of using Forscan, I found out you can use it to change tire size from a thread that's currently going on. You might check it out.

 

Yes, that's it! As the guy scrolled thru it, I didn't see what I'm looking for. I'll get out there and take a slower look. Thanks!

 

My truck must be the only one with engineer mode disabled.

I've tried and tried (both methods I've read) and I get zilch.

 

Don't say that, I haven't tried yet.

 

Some work with holding the OK button while turning the key to on and some work with holding the OK while starting the engine. My 2017 has to be started
