With 35x12.5 shows 6 mph lower than GPS.

Mine did, too, until I changed the tire size using the MM3.

You changed your tuner to show 35s, and it’s still off by 6mph?

So I’ve messed around with it and can’t figure out how to make a custom screen.

I want EGT, engine temp, tranny temp, boost, and maybe rail pressure on one screen.

How do I do that?

I find it odd that a $1,500 tuner doesn’t come with instructions, nor are there any on the internet.

Wheel size doesn’t matter when calculating MPH.

Only over all tire diameter.

I agree the lack of a comprehensive MM3 user guide is very disappointing.

Most of us have to figure it out by trial and error.

The attached Smarty Touch user guide is a handy reference for getting started.

So I am far a way from any MM3.
