Air Boxes Closed or Open?!?!

What puzzles me is why the onboard gauge should be wrong. In theory the car knows the distance driven from tyre rotations, time is time, doesn't change, and from what I've see OBD2 speed readings are spot on.
Does anyone know where the error comes from?

Ford quality math?...

Time = Time
1 tire rotation = X Feet / inches
X Tire Rotations = X distance driven

If you drive your car 5 mph for a 1/4 mile then your mustang’s track app should be accurate. If you run a hot 1/4 mile (drag race) then you will have tire slippage. The question is, how much tire slippage.

X tire rotations in slippage = X feet / inches

So (X Tire Rotations + X rotations in slippage) =x feet which is less than 1320 ft. The track app will show that you finished in a shorter time. Hope this helps.

This all assumes that you have stock tires and that all stock tires are calibrated exactly which I don’t know if they are or aren’t.

Why give factual numbers when that will just make owners sad.

If they give favourable numbers then owners feel better about their purchase.

It's similar psychology behind why fitness watches report vastly inflated calorie burned numbers.

Thank you. Completely forgot wheelspin.

Does dragy use a satellite that ford is unable to ping?

No gyro or anything?

Draggy uses a specific amount of satellites that a phone doesn’t use. Not sure off hand without researching it in the interwebs but I think a phone uses something like 6 satellites and draggy uses 12.

I had to go look it up. Here are the GPS systems the draft communicates with.

Concurrent reception of up to four GNSS systems (GPS, Glonass, Galileo and BeiDou).

I don't know much about Dragy and V Box, but I did read that both refresh at a very high rate to keep acceleration data accurate.

That make sense. I definitely had tire slippage!
