What do you guys do to adjust the speed and fuel useage?
As mine is about 7% wrong due to the 315 tires?
ForScan (adjust tire diameter in MM)

There is also a calculator (probably accessed in the ForScan page) as part of the F-150 spreadsheet that will use GPS speed versus speedometer speed to give a value to put into ForScan.

I found a value at 50mph, 60 mph, 65 mph, 70 mph, and 80 mph. For me, I was happy with the results at the 70mph test.

The straight mm adjustment gave me horrible results. I was close to 8 mph off at 70... on the high side.

thanks, so in short,

I purchase a usb cable like this: https://www.amazon.com/dp/B094Z7PBLS
and download forscan and adjust the values that reflect my current setup?

This also fixes the mpg differences and my distance counter? (although I kinda like my total miles drived overall doesn't reflect the actual number (as it is off by 7%) ;)

Yes.

Also, the software only works on Windows computers.

I would go over to the ForScan sub-forum and read up on things there. Keep in mind the the 2020+ models are finicky with ForScan. I just read a few posts about it and it looks like the Over the Air (OTA) updates can overwrite ForScan settings in the newer models.

I don't know what all settings this may impact. LokiWolf really has his finger on the pulse when it comes to ForScan.

Not mine, for sale at my local dealership for you guys or gals looking at the 2022's
285's
Any idea on the full scope of work to get that? Is it stock with bigger tires? A readyLIFT and bigger tires? A full coil over upgrade and bigger tires?

Inquiring minds want to know!

It had the Ready Lift 3/2. When I first spied it I thought it was a timberline. It was just a plan Jane XLT. Didn't look like any trimming, they also added the side steps. This is how the Timberline should have came. They don't even look lifted on the lot.

Trying to decide between 295/70/18 and 35/12.5/18 on my Timberline. Front end is definitely lifted compared to other 22's I compared on the dealer lot. I've been really busy but going to mount my 35/12.50/17's from my Raptor as a test fit. Definitely need more tire width for FL sand. Looking at suspension options.

Rough Country 3inch Kit
295/70/r18 (34.5”) Cooper Discoverer AT3 XLT

16.5 inches of clearance at running boards behind front tires. 17.5 inches of clearance at running boards I front of rear wheels.

No rub whatsoever with this setup!

Looks great! - thanks for making me decide on keeping 18's rather than moving to 20's on my Timberline. (have 35 x17's on my Raptor and Rubicon and love meaty tires) Is that a 18x9 0 offset wheel?
