This might be a silly question

I have a 6 speed manual, and I have 285 65R18 tyres, using the calculator tells me the 09D2 is the number I need to enter.

is 09D2 higher than 0984, the max value i can enter?

Cheers

Noob question warning: I am VERY new to FORScan. I've got a 2022 Ford Ranger Raptor X and I've tried to change the tyre size to compensate for the 35x12.5 I have.

I've inputted xxxx-0A8D-xxxx on line 726-12-01 and now I need to do a TCM re-learn but I'm not sure how or where to do that.

Would someone be able to post a screen shot of where I go to do it?

Cheers

Ben

I have a had a decent look around the forum, and just want to confirm, a couple of things before I buy.
For background I would consider myself reasonably IT savvy.

My daughter has a Ranger XLS and has put Raptor rims and Tyres on it. If anyone is wondering they fit** without mods to suspension IF you get a wheel alignment. She did add 2" level kit to the car at the same time.

**fit = they are very close to the steering knuckle. Tyre fitters said many cars come standard nearly as close. At full lock, they do just graze the steering knuckle. When I say full lock, I mean steering wheel hard against the stopper, if you go to full lock and then back off imperceptibly it doesn't touch, so I am thinking its actually the tyre squashing against it from the turn.

OK that's the background, now to my question.

The stock tyres are 265/65/17
The Raptor rims tyres are 285/70/17

The calculator gives me this for the Raptor rims/tyres
True Circumference mm: 2610
Ford Corrected Circumference mm: 2524
Required BCM value at 726-12-01 is xxxx-09DC-xxxx

6 speed automatic. Your max value is 0977 unless you have my custom TCM calibration installed. Anything over this value will cause a DTC.

The speedo reads about
4km under at 110kmhr
3km under at 90/100kmhr
2km under at 80kmhr

I don't want to make a change that throws and error, but would like to get the speedo largely correct.
I don't understand what "ford corrected" circumference is? VS max value.

If I input the "ford corrected" value, is this a value that will not error, but will get the speedo mostly correct?

Thanks in advance, sorry if I have not searched enough for the answer.

"If it is a PX2 with 6 speed automatic. "Your max value is 0977 unless you have my custom TCM calibration installed".

It's actually a PX3 but I have a feeling that's immaterial.

As a side note: 0977 is bang on for the 285s also cant thank you enough for this wonderful resource!

Cheers,
Dave

Am I best to get the dyno tune first then make the change 0977 for the larger wheels myself using Forscan?
