The spreadsheet has two items related to speedometer calibration (rows 15 and 91). Both indicate a Check Engine Light (CEL) when setting for 37" tires. Is this a one time light that can be easily cleared or will the light stay until you put the setting back to something else? I have 37's and would like to set the speedo accordingly but not if I will continually get a CEL. Appreciate any input
so with the CEL coming on when people change the speedo ... Has anyone tried getting the ABS re-calibrated after changing the tire size using FORSCAN? I ask this because on one of my earlier trucks you needed to change the parameters in the ABS module also in order to not get a CEL. If this has been tried just disregard
I believe this is what livinitup indicated to me had been tried previously, i would like to figure out how.

The 285/75r18 code does not give a cel, thats about as big as you can go without one
the code for 37's is dead on with my 37x12.50r20 toyo r/ts. It sets the engine light in the lower left of the dash, it doesn't do a warning message, chime or flash, just stays steady on kind of like the exhaust brake light. I thought it would bother me but it doesn't. and checking codes with my ez lynk nothing comes up in pcm so i assume youve got to have a real scanner to read it in the abs module or whatever. Worth it to me until someone figures out how to make the change across all the cm's
There's this value in HSWM but guys that have tested it on the F150 didn't see that it made a difference but you could try it:
714-01-01 1xxx xxxx xx Timeout disabled
Thanks, I will give it a shot, but I think I remember looking for HSWM before and couldn't find it.

Will do! Hopefully I get time this weekend. Anybody want to borrow a few kids for a few weeks. Between running them everywhere and taking care of this new puppy, I've got no time for myself!

I'll have to do the math to see how much closer the speedo gets if set to the max 285/75/18 vs stock setting and then how that compares to my 37/13.5/22. Sounds like it would at least improve. I hate having dash lights on if I can avoid it.

Hmm, looks like Super Duty is different than F150 and if the truck has active steering then there's no HSWM but it uses SECM instead. I'll see if I can find something for values in SECM
Edit: just checked my other software program and I don't see any vehicle in there with an SECM module so I can't help with any values.

Again, thanks for your help! I'll try to get some time to do some digging this weekend and see what I can find...

mine was off about 3.75 mph at 70 with the 285-75 code and 37's 5.5%
I've pushed my regens out to around 1200 miles between full regens up in Alaska this winter. The colder temperatures don't seem to build as much soot, so I monitor the PID's and when I get close to the mandatory 500 mile regen, I watch the EGT PID's like a hawk. As soon as two of them go over 1000 degrees, I pull over and shut the truck down. I turn it back on, and it shows 0 miles since last regen and it's no longer in regen mode. I continue down the road and my 35-40% soot level slowly increases until the next time a 500 mile mandatory regen wants to start, then lather rinse and repeat. When it gets to a real regen (100%) soot, I make sure to let it run it's course to 0%. Works like a charm.
worked with forscan a bit today with my 2017 f 250
enabled heat seat icons only on radio
enabled dpf mode gauge
enabled bambi mode and it worked fine ,but it turned the dpf gauge off strange!
turned bambi off had to tuern dpf on again this time it stayed populated on
,anyone have any insight on this one !
ran out time to tinker lil more, will this weekend if its nice out
