2022 f550 speedo fix

[awitt94]

Hello all,

Ive been using hp tuners for a little over a year now, and have recently ran into an issue with the new ford powerstrokes. There is no longer the gear/tire wizard tab in the drop box which is what I have been using in the past to make tire change adjustments. I tried going under the "speedometer" tab and manually adjusting the tire size there, but after making my changes the speedometer is still off by about 10-11mph. I changed "use tire circ." from "learn from BCM" to "Calibration", then tried adjusting the min/max values but still with no luck. Any help is appreciated!!

im currently having issues as well. primarily i have edited gm vehicles with gear tire wizard and now ive been having requests for ford vehicles. i tried a 2019 ford f350 6.7L im not sure if i didn't purchase the right amount of credits. i got 4 to enable the tcm for tuning when in and adjusted the tire revs per mile under the speedo tab. went to write the vehicle and just takes me back to the speedo screen. i assumed i would only need a license for the tcm only but if i buy the credits for the ecm as well im concerned it still will not allow me to make the changes or it simply wont work . anyone tried ? i hate to buy credits for nothing but i have several customers wanting to calibrate for larger tires. any help would be awesome
