Ford Performance Tune for Gen 3s

[JBTAC]

Just finished flashing the fp tune. I did a loop through the neighborhood to make sure that the truck still drives and its all good, but I wont have an actual "review" for a few days.

One thing that I noticed on the handheld device is that you CAN adjust tire size. I was fairly certain that the website stated you cannot, and then it was repeated in this thread, but maybe I am misremembering. I've attached a few pictures of the menu to get to the tire size. I chose 560 revolutions based on my google search, but if anyone knows the correct amount for the factory 37" BFG K02's, please let me know! I never did use forscan to adjust my tire size last year when I went to 37's.

Yes it does allow for 560; it was reading in the 600's from the factory (35" spec truck) and I reprogrammed it to 560 based on my google results. I will try 569 next time I go downstairs, thank you!!

For programming, you click the number and it will give you a keypad to punch in the correct values. Then you hit continue and it'll make you do a "ignition on, car off......wait 10 seconds.....wait 30 seconds.....ignition off, wait 3 seconds, ignition on car off wait 30 seconds",.....etc. and then it programs.

There are also options for trans relearn, etc.

Why wouldn’t you just change it in forscan? The trucks are factory set for either 35 or 37 and it’s a very simple change and trans relearn.

I've never used forscan, but I did just download it and just got the OBDII cable to use it. I'm looking forward to removing the double honk when I get out of the car with the keys lol
