I am sure it's pretty simple, I remember fooling around in the custom settings prompt where it asks you whether or not you want to designate any custom settings before loading the tune. Is the tire size in there and does it allow you to designate tire size in actual dimensions.

 

No Josiah, it asks you for rev's per mile for the new tire size. I went to BFG A/T 285-65-18 on my screw. I went to BFG'S website and found the info. My stock BFG'S were 664 rev's per mile and the new ones were 634 so you have to round to the nearest 5 revs.

 

I assume that is something that can be changed and not screw up the Troyer tune? Say, if I went from the stock 255/70/17s to say, 285/70/17?

 

Yes you can change tire size and not affect anything else in the tune. I questioned Crystal at Troyer's at length about this. Once you input a new tire rev's per mile it saves it in the x-cal and uses that new size for all the stored tunes. If you ever go back to stock tire size and stock tune you will have to re-input the stock tire revs per mile though.

 

Very well said!

 

Thank you sir! Now if I could just figure out this dang data-logging stuff. :o
