InTune question.....

[VinnieB109]

Can anybody tell me how to just calibrate speedo for tire size? The only way I see how to do it is to load a tune first then it gives me the option. I don't want to load any tunes, I just want to change my tire size so the speedometer is correct.

I even tried "modified stock tune" but the only adjustable parameters it gives me is trans. The "adjustable parameters" isn't highlighted.

I think its in the modified, you just have to scroll through the parameters to tire size, but yes, it acts like it's losing a tune. It will save your current tune first, then you can just change tire size and save that

 

It will flash your ecm 3 or 4 times
