Speed adjustment

[jimalan1989]

So I have ordered a set of wheel and tires for my vehicle. And I know there is a speed adjust available with the flash pro. According to willtheyfit.com, I will have a speedo Difference 0.98%. With my speedo reading less then one mile and difference at 60mph. The wheel and tire is slightly smaller making the car think it’s running faster. I know it’s extremely minimal, but would I be correct by thinking to enter 0.98 in the speed adjustment box? Or is there a different calculation I am looking for? Again I know it’s very minimal but I really would just like to expand my knowledge on the speed correction and make sure I am understanding it correctly.

Yes you can enter it there, it will round it to a slightly smaller value, but that is how it stores the value.
