Hi CG,
There is no timeframe involved at all, you can plug in that Micro Tuner as soon as you get it and check to see if there are any codes right away.
However, if there are no error codes present, then you won't be able to see any codes with the Micro Tuner or any other code scanner because they don't exist. Which is what you will usually find, by the way, unless you have a Check Engine (SES, or Service Engine Soon) light showing on the dash.![Smilie](https://www.f150online.com/forums/images/smilies/smile.gif)
Have fun!
