Wheel alignment/ tuner question

[bigmoneycloser]

This may be a Dumb question...
Does a dealer have to plug into the computer(where I upload my tunes) for any reason while doing a wheel alignment?
Would they notice my tune if they did?
Thx

I don't think so but, I always flash to stock before going to the dealer.  If they have a bulletin to reflash your computer and just do it with out telling you, you could be screwed.

Quick question?
What would happen if a dealer flashed my computer with a custom tune on it?
Also, when I flash back to stock, do I have to disconnect battery? LMS says too in their directions...
Thx

I'm not sure but I think if they update your ecu it is based on the stock tune.  If you have a custom tune in there, the update won't relate to it.  Plus your stock tune stored in the programmer won't get the update.  I have heard both sides of disconnecting the battery.  I didn't last time I went in for an oil change but, it does sound like a good idea.  I just try to play it safe and flash to stock whenever I go to the dealer.

Good idea.
I will do as well.

I am hardly an expert on tunes.  I do have some experience.  I just try to play it safe. It only takes a few minutes even if you do disconnect the battery, to swap tunes.  I didn't do the battery last time mostly because my sockets are still buried from moving and I was too lazy to look for them yet.  Good luck with the alignment!
