HELP!!!

[TommyInSC]

I have a 2017 Si Coupe and my computer hard drive is toast and it has the stock calibration on it. I just traded in my car and I need to reflash back to stock when I go there tomorrow. Any idea how I can unlock this thing without the stock tune.

You must return it to stock using the software. Go to the online menu and click on return to stock, after you have returned it to stock, go back to the online menu and click on unlock from vehicle.
