Will the dealership flash my ECM if i remove it from my car and bring it in? I don't have the stock tune saved and it is too cold and snowy to drive my car in.

I doubt any shop or stealership is going to flash the ECM for free. Even if you do bring it to them.

Very unlikely a dealership will mess with an ECM especially if you just bring it in.

What was your ECM flashed with to begin with? Surely the shop that originally flashed the thing for you will have a stock tune that cold be then downloaded to your ECM.

ECM must be in the car to flash it.

It will wipe out any aftermarket changes and install the latest calibration for your car.

Don't some bench flash the ECM?

My starter tune after I added my Supercharger was loaded on the bench out of the car.
