I have the V2 & would like to know if i can flash a tune from my laptop to the V2 device & then load the new tune into the car like that? My laptop battery is shot & won't hold a charge long enough for me to do a flash. I'm finally finished working on my car for now & would like to have the speedometer be correct. It's probably going to be a week until I get the new laptop battery also. I do have a SD card that has the tune on it that i want to flash into my car. Is doing this possible & if so how?
