Additional licesce

[Mittermax]

Hi, I’m new to the forum. I just purchased a used trinity 2. I plugged it into my vehicle only to find that it was never unmarried from the last vehicle. It says I need to purchase an additional license. It was a really good deal… Now I see why. My question is if I purchase a custom tune from hemifever, will that act as an additional license?… Or do I need to buy both? Thanks in advance.

the license is needed to be able to read/write the vehicle, period. The custom tune is simply an additional tune you'd purchase after you added the license.
