I3 unlock and/or new license???

Post by Eaglefan55 »

Hello .... I have an I3 tuner that i bought for my 2014 Camaro SS. Last year I traded the car and totally forgot to set the tune back to stock. Now I have a 2017 Silverado 1500 (5.3L) and I want to use my tuner to set up the truck. Especially since i am in the process of lifting it and I'll need the speedometer adjustment. So... how do I get this unlocked? and will it work on my 2017 Silverado (5.3L)

you can buy the $149 GM license then you'll need to purchase an additional $40 GM unlock after initially connecting to the vehicle since all 17+ GMs require a specific unlock.

I3 2016 Silverado Wrecked total loss. How can I get it unlocked or do I have to get a new license? I have no way to unmarry it! I want to use it on my 14 Ram.

I just got the DBS-8225-R for 2021 GMC Sierra. Do I need to buy the GM unlock as well even though it came with the ECM/TCM unlock cables?

Thanks. Now to figure out why it’s not updating cleans keeps saying the truck is not supported. I’m wondering if I got shipped a malfunctioning unit.

Would it matter if I had originally started on a pc but then after getting the registration done and attempting the first update done. Then switching to a Mac do to the pc crashing later? I would call but the truck and tuner are an hour away and by the time I am home the line is closed.
