...Not sure what you mean by unlocked. Can you explain?
Every tuner manufacturer makes their tuners lock to your car or truck in order to prevent you from being able to use one tuner on many vehicles; it's their way of making sure they get paid for every vehicle out there with their tuning on it. Basically, when you program your vehicle the tuner will read your VIN number and store that number inside of it. As long as that vehicle has the performance tuning on it, the programmer will only work on that vehicle; if you try to program another vehicle you will get some sort of error message and programming will not be possible. Once a tuner is used to install performance tuning on a vehicle, that tuner becomes "VIN locked" or "married" to that vehicle. However, once the original vehicle is returned to factory settings using the tuner, the programmer “unlocks” or “unmarries” itself from the original vehicle and now becomes ready to be used on another vehicle and will function exactly the same as a brand new tuner.
Is this still for sale? If so how well supported are these in 2020? Are they out of date or can still be used?
