SCT Livewire

I found a SCT Livewire Ts forsale for cheap. The question I have is, when he unplugs it from his truck does the tunes stay on it. My truck is down and the injectors getting rebuilt so testing on my truck before I buy it is out of the question. He says it has 1 custome tune from Eric. Any advice is appreciated. Need to know ASAP.

SCT Livewire

Make sure he returns his truck back to stock tune. If he leaves in ANY aftermarket tune from a SCT, the SCT becomes "locked" to his truck. Make sure it had "unlocks left", the SCT has 5 "unlocks", every time the SCT is tuned to a different truck/car VIN, it uses a "unlock".

It's wise NOT to use his custom tunes.

You can use any Ford truck or car that is CAN supported to check the SCT device for "unlocks left" and if it's "unlocked.

Here is some reading material on buying a used SCT device.
What to look for when buying used SCT for 6.0

I assume all of this information applies to the livewire , 3015 etc. If the previous owner
did not return to stock and you connected to your truck , you would only loose 1 unlock
correct ?
I also purchased a 3015 from a member on here . It"s a "Gearhead (Matt )" 3015 that
holds 10 custom tunes (it's supposed to be a non race 6.4 version that does not have
dpf delete etc.) . It has 3 6.4 custom tunes on it , and 5 unlocks left and is unmarried .
We purchased it to use on a 6.0 and don't no where to go from here .
I'm afraid to actually hook it to the truck for fear of it never starting again .
Sorry for the hi jack OP , thought maybe we could learn together

You only use up a "unlock" when you go to tune the truck/car. Every time you load a tune in a different truck/car the SCT recognizes a new VIN. The SCT only stores one VIN at a time. So if you own a 6.0 and a mustang, and try to tune them, you will use up the 5 unlocks between both vehicles after 5 attempts. You can check for codes,monitor, and look at "unlock/married" status as many times as you want with as many vehicles as you want.

SCT says that the 6.4 uses different Firmware and I believe different hardware than the 6.0. You can read this right from SCT on post #43 and #44 in this thread.
