That's such a silly way to look at it.

Once it's unlocked, it's unlocked and some folks seem to be getting close.
I think realistic rather than silly, go back through the thread, the numbers of guys who have said it will be unlocked soon, mate has had his unlocked etc etc etc, still hasn't happened

Don't get me wrong I hope it is unlocked, a tune brings so much to this car, but the reality is it hasn't yet.

This isn't a "Supra only " issue, there will be plenty of companies trying to achieve it, think of the number guys lining up to get their cars tuned, goldmine right there :)

RKTunes are saying they have unlocked 6/20 ecus
They aren't actually. They're saying they can generate a passing signature for the ECU file. When you get the ECU back it will not be unlocked, it will have new software on it.

What is the difference for the customer? Will this new software on the ECU still allow it to function as an unlocked ECU?

No it means they figured out how to write to the ECU but its a new program and thats it.No changes without sending it to them each time.

Big difference. A custom tune "should" have several revisions and tweeks along the path to final tune. And then down the line you may want to change something because your style of driving or how you race has changed. Each time you would have to mail them your ECU

Glad someone is making progress
