Once an ECM's number is entered into the SCT Tuner, it will never be able to be used on another vehicle. They were designed that way to ensure more sales.

If you really want one, you can buy one from Performance Injection Equipment. They can dramatically improve performance over a stock tune and are very flexible for tuning performance builds of all description.

Ask for Chris. He is a great guy to work with for writing performance tunes. All you need is a wideband to give him feedback.
