Hi,
I'm sorry that I did not reply sooner but it gets so busy that I don't get a chance to log in as often as I'd like. You may have already gotten a response to your question but ...
If you have your old strategy or maybe you could ask your tuner for it, you can compare your old strategy with your new one and that will tell you.
Also, the X3 unlocks itself. These instructions are only for the Xcal2.
Let me know if you have any questions.
Thanks,
Vivian
