So then, I'll ask again!
Why not just get an ECU, same make/model from pick & pull or wherever, and swap it, flash that one and preserve the original in unmolested state. Then if there's a problem, a simple swap back to stock is all that's needed. No? What other modules, record and store information? That is the question...
As for XHP... I can't see how changing shift points and maybe line pressures would void a warranty unless torque protections were disabled. Just my $.02...

Having an extra ECU to swap in and out sounds great. I'd imagine an ECU to be a decently expensive part though, and I'd assume that BMW would be able to find out by checking and referencing dates. XHP does raise line pressure and torque limits. I would assume that a dealer would not honor the warranty if they knew XHP was installed.. the question is.. can they tell??
