LOL yeah right. It tries to adjust after the knock sensors light up like christmas trees. It backs off, and tries again, and again, and again, and again to achieve the timing it was programmed for. That's why the engine isn't destroyed almost immediately.

What do you think aftermarket "software" is doing? LOL. Now you're relying on some random guy to get it right instead of a team of engineers at BMW. Judging from the maps I've seen in person, they get it wrong - a lot.
