I'm interested however two questions
1. Does this affect the BMW 3 year warranty if something goes wrong with the engine?
2. Is this something you disclose to your insurer and if so how much does it add to the premium

I would be very surprised if the warranty isn't void and if you have an accident and haven't declared this modification your chances of being covered are reduced possibly to nil.
That said, the insurers are very unlikely to find out unless it's a very nasty accident - I have never heard of any insurer interrogating the car's software
Not sure how BMW would cope if they had to check every map on a car at a service interval, again if the turbo goes for example and BMW AG ask for more info you could well be stuck.

I'm on a couple of motorbike forums, and the discussion of remapping comes up regularly. I have had my bike done, and declared it to the insurers, and it made no difference to the premium.
If anyone gets a remap, make sure you tell your insurers, as I read of a case where a bike rider killed someone, the insurance company took the ECU apart and found that it had been remapped and the owner hadn't declared it.
The guy ended up losing everything, as he had to pay the family of the deceased, the uninsured damage to the bike and car that he hit, plus the associated fines.
He was particularly unlucky, as the person he killed was a high earner, so the judge made him pay an even bigger sum to the family, due to loss of future earnings.
