I’m starting to think the factory bmw tune runs things as lean as possible with aggressive timing for max efficiency making it close to knock as is. Then you throw in the fact it’s not running on 93 octane. Also the 91 in CA is even worse then the rest of the countries fuel.

can you try to explain what knock sounds like.. does knock happen 24/7? at idle? only when hot? etc..
im just trying to know more and understand better in the case i get this bc every video ive seen on f10 knocks, im not sure if it is actually knocking, bad vid quality, etc
