Carbahn standard vs EVO tune
I’ve searched for other threads but haven’t been able to find one referencing this topic.
I have a 2018 M550i looking to ECU tune. Does anyone have experience with or know the differences in the Carbahn Evo tune and their standard tune? I appreciate any insight. |

That's interesting. Any word on how it works? I believe that the BM3 Flex-Fuel tune uses an ethanol sensor but maybe Carbahn just keeps advancing timing until it senses a knock? Honestly the latter makes more sense since octane is ultimately what matters, not necessarily ethanol content.
