Yup, it's way down there in the menus. If you find 'Sport Individual' settings, you can select Normal or Sport for Suspension, Engine, Transmission, and Steering and save that configuration to your profile. Then you can choose Sport, Sport Individual, and Normal in the selection pop-up...
Yes. you can do that. Configure Sport Individiual to the settings you like. Suspension -> Normal, Engine (exhaust) -> Sport. Then use BimmerCdoe to start the car in Sport Individual. That'll get you the settings you desire.
it doesn’t remove CEL. You can run a pure800, but you won’t get anywhere near maximizing it. You’ll need fuel modifications to do that. Leaves you with a stand-alone for fuel management - I’d advise against.
Well, ok, sure. If you want to call the piggy back a tune sure. Most people don't consider it a 'tune.' I run a JB4 w/ with meth, JB4 is tuned by DaBears, I wouldn't consider myself having a tune, most people wouldn't. But, yes, pedantically, you're correct.
Oh, I might change my answer if you're going to daily this thing. is this car a steal for a race car at < $50k? Yes. yes. it is.
If this car a steal for a daily at < $50k, ehh, maybe not. Have a reputable tuner shop check it out before you pull the trigger.
Hitting the rev limiter too hard will send you into limp. Shift manually and at ~5800 with the stock turbo, especially if you have a tune. Look at the factory dyno graphs, you're maxing out the turbo and blowing hot air at that point anyway. Powerband dies at 6k rpms.
It’s kind of a pain to trail it back. I was going to do it when I swapped the charge pipe but never did. Just zip ties it. It’s also just on the intake, it wouldn’t affect revving at all. You might be having other issues.
