BMW Tune MPG
Recently got my car tuned, and went catless, I got both a transmission tune and ECU tune. It is mapped for some burbles/noise but not a lot at all. I’ve been driving it for about a day now, maybe 20 miles in total, 5 of those being in sport, and I’m averaging 10mpg LOL. Will the tune eventually learn and I will get better gas mileage or am I screwed?
Thanks |

I am also guessing the new tune is causing you to have a heavy foot. I think once the "newness" wears off you will be less inclined to test it. Give it a few weeks then recheck your numbers.

It's because of how you're driving. Mog when not in boost isn't effected.

I am 100% sure the tune isn't giving you bad gas mileage, especially with such a pitifully small sample size (20 miles). I was getting worse gas mileage right after I tuned my car as well. It will pass.

As stated above, tune shouldnt affect cruise MPG, unless you have some weird tune(er).
It's using sport mode and your right foot that are affecting MPG. Once you are tuned you generally need less throttle input to achieve the same speed and you are probably using the same or more. |
