Hello everyone,

I've docrace 6266 on my F30 n55 ( 2013 PWG ) since 2018, and the driveability is not smooth although no Codes or anything. my BEF supposed to be MAFless tune but AFR jumps randomly at low throttle, not sure if there is something wrong during the installation or something else.
Have anyone ran mafless successfully on N55 Fseries?

mods: FBO, JB4 + Twisted Tuning BEF.

Interesting. I've wanted to do this with my set up as well just to get rid of a bunch of stuff and clean things up under the hood.

I'm almost positive I've seen it done but can't remember names at this point.

Anyway, I'm following along to see what you come up with.

Funny i see this now. I actually have something to send you. Well, not yet, i have to transfer it to your ROM type. Been messing with some stuff on my N55 in regards to the whole mafless thing. Give me a day or two to transpose to your ROM and then to your custom map.

Cool, we just have a new Track in our Country and having tons of events this season.
I've been thinking of selling the car and wait for something in 2020 but maybe not yet if the outcome is satisfying.

The main benefit of having a MAF in combination with a MAP sensor as opposed to running straight Speed Density (MAP only), is to eliminate the condition you describe above. SD alone is never going to be able to have perfect fueling during small throttle transients.

That's only cars that originally have maf right? Or that applies to n54 as well?
