Fuel starvation solutions?

But anyway, if it isn't listed yet it should be soon. And it's not a crazy expensive solution either.

We've been pushing the topic since 2019 and finally, light at the end of the tunnel guys!!

wow. super looking forward to this.

Definitely looking forward to seeing BWs solution.

Any update on this ! Sure would like to run less fuel in the tank, given how heavy the car is.

When this happens are you getting a misfire code?

Just to throw an update out there, we (BimmerWorld) are still working through the solution and have a few test kits out in the wild with some that have known fuel starvation. The results have been mixed, definitely an improvement on some, then didn't seem to on another, so we want to understand what may have been the issue on the one that it didn't seem to help before putting our stamp of approval on it. Obviously this time of year the track time has slowed down for many, but we do have some other testing that is supposed to be done by the end of the month. So hopefully around the end of the month/early March we'll be able to give a more complete answer here.

Woohoo!!! Cannot wait!!!

I say it's better to do 100% testing and delay the launch than release an untested solution

[E92inSG]

Would this work?

And someone else has suggest fuel tank anti-slosh foam as well

I experienced fuel starved limp this past weekend at Barber. After turn four rise where car is unweighted under strong acceleration towards turns 5/6 on about 1/4 tank or little more of fuel. 2018 F80 CS on R7s. My buddy did also a hour later in same spot on track, in a 2017 F80 base on NT01s and roughly same fuel levels. I went into limp while his car stalled in addition to limp.

Fortunately neither were in a crowd or tight passing situation when it happened. We'll be fueling up more frequently from now on, but would be cool to see a solution for this issue.

Every M3 before E92 had this issue. Common fix is BW dual pump setup (which is almost always on backorder) but not sure if they sell one for F8x.

i get it consistently after the a long high G right hand corner. engine cuts on accel out. but also running E50-60, which is demanding on the fuel pumps.

Would love to do a surge tank as soon as a kit becomes available.
