Hi gents!
After 2 days of spirited autobahn driving with lots of 100 to 200km/h pulls, just as i was almost leaving the autobahn, i could no longer ask for any power.
With more than ~20% throttle, the car starts misfireing and if i don't back off quick enough, the car goes in limp mode.
I quickly got my odb cable and MHD app i started realtime logging. When i pressed the pedal, the lowpressure fuelsystem starts to lose pressure and the hpfp follows.
I then ran a log; https://datazap.me/u/ballistic/bmw-n54-335i-e91-autobahn-driving-no-fuel-pressure
I recently upgraded to a Walbro 450 lpfp but stuck with the EKPM3 thats in my car. At this moment i am blaming a fried EKPM so i already purchased a 2nd hand from Ebay.
I let the car cool for a few hours but the problem stays.
What do you guys think? Is this typical fried EKPM behaviour?

No ethanol in tank during the problem.
