Stalling N57 under WOT

Bull3t Proof · 05-07-2020, 01:43 PM

Hi Guys & Girls....

I have been knocking my head senseless trying to figure this out...

Modifictions - Hybrid Turbo, L93 Fuel Pump, M50d Fuel rail sensor, Cooler, Full Turbo Back Exhaust.

Problem : Car will not accept Fuel rail Pressure 2350mBar and above. Anything higher than 2350mBar - car stalls under WOT.

I have seen a few thread, however they differ to my experience.... anyone have knowledge of limits on CP09 that can cause this?

It’s shutting down because of the rail issues. But you already know this. Are you sure on your units? 2350mbar is 34psi. Can you give more details on the car and your setup, tune, etc?

Any specifics you would like to know?

Which is best way to view injector values?

Modifications mentioned above. Tuned for 2.8bar boost, 105mg, 2250 rail pressure.

Want more rail pressure because i have the L93 fuel pump. So i can pick up boost.

But struggling to find more rail limits.

Sensor is only good to 2200 right?....using one on my M57. IF your on facebook, the DUDMD guys are tuning them might could ask over there, or look him up. Good luck.
