lpfp

I have a 2010 535i n54 and have been running a custom tune for pure stage 2 turbos for a while already. I am finally getting around to upgrading the stock lpfp to a walbro 535. I know it won't be optimized or request more boost, but can existing tune handle the new lpfp or is it highly...

I want to add port Injection to my car, I bout the Precision Stage 3 LPFP dual Walbros. and it says it comes with the wiring and Hobbs Switch. Would I need a secondary fuel pump control module Aswell? or does that come with it? Do I need to buy anything else to support the ported injection? Here...

Hi ! On IJE0S, i search tables for LPFP PWM and all others tables like PID if it exist pls. I have Walbro 525 with EKPM3 + active fan. My target is stock (72,5psi) in the table but my real pressure is currently 65s and sometimes it goes to 60, 58 . I'm starting to worry about my HPFP. I would...

Hello fellow BMW enthusiasts! I am running into an issue with my F32 randomly going into a limp mode and shutting down the engine shortly after. In the majority of cases, I am able to start the engine and drive after clearing the error memory. These are all the errors from different...

hey all, what's the best lpfp upgrade running on a stock ekp? I've seen that some folks even have voltage problems running a walbro 450 - let alone a dw400 or wb525; although I'll only be running 93 pump so my flow probably won't be as high as it would be with any ethanol. fuel it has a stage...

Then one day would crank and no start. Lpfp is not getting full power. Ive tried 3 EKP modules (coded...

All, I’m selling a brand new Precision Raceworks boost reference controller (Hobbs switch). Came in a kit I installed but I ended up going with a BPM4 controller so do not need it. Asking 40 bucks and shipping depending on how much it is. Located in 80211 I would be willing to do a local pick...

Disclaimer: just got the whole shebang installed last weekend, currently investigating some minor hiccups possibly EKP related. Will post full DIY when it's fully sorted. Is working fine now. About 3 weeks ago I started putting together a DIY stage 4 fuel system. My goal was for this to be the...

Hi guys, recently my stage 2 pump wasn't keeping up on E30 and around 22psi of boost on GCs. It was diving to 49 psi which in turn dropped the hpfp as low as 5 (750 psi) sometimes. One product was suggested to me but when I looked at it I thought a DIY looked better. I bought a hydramat for...
