I decided to cough up 270 bucks for the module. Won't be here for another 5 days or so according to Ecstuning.com, I just hope this fixs the issue. 8psi isn't fun at all when at one time it was at 23

Update

New module arrived from ecs, coded and programed to car with latest ekp software from bmw, after 30miles of driving fuel pressure still at 55psi. No codes, no issues starting or idling or driving normally. For this reason I can't upgrade to any pump bigger than oem. Currently on the original bmw fuel pump and still not getting right psi

You do not need 65psi at idle, I don't know why everyone is so obsessed with that.

Running a Stage 2 pump allows the DME to retain control of the pump via PWM, consequently it may and most likely will show lower pressure at idle and cruise. Running an inline pump removes much of that control from the DME, thus the higher pressures. Higher pressures do not equal more flow, nor is more flow or pressure needed.

Our N54 has a very powerful LPFP setup...it runs at 60psi at idle and cruise with an external FPR. You can't even set the FPR higher at idle than 65-67psi as the DME will pull PWM to the pump and won't allow it.

Complelty understand, but the fact that the more throttle that is applied you would expect pump voltage to increase and pump more fuel and at the same time increase the psi when logging. But I personally have that issue with any setup higher than a s1. It would increase the pressure barely, 3-6psi. After everything was replaced that sounded like it was bad, your telling me during a pull in 3rd that 62-57psi through out a run with a S2 pump and 19psi on e30 was maxing out my system. Just doesn't sound right to me. Than id throw a S1 in there with a brand new lpfp assembly and run E60 at 25psi and maintain 78-66psi through out the run.clearly a S2 flows more than the s1 and oem setup should but it didn't seem like it

Is this when running e85 mix? Because I see 65psi at idle and wot. Stock ecu. Stock lpfp. Only hpfp has been replaced.

hello i've done close to 100 installs stg 1,2,3 and been on this forum since the only thing available for the n54 was the jb+ and never seen an issue like you..

now, dont matter what fuel pump you install the ekp module(fuel pump module) is the one that controlls your lpfh & hpfp so thats still alittle issue there.. but of course upgrading to better fuel pumps will help mantain your fuel under WOT.

one thing i hate about people is:people making statements about a product that they think dont work .... bcause thats what they think its the issue but is not..

solution:


#1. ask the seller for a replacement.. maybe it can be defective.. sometimes even new products come defective .. i experience this even on oem spark plug,conectors etc coming defective....


#2 update the jb4 to the latest. double check all your setting .. make sure you have all your setting right... the correct flash/backend flash/mhd flash/cobb whatever...

#3. log your car and check all the parameters... lpfp,hpfp,trims,timing,fol,waistege position etc

once you see the log then you will see whats wrong with it

stop been a lil Bitc. and stop accusing a product you think is bad . because thats your own opinion.

Looks like you missed my other thread. Everything was done, I'm asking for assistance. Logs don't show any issues, since than I sold my S2 setup as it wasn't worth having as I couldn't use my car past 16psi. I also have done multiple installs of pump and just did my 4th turbo install on jackstands, so I know these cars pretty well now. I'm trying to get some pointers in the right direction and go from there

I don't know if you have more posts on this but has all the wiring and grounds been checked for the EKPS and the fuel pump. Also check the terminating resistors in the PT-CAN for that system and make sure they are where they should be. Check all lines from the fuel pump to the rail, make sure you have the updated fuel pressure sensor and not the old one. Old ones are ****. No fuel seeping out of the rail or anything, check connectors for the fuel pump. Id just go over everything with a fine tooth comb.

I have the fuel it upgraded lines in the trunk I have to install so I'm sure that will help. As far as the lpfs. What does the upgraded one look like? I replaced it with one that looked like the unit that was on there.

It should be silver and it should all come together with a hard line and sensor together as one piece.It has a quick disconnect on one end with a fitting into the HPFP on the other. The gold ones are el junk. Ive only been able to find the updated one straight OEM from BMW. When i look on turner or even REALoem, they still show the old gold ones and they don't come together with the hardline. Im not sure what the whole deal is with these, I work at a BMW dealership and the only ones i get from parts are these updated silver ones but i still see the old gold ones everywhere online. Its weird. Ill try to take a picture of what the new one looks like on my car

From what I saw online that hard-line is part of the hpfp assembly,so I would have to buy a complete set in order to receive this hard-line(minus hpfp). And I think you are the 3rd person now that has mentioned this line

Yes, I believe a brand new one has to be coded for your car. I added a 4x4" aluminum heat sink to mine and have had no issues with fueling systems since. I haven't measured temps before and after, but both EKP and heat sink feel cool to the touch. It's a plate that partially slides under the EKP. The tension from the mounting bolts holds it in place. Kinda redneck but seems to work ok. Car has Stg 2 LPFP and RB turbos.
My original idea was to get a 6x6" heat sink and cut the fins out in the center to create space for seating the EKP, but that would require tools I don't have access to.

The EKP module generates heat and has its own built in heat sink plate. No fins though, just a thick aluminum plate. When we upgrade to pumps that draw more amps than stock, the EKP works harder and overheats. That is my guess at least and why I added a bigger heat sink to help the EKP run cooler.

Please post pics and where do I purchase 4x4" heat sink from?
Did you use thermal paste between the ekp aluminum plate and your heatsink?

I'm in the same boat. I was idling at 57 psi for several weeks. I decided to pull out the Fuel-IT Stage 3 pumps to change out a fuel level sensor. I uninstalled all of the wiring to check for any tears are poor connections. I reinstalled with no change in lpf at idle and during WOT, the lpf would tank down to 38 psi. The next day I pulled the Stage 3 pump for a second time and re-installed all the wiring for a second time out of frustration thinking maybe something wasn't on tight enough. Anyways this time the lpf at idle jumped to 83 psi and then settled down to 65 psi. However during WOT, although the lpf is tanking down to 38, it is still tanking to about 50 psi. I also installed a new lpf sensor recently and it didn't change a thing. I have now resorted to ordering a ekmp module to try that. My logs show that port is turning on and the trims are good so that tells me that both pumps are turning on and working. This is all very frustrating as a 5 months ago, my lpf would not drop below 70 even with boost at 30 psi.

I'm hoping that someone could chime in so that we can resolve this issue. Are the Walbro's starting to fail?
