    frontside0815 replied to a thread Fueling on hybrids in N54
    Me and a friend had a similar Problem- LPFP Dipped to 50-60 with my custom Walbro 450 (so comparable to fuel it stage 2). Then HPFP crashed and trims maxed out.... Because our tuner said that he had like 10 customers who all had Problems with the walbro 450, we switched the 450 for a fuel it stage 1 (OEM Bucket + 255 Inline). Now all Problems were gone for both of us! I wouldnt recommend the 450 anymore...I dont know if that helps you, but you maybe could try another pump... I actually changed everything from HPFP to INjectors, fuel lines etc etc. But in the end only the LPFP "Downgrade" helped!

    INPA has it, but it didn't find my module. Maybe it will work for you, but I used Tool32. It was steuern reset IIRC, there's also a null reset IIRC, no clue what that one does. I can see there were target changes in those logs, no changes in the BEF too between those runs? A lot of things can change trims and you have a lot of variables in the mix, meth is just one. There are some sizeable differences in FOL between some of those logs, but note that both pumps look better at lower FOL, yours and the before/after above. I think the trims need to be addressed in the BEF to keep FOL at a reasonable level. Where the trims peak, AFR seems closer to 13-14:1, but it's hard to tell on screens. From the log in the OP though, it doesn't make it above 13:1 until almost 6000rpm. Might try fattening it up where trims are remotely close to 50. Trims drive FOL supposedly. Constantly high/pegged trims cause a fake a low HPFP reading to the DME, which in turn, supposedly commands more of the LPFP. So you've got a current-heavy pump on the EKP and JB4 keeps telling the EKP to push it harder. Problem is, it's asking more and more of the pump/EKP, but the problem (high trims) never gets resolved and they cycle continues until you've pegged FOL, which you have. At least that's my take on it. :) Anyway, adding AFR in lieu of letting the DME trim it up won't solve an actual fuel shortage, but should stop the JB4 from trying to force the pumps/EKP to do more (which it seems they can't). Of course, the other things you can try is dropping the E content a bit or getting meth in earlier, but relying on meth for fueling could be an accident waiting to happen.

    Wow. Thank you for your hard work on this. It is truly a service to the community. Unfortunately I'll have to wait as I have a N55. I will help in any way I can when it get's to that point. I don't know anything about writing programs. I wish I could help more as this is really an awesome thing.

    By strainer/filter do you mean the plastic insert? And how did you remove it?

    i thnik for most of the people here is easier to buy something already tested and bolt-on rather than spending time in a garage and making your own at lower cost. some are enthusiastic, some not, some just dont have time to go with all of that stuff. TEC did a good job and hopefully his efforts will not leave unattended.

    Yes and I just did this. I'm now on INA0S not the old build. Pretty slick, only took 24min too. I'll be ditching the JB4 setup and going flash only for this car. Anyone want a JB4? How about a really nice super well maintained 08 e90? Hahaha

    The rail you can easily drill but do it off the car, and remove the strainer/filter as that's the biggest bottleneck Most people run without a filter and had no issues, personally I wouldn't.

    Man a million dollars would be so awesome. I would invest most of it in something safe with moderate returns and try not to touch it for as long as possible.

    I've used the prometh pumps on other cars and it's kept up with 3 10gph and 2 3gph. So 36gph of methanol.

    I have been hearing some good things about this pump.I have spoke to Rodney Michels from PRO Meth(aka Alcohol Injection Systems). He has told me some neat tricks for better flow.His pumps are made different and tailored to ProMeth only specs.Cant verify that but some tricks were: -the inlet of pump by dremeling the inside of head for less restiction -also from tank to inlet use a bigger line instead of 1/4' OD -tank screw cap to drill out bigger for systems that use alot of meth for less restrictions.Either a check valve or run a line to outside is recommended to avoid fumes. I think the less restrictions from tank to inlet of pump will help the pump on delivering meth easier with less work.

    Dont think we would hit 300 psi anyway.Thats from what i was told from Meth heads out there.

    The proof will be in the slip. You're going to run a 10.5 or better.

    Just a little feedback on the GCs from an end user. They are great.. I have 3k miles on them without any issues, they spool well and really breath/pull up top. I am still tuning the car as the DCT swap+shotgun pump are a little less known but its coming along well. the car rips on 26 psi... inb4 someone call me a shill, I am sponsored by vargas. That said I am not saying this just because. These turbos can speak for themselves. o and they sound pretty neat too :)

    Sounds like the 300 psi pumps are the same as the 1.3gpm pumps but just claiming the higher pressure and lower flow rate. Have you tried a flow test? Just calculate what flow should be per minute and then do an unrestricted flow test with just the pump and some hose for say 10 seconds. Flow per minute divided by 6. Use some measuring device. A cylinder, a measuring jug. Whatever.

    I didn't sell at 400, and I have bought more in the dip. My sell price is 1000. It's going to hit it. I'm aiming to be a "millionaire" I guess. I just want to see a 7 figure pay day. Which isn't even enough for me to retire on. Half will go away in savings or other investments, the rest will be spent on a house, car, bike, boat.. whatever I want to buy. Fuck a Ferrari, maintenance cost alone would break me. lol

    So is this located between the hpfp and low pressure line? I'd like to drill this out first as it may take a while to get a low pressure hose.
