Just ordered a fuel it stage 2 lpfp for my 535i yesterday. My goal is to be able to run enough e85 to get to 100 octane which is around e60. Ive been running only 4.5 gallons e85 and the rest 93 for the past year no problems. Has anyone else installed the stage 2 on the f10?

Have they tested it to fit on a F10 yet?

According to steve from fuel its made for the f10 n55 and they sell them its just not on the website. How many they have sold, i dont know but mine isnt the first

Weird, because if it has been tested they would have it on their website dont you agree?
But looking forward to your testing and see how much more E you can run on LPFP upgrade only

I was under the impression that stock lpfp cant keep up with running high amounts of e85 so the hpfp burns up. Therefore upgrading to stage 2 would be the solution until the hpfp is maxed out. Is this correct? And if so now the question is at what point does it max out? Im gonna start at e40 once its installed. Hopefully i get much higher

Fuel-It should answer this
But most 535 are running up to e40 without upgrading LPFP

The LPFP is just providing volume, the HPFP ramps that volume up into extremely high pressure (1500-2700PSI depending on load)

Its not going to really cause damage to the HPFP if it isn't supplied a sufficient amount of fuel, and it'll "crash" when it doesn't have the volume it needs resulting in misfires, codes, poor running etc.

The stock LPFP on my car seems happy at ~470hp the highest peak I've seen. Alex MissionPerformance and I are still pushing.

It is on my upgrade to do list at this point, but I don't see a reason why you would want to upgrade yet unless you've upgraded the turbo. The engine isn't going to be particularly happy at E60 without a tune to run it. Look forward to fowl cold starts and poor cold drivability.

My only reason to upgrade was so i could run enough e to be at 100 octane and switch to map 7 on jb4.

What are your logs showing with your current E85 blend?
FP_H , Trims, for example ?

Holy hell, I just saw your youtube video with the X4 in your sig....BootMod3 is starting to look more and more appealing.

Fh_p stays from 12 to 14. Trims stay in low 30s

Thanks, that video was on beta v12 and now I'm running v13 since Christmas now, will try to get some good comparison once weather clears up

Since I am part of the Beta testers we went thru revisions 2-13 adjusting and tweaking, improving each one and testing limit via remote logs
