i will i ordered another obd2 to ethernet cable and will take logs on bm3 i believe it is my lpfp because before it was my hpfp not keeping up and now that i have the xdi 35 it cant be the hpfp it must be the lpfp failing for a second under high boost and wot pulls.

here are some logs from about a month ago before i got the xdi 35 hpfp installed

car is 2013 bmw f30 335ix n55 6mt wagner comp 2 intercooler, wagner catless dp ,afe drop in filter, er chargepipe, new delphi ignition coils, ngk 95706 plugs gapped at .022

any input on how lpfp is behaving?

i will post new logs with xdi 35 when i get my obd2 to ethernet

lpfp looks to be at 72 should it be higher?

I would open a PTF support ticket and ask the pros.

[13blk335ix]

yes i have, they have told me multiple things and i do them and it gets better but it dosnt completely go away. currently saving for a lpfp and a walnut blast.

You mean HPFP? The F-series has no LPFP sensor. Not sure what thos 72psi are but it is not a measured value - estimated maybe...

[13blk335ix]

i have an xdi 35 hpfp. i have a stock lpfp. it reads 72 for lpfp. i am looking at getting a stage 2 lpfp. any input?

I have a stage 4 lpfp and it shows 84psi.

[13blk335ix]

Rail pressure seems to be much better on the custom maps but not a horrible dip with the OTS map. I would assume with just the B58 HPFP the rail pressure would straighten out with the OTS maps.

The car feels very quick with the OTS maps compared to the Custom map but dont want to kill my HPFP just for a little more seat of the pants fun!!

Any feedback is appreciated!

And your point being............

point is that your hpfp is dipping with OTS maps with same boost, problems with hpfp or lpfp?

All this data is great but I would have liked to see a version without all the special fueling. Just a N55 EWG turbo upgrade with the appropriate mods running BootMod3 on 93 Octane. Does anyone have any such data?

most likely the HPFP is the culprit but not trying to break the bank and get the XDI-35 HPFP at $2000!

Log please! And who has done the tuning? Which version of the PS2 do you have - 6 or 9 blade design?

Chris @ Dervtech Tuning (UK) did the map, and I believe its the 6 blade PS2. Its a custom BEF, setup on a rolling road. I have a JB4 as Im playing round with meth now, but I dont think I have logs old enough that are representitive of the BEF without the meth.

Boost wise it peaks at 25-26psi and holds 21 at redline.

[13blk335ix]

about to take logs with the xdi 35 hpfp and custom tune. stuttering is back and just as bad as ever. i have new ignition coils and spark plugs. i am going to take logs with the stutter occuring and i am going back to ots bm3 map.

i have sent multiple logs to bm3 and opened up many tickets. they said my stock hpfp was dipping before so i upgraded to xdi 35. problem still exists.

i am on stock lpfp and i beleive this whole time my lpfp hasnt been able to keep up.

the week i was going to install the xdi 35 i reflashed the stage 2 ots map and wasnt experiancing the stutter. i still got new hpfp for ps2. i am on stock turbo.

my logs before were without xdi pump. the ones i am about to post are current stutter.

if there is still dipping in the hpfp it has to be my lpfp just cant keep up with increased boost.

and this whole time it has been my lpfp

JB4........... Hope it works better for you than it did for me. Are you running the latest integrated firmware? Have a few JB4 logs with meth to share?
