Rail Pressure Collapse
Last night I went to get a datalog as I am trying to diagnose a 29E0 code that I have had for the past few months and when I was about at the end of the pull my rail pressure collapsed. My HPFP seemed to have shut down or something because my rail pressure was nearly equivalent to my low-pressure sensor, correct me if I'm wrong. When this happened, the car went into limp mode and I received these two codes: 29E0 Mixture Control and 29F1 Fuel pressure, plausibility. From what I have seen, 29F1 is caused by fuel pressure instability and people have solved their issues by replacing the LP Fuel sensor and HP sensor. I have already replaced my HP sensor a few months ago, so considering that could it be between the LP sensor and HPFP? if you guys would, tell me what you think. Datalog attached below:

Hi all. 2006 335i auto XHP stage 2
Trouble shooting a misfire WOT above 6000rpm since getting catless downpipes and ots stage 2+, anyone help appreciated. First time it misfires was clylinder 6 and second time cylinder 1. For the past 8 weeks I've noticed a rpm drop at low revs off load, you can see the rpm drop on the 4th log. Could this be related to the high rpm misfire ? I've had the wastegate flappers rebuilt in-between the rpm drop and doing catless down pipes and 2+. Mods - forge intercooler, twin cones, charge pipe & bov, 3" downpipes, scorpion rear exhaust boxes, oil catch can. New Eldor coils & genuine n54 bosch plugs within last 500 miles. -First log shows the misfire. -Second log is after resetting all adaptions but didn't misfire. -3rd log is WOT TC off 3 pulls before I got check engine light @6300rpm -4th is off load low rpm and shows the rpm drops https://datazap.me/u/335icoe/misfire...og=0&data=3-22 https://datazap.me/u/335icoe/after-m...og=0&data=3-22 https://datazap.me/u/335icoe/3rd?log=0&data=3-22 https://datazap.me/u/335icoe/rpm-dro...og=0&data=3-23 What does the stock tmap sensor max out at and should my load be above load request? Any help appreciated I'm thinking about cleaning the tmap sensor and Changing plugs to NGK 1 step. Thanks Last edited by 335icoe; 04-21-2023 at 01:10 PM.. Reason: Missed info |

Put it in manual 3rd gear, get the car around 2-2.5k rpms, and then floor it, not letting off until 6k rpm. Shift into 4th then you can let off and stop the log. This is the only way you're going to get all the info in a way that's reasonably easy to decipher. |

I am new to uploading post but am familiar with this site plz be lenient, Okay, Ive been trying to figure this out for months on ends now, My car is currently on all correct supporting mods and Maintenance for what I am trying to achieve. My car performs perfect during start up and just normal daily driving. Now once I get into boost after doing a few test runs. It will cut out aggressively under boost. Ive heard about the EKP overheating so I applied thermal pads and still didn't make a difference. This log is the worst case I had and just wanted some help. I am convinced its related to fuel, heres the log. I am currently running a e50 mix on upgraded 17ts and inlets. with all supporting mods.

Just finished rebuilding my motor and got it all installed but having some stumbling issues. I’m assuming it’s either fuel or a vacuum leak. Keep getting lean codes and vent valve error codes. Tell me what you guys think.

Did some logs on the way home from work. Gtg or are there issues you guys see?
https://datazap.me/u/mpayuyo/coming-...og=0&data=3-22 This one is just normal cruising: https://datazap.me/u/mpayuyo/commute...og=0&data=3-22 Will be changing out injectors 1-3 soon as I just recently did 4-6 last month. Starting to get hiccups and rough idle/ 29E0 codes every now and then.

Excessive Timing Corrections
I've had this issue for a couple of weeks now while running MHD V10 Stage one 91 octane tune, I have timing corrections out the wazoo and STFT all over the place. I recently replaced spark plugs with the oe bosch ones and it didnt really change anything. I know the fuel is up to par because I put BP 93 octane and octane booster in it, also been running injector cleaner for the past few tanks. I've reset a couple of adaptations to see if it would fix it but to no avail. Car has index 12 injectors but idk the condition they are considering one of them ticks really loud. The car only has 80k miles.
Can someone please point me in the right direction? This is sort of throwing me for a loophole. I can provide other logs if necessary. https://datazap.me/u/niteryder/log-1...7-8-9-10-11-20 |
