Im trying to verify that I have a HPFP problem. All of a sudden I'm getting long crank it starts but its very rough idle in fact it stalls. If I give it a little throttle it will rev normal sort of but as soon as I let off the gas it stumbles bad and stalls. Eventually it will throw codes 29F2 and 2B2C (HPFP faults) .
Please check this log on startup. What should rail pressure be at idle? https://datazap.me/u/curt/lpfp-issue?log=0&data=3-20-21 BTW the HPFP has only 33k mi on it? Was replaced by previous owner at 51K by the dealer under warranty in 2015 Car has 84k now? WTH * Also after going through this it smells like like too much fuel and unburnt fuel in the garage

Have a read through this thread... https://www.e90post.com/forums/showthread.php?t=1149445 Also might be worth replacing LPFP sensor, LPFP looks like it's stuck, Last edited by Saif2018; 05-14-2022 at 07:05 PM.. |

Please look at the other parameters and see if you see something. I had the fuel smell in the garage a while back and it was the regulator or sending unit (Dr side). Replaced that 3 months ago and its been fine. So no more smell if its just sitting just nasty smell after starting it and its got full cats / stock exhaust. Please refer to my last post. Thanks

Someone can correct me but if I'm not mistaken, some smell from exhaust whilst cats warm up is normal. Last edited by Saif2018; 05-16-2022 at 02:40 AM.. |

WGDC after pid flatlining .. Please take a look
Happy Sunday everyone,
I'm still waiting to hear back from my tuner, however I'm having an issue . Didn't seem to have issues at the local track .. ran an 11.8 @ 122mph .. I know I know not fast. But I was on street tires, rwd, no boosting launches or anything dramatic, tools in the trunk and full interior so I was happy as this was a personal best for this car. https://datazap.me/u/turbohugh/e-85f...-30&zoom=48-83 My tuner first observed these strange WGDC spikes from these logs https://datazap.me/u/turbohugh/e85ff...0&data=3-23-29 Then I replaced the boost solenoids and this is the log. No spikes but flatlines. https://datazap.me/u/turbohugh/plug-...0&data=3-22-25 Tuner thinks I could have an issue with the wastegate either not functioning correctly or 'sticking' . The characteristics seems to have changed recently. Not sure where to start as I'm not getting any codes. I did have a #6 misfire recently, however I pulled the plug and it was gapped too short, so I opened it to what it was supposed to be .022 Now no misfires however I'm seeing strange throttle and wgdc behavior. I'm hesitate to revert to the previous revision, but as a teachable / learning moment I'd like to have more eyes on the logs so I can ask intelligent questions when I speak to my tuner. Hardware * 17ts [I know I know] * BMP Full PI with Motiv Reflex * B58 coils with +2 colder NGK gapped to .022 * Pumps and HPFP are all new. Awaiting my 'custom' fuel pressure regulator to hopefully stop the porpoising / oscillations of my LPFP. Thanks in advance for any input. All the Best, Oh, and feel free to look at any of the logs I try to keep notes and logs of all the mechanical changes. Hugh |

OK * Logging WGDC 1,2,base,pid * flashed the previous revision [1.5] * Logged to 6k Conditions were a bit wet so I didn't get a full log . This is really strange .. I think I may run a smoke test tomorrow if I cant find something obvious with the hardware. Thanks again for anyone taking a look at this . All the best, |

New Log After Custom Tune
Hello Guys,
Its been a while since i last posted my last log , Since then ive done many updrades the last was last friday had new upgraded turbos 17ts 11 blades installed along with replacing all 02 sensors,inlets,outlets,boost solionds,new valve cover,new coils , step 2 colder plugs. one thing i do notice is the spool sound is louder then when oem turbo is this expected? Here is a log the tuner had asked me to check some boxes to send logs so if its not what you need to view my logs properly let me know which parimerts to select, Current mods are FBO With Upgraded Turbos. Alot of maintenice parts have been replaced. https://datazap.me/u/carlos-lopez/lo...=1&data=3-6-18 Thank You ! |

-- basically I have sticking wastegates. If I drive the car easy, it seems to work fine, but heat these little babies up and the flapper is 'sticking' , fighting the actuator. ;Tl-Dr; * corrected a repair-induced error when I replaced [likely working] boost solenoids and misrouted the hoses. [the flat line logs] * correct vacuum lines and new boost solenoids returned 1 good log, and then spikey logs. My tech and my tuner agree this 'could' be sticking wastegates. Logs seem consistent with that idea. First run seemed almost ok , then the hotter the turbos got the worst the 'sticking' seemed to get. * Logs for the curious https://datazap.me/u/turbohugh/e85ff...og=0&data=3-20 I will be talking to my tech to install a set of vsrf catless downpipes [and that will be an opportunity to inspect the wastegates inside and remove the catted coBB downpipes.] A friend speculated my boost level + catted cobb downpipes might be creating backpressure. I don't know but I was gifted downpipes and I have to look at the actuators and wastegates anyway. I'm not really sure what to do. I may try some anti-seize or see if there's a bushing or something that's pressed in. The 17'ts may be finished. Thanks for all the help and sorry for the verbose responses. All the best, Hugh |

I changed out my LPFP over the weekend and flashed a new tune revision. Went for a drive and car seemed ok. I did a pull for a log and got a misfire cyl 6 under load at about 6000 rpm. I took the car out the next day after swapping #1 coil with #6. MHD showed a cyl 6 misfire but no CEL light on dash. I did not even feel it while driving...?? Drove car today and did this log. No codes stored. So not sure if was just related to the new LPFP swap and DME adjusting trims or if I have an issue with the tune revision.
Thanks for the help guys! https://datazap.me/u/jmadams/log-165...og=0&data=3-21 |

It was probably a shadow code from previous misfire, did you clear codes? |

I suppose anything is possible. Injectors were new in 2020 or 2021..new seals and decouplers. Everything was fine until I did LPFP and flashed V4 tune revision. I may flash V3 for now and see if issue persists. Waiting to hear back from Wedge.

DAW chinesium 17t's . I was gifted them about 3 years ago but have been running them for about 2 years. They were fine for a long time, but I've been abusing them a little the past year; no-prep drag racing at the track here in Crofton Md while running 21psi may be too much yeet for them . At this point I'm leaning more towards repairing the wastegate bushing if I can find a high quality bushing kit, or the DocRace V2 kit. Just keep throwing $$ at it I guess .

Any suggestions of which flapper kit ? So far seems like chinesium .. I'd like to find some high quality ones if possible. Also it seems TurboLabs has disconnected their phone# and recent reviews have been trending down ...

New build on custom base tune. Trying to hammer out big issues before I bug the tuner too much.
Pure600 FBO 93 Octane PC Coils Index 12 injectors I've been fighting a low pressure fuel system issue where the car would die when warm and wouldn't start back up again due to no low side pressure. I thought it was the EKP so I replaced it and so far haven't had the problem reoccur. I see in the log that between 5200-5300rpm the boost starts tapering off and trims start flying along with a big throttle closure. Not sure if that's a base map quirk or a bigger issue. Any opinions appreciated! https://datazap.me/u/adamlender/pure...og=0&data=3-20 |
