Been going back and forth with my tuner and since I'm new to modifying and tuning cars I wanted to get a different pov of some other guys who know what to look at when looking at logs

Help with N55 log - target boost
Hi,
I want to improve my performance but before I start, I have a 28A0 code that I am trying to troubleshoot. The car is a bit rough at idle sometimes but seems to drive well enough. I have logged it using MHD to try to find out what’s happening. The main thing that’s odd is on WOT, my target boost stays at around 8 PSI and actual boost hits 16 and then declines. It would be great if someone take a look and see if they can suggest what’s happening. What does target boost max out and actual follow a more usual pattern? https://datazap.me/u/dp335i/n55-stic...3-4-15&mark=29 |

First Logs - Healthy?
Did my first logs. Stock 1M.
Looking for help interpreting results. Car pulls really well in stage 0 and stage 1. My butt doesn't detect any issues. But the logs look like there is consistent cyl timing corrections. Pulls are in 3rd gear from 2000 rpm. Am I safe? Log1 MHD Stage 0 https://datazap.me/u/mahlzeit/log-16...-9-10-11-21-25 Log2 MHD Stage 1 91 Oct https://datazap.me/u/mahlzeit/log-16...-9-10-11-21-25 Thanks in advance! |

Corrections are probably due to the 91oct fuel. You could try 93oct fuel or add E85 to confirm. Have you done your plugs/coils? |

Ok, will log again from 2500 vs 2000. I'm in CA, so 91 is the best I can normally get. I have not done plugs/coils yet, but plan to next week at my next service. Is there anything I should concerned about? Is it safe to run Stage 1 or Stage 0 in this state? Thanks again! |

I'm back to sorting out my N54 swapped wagon. FBO , relocated inlets, I was driving it without the JB4 because I was having some issues the logging with protools but it turns out that my Cas is still reporting the 328 vin so it doesn't default to 335 logging items.
I put the JB4 back on so it can at least give some feedback through there. I did pulls on map 2 and map 5 and I'm scratching my head why it never requests more than 10 psi? Should be like 15? Seems lean too. Anyone here good with the JB4? I have an account for N54tech but no idea what my login is there. https://datazap.me/u/n54wagen/jb4map...log=0&data=1-4 https://datazap.me/u/n54wagen/jb4-ma...log=0&data=1-4 |

Yes it's safe to run Stage 1, apart from the timing corrections looks fine. Good idea to do the plugs and coils though. Worn out plugs/coils can also cause corrections. |

Not to stray too off topic but found my "mysterious" cyl 6 misfire. All of my plugs were finger tight.! I installed new NGK Iridium plugs and torqued to 23nm. They have a large crush washer so the only thing I can think is that I hit the torque spec as I tightened and crushed the washers but they were actually not completely torqued. I guess a good rule of thumb is to drive a few days and then re-torque plugs!

Hello everyone, I was wondering if anyone can take a look at my friends log. It's a 2009 135i FBO stage 2+ on an e50 tune, upgraded inlets and outlets as well as an upgraded LPFP. Here is the log

lol, post a log once you've done the plugs and coils. You will probably still get some corrections but they should be significantly less, hopefully.

I'm guessing DME is closing throttle as a result of which boost is dropping due to load actual taking a nose dive from 5k, no idea why it's dropping so much. You'll have to send the log off to your tuner and ask your tuner. Last edited by Saif2018; 05-21-2022 at 07:50 PM.. |

Hey guys new to data logging. Boost, not hitting boost target. Getting a 2f6c 30ff code with half ce at around 5/6k rpm. This log shows that.
I saw cyl 1,3,5 timing cor? Dip just prior to when I assumed the ce light came on. Any help appreciated. https://datazap.me/u/habookedeem/log...38;data=3-4-20 |

Thanks. Waiting on Ken, seems like business is booming for him... Hoping it's just his base map, but we'll see. I cant afford any more surprises with this car!

Chasing a gremlin now.. Lol.
Not sure what's happened. Changed lpfp and coils. Thought ngk plugs looked good. Per my tuner I used protool and reset engine adaptations. Flashed and drove car for 30 minutes before log. Had cyl 6 misfire again at 6200 or so and super knock cyl 1 and 5. I have a known good set of NGK 2 step colder plugs I plan to install to see if that cures the misfire... Update... Swapped in the ngk 2 step plugs and car runs fine now. Always felt like it ran better on these plugs. Adaptations and fuel trims are beginning to get better better too. https://datazap.me/u/jmadams/log-165...?log=0&data=21 Last edited by jadams161; 05-29-2022 at 06:20 PM.. |

I don't know why its not compatible. maybe the ame only does one but not both thermistors. ptc versus ntc. I just took it at face value and bought a new one for 20 bucks.
yes, its nice to have a tuning area. |
