So it seems I may have an issue from what people have said, and I am posting a seperate thread in hopes for quicker assistance so I can get my car fixed sooner. Here are my mhd stage 2+ logs on ACN91, with XHP. Car had all injectors, hpfp, lpfp, fpr and lpf sensor replaced within 10,000 miles. Thank you, car had 75k miles

What sort of issues are you having?

I see one major problem and potentially one minor.

- It's a little slow to build boost but it does reach target and doesn't max out WGDC so I wouldn't be overly concerned unless you have a known boost leak.

- You have a LOT of timing corrections. This is more concerning and needs to be addressed.

What plugs are you running? Are your injectors NEW genuine index 12 from BMW? What coils? The fact that it's across all cylinders more likely points to inadequate octane but plugs and injectors/coils could contribute too.

Have you ever been walnut blasted?

in the app, what is the ''last safety code'' ?

seems a bit lean and it tries to correct it. at the begining of a pull you're around 16-17 afr.

i'm around 13 and slowly get around 11.9 at the end of my pull, trim 20 all the run. your trims are 50, so maxed out !

you run 91 oct ? meth ?

always a good idea to check for a boost leak, there's many point of leak on those n54s

What is a safety code? I will get shadow codes 2AAF, and sometimes 2FCA and 2FDA but I haven't had those two. I'm running 91 ACN, no meth or anything just pump gas. And I'll check for a leak

I don't notice any issues, but more
so I wanted to make sure everything is as close to perfect as it can be. The plugs are 6x Bosch ZGR6STE2, and coils are 6x Delphi GN10328s, all from rock auto. The Injectors are all genuine ordered from UroTuning. I have not ever done a walnut blast yet. I wasn't ever aware of a boost leak, but I do have new vacuum lines and boost solenoids coming in. Thank you so much for the response!

Here are 2 more logs, dsc off 2000-6500 in 3rd

Ok, logs seem's to be near to be ok but:

- You have correction on 5/6 cylinders, that's not good, try to add E, check your sparks/coils or reduce boost
- Your boost is pretty good but i found it to be a little bit too low @ high rpm for V10 stage 2+.....When you look at your load actual you reach "only" a target of 165 at 6000rpm, wich is near the level of a V9 stage 1+, V10 stage 1+ reach 170 on V10 on my car. V7 2+ wich is less agressive reach 168 @ 6000rpm.
I'm ok that 170 or 165 load does'nt make a difference in real world.In every case at this rpm, whp will be approximatively the same, the most important things is WGDC.You can see trough your WGDC that your turbo have to works too hard to reach load target, 80% @6000rpm (85%@6500rpm) is too high especially when regarding that your IAT are pretty low (around 80°F).you are at the limits of what your turbos are capable of providing


Your tubo are tired or you have a small boost leak somewhere.

You turbo lag is a little bit too high too, you reach boost target @3200 rpm and only 5psi @2500 when i reach already 9/10 psi at this rpm. A good turbo lag is around 500rpm

PErsonnaly i found this tune too agressive for your setup, you will destroy you turbos quickly running such high
WGDC.

Make a boost leak check and run a less agressive map like V7 1+ in the meantime.

If this boost leak test allow you to found a leak then you will can retry this v10 stage 2+, if not, that's your turbo wich are a little tired and i will advice you to run a less agressive map by waiting to change them.

wow, when I checked your log on my home pc the link directed me on a total different log, it was a jb4 log, now on my job PC I see a mhd log ! wtf ??

my browser or you changed the link ?

In that case simply forget what I wrote

SOO, I found a lose vband on my fmic, and tightened it, and then added a gallon of e to my tank, and took 2 new logs, what do u think?

[vadonchez]

timing corrections are gone that's good news but it's worst on load actual vs target side....
I don't know what you did exactly but check your work again, now your load actual is only 150 at 6000rpm wich is less than the load reach with only a stage 1....
