Look here pal.
We're not here to shit on your parade.
We are willing to help, but since you won't or can't
supply us with the information or data we need to help you.
Then we can't help you.
We are in no way obligated to help you, we do it out of free will
and use our own free time to do so.
And "yelling" at people because the won't help you,
because they can't with the little data they have
isn't constructive or will help further your cause in any way.

I do not expect anything. I ask for help, do not yell at anyone. But if I feel offended I answer as well. You were not obliged to help me, I never did. Thank you anyway for your help and apologize for the lost your time.

Let's get back on topic, since you ignored the single most important piece of advice here: You can log more than one variable at a time.
Lose the MBC, lose the blow-off, learn ME7 properly and you'll have a great time.
1.5 bar with 0.9 lambda?! You're hitting EGT and that's why it's dumping.
All of the above. |

My personal experience would advise you to lower boost, and add timing instead. And get your fuel sorted before you begin to boost the living hell out of it. Also if you are basing your EGT on internal EGT model, then it will be off if you are using a TFSI turbo. If you have a EGT sensor, See what modeled temperatures are in downpipe or before cat instead of manifold, and make LAMBTS use that temperature. |

i have franken turbo f23 kit . if i remove MBC and connect n75 my boost joke, i have picco 3bar ore more turbo pressure, KFLDIMX and KFLDRL are original . i try to decrease the KFLDRL but same result , big picco boost. cant handle the KFLDRL. and i thought for mbc solution ,now have 1.3bar boost. 880 grad egr . 10,5 plx afr .
i go up with pressure , max i try is 1.5bar, i ajust timing , LAMFA and KFLBTS. plx afr is 11.2 but nothing HP more that 243.
car have beautiful torque 410nm , 243hp but after 4700 rpm all finished .

Its about the way you tune.
You are a commercial tuner and dont even know how to log?
Do it again with WOT in the whole range and remove the mbc like adam recommended.
take your time and do it the right way.

And you didn't bother to log to figure out why? If you can't get anything working without an MBC, why bother tuning at all? |

Stock DIMX and DRL will never work with that turbo. And ME7 doesn't like when you remove the N75 from the boost control loop. I suggest you take a look at the LDRPID tool that was created not long ago, that would definitely help you control the boost with the N75. But you will need to be able to log with me7logger. |

Hell, just use RAPP to calibrate it to get you in the ballpark for an estimated DC and properly controlled fuelling.

Why did you just post a bmp enclosed in a rar? Post a log or nobody is going to be able to help you.

LDRPID has many setting. But it is a clusterfuck. Read the boost PID section on s4wiki, that'll get you started. |
