Why would you deactivate a safety feature telling you that you screwed up your tune? |

1) Have your requested boost line up properly with your actual boost.
2) Don't use an MBC
3) If you have a wastegate tighter than stock, tweak the first line of KFDLULS (or KLDLUL) to match (or exceed) your wastegate pressure.
The stock values of KFDLULS (2000mBar!) should be more than sufficient, although KLDLUL (only ~500mBar) is on the edge and could use tweaking, especially if you are running tight waste gates. This applies even if running conventional N75 boost control!
that said, if you spend a lot of time WOT with a very negative lde you are doing it wrong.

so if i now increase on this file LDRXN from 210 to 230 the problem comes back where the boost is cutting off to 0 Bar

Get a proper log. Not VCDS.
One more time:
If you spend a lot of time with a very negative lde you are doing it wrong.

FORGET ABOUT KLDLUL for a moment. Make sure your actual boost tracks requested first. For the THIRD time: If you spend a lot of time with a very negative lde you are doing it wrong.If you get boost figured out WOT, THEN worry about KLDLUL (when req boost is 0) and wg cracking pressure. |

Also another way to go about this without KFDLULS would be KFLDRX0 delta filling in overboost. Reducing KFLDRX0 and raising your LDORXN would reduce the magnitude of the setback when you trigger overboost. I believe setting delta filling to zeroes and raising max load during overboost to say 191 would effectively cut out the intervention completely.
I know this is a very old post, but I just wanted to comment: on some files, you'll set a code, and the car will stay in limp mode until the code is cleared, so fiddling with KFLDRX0 and/or LDORXN isn't actually a great fix  |

I've wondered this for a while now..... In the area of spool up, if you lower requested to somewhat match actual turbo spool, will you leave any power on the table?

Depends entirely on your wastegate setup, but in general, you want to set things up so you have 100% dc during spool. If your req boost is too close to actual the P and I contributions may not be big enough to result in 100% dc. Now, if your waste gate is tight enough, that might not matter. |
