Title: Can`t reach more then 1 bar boost on 2tfsi
Post by: melodic on June 04, 2013, 07:51:01 AM
I have audi a4 2tfsi 2007 b7. I`ve modified IOP and IRL, but the requested boost is only 1 bar. Where is the limiter?

These are limited because of the side mount intercoolers..

Compare values with say a stock Mk5 gti file, say around the area before LDR

actual boost is often 1,3 bar. But I want requested boost to be 1,3 bar.
LDRXN was also changed in my file.

LDPBN only limits desired load when there is an error in one of the many temp inputs

Huh...weird that they would change that.

When is it active in MED9?

All the time! 

It had be stumped at one point I can tell you...  US software usually has it set to 1 bar, European 1.25bar.  It's a true boost limiter, not pressure ratio or load.

Well that's convenient for guys like us, but really makes no sense in a torque based system.

Motronic is built around not caring what target boost pressure. Target boost pressure is determined to be whatever it takes to meet the torque request/specified load without sacrificing emissions and self preservation criteria.

Pressure ratio limitation makes perfect sense considering, but boost pressure?

Well, that was nice of them :D
