I think he's saying if you are going to have req boost ride the 2550 limit, you'll need to get HBN out of the way, and using HBN as a safety feature to limit boost (through limiting req load) is pointless.

He's right on both accounts, imo

A better question is: why on earth would you want to ride the 2550 limit?

Thank you, probably better worded than the way I had it but prj's arrogance (entitled or not) was starting to drain.

The 2550mbar limit is a soft limit on the K04 cars. They have 3bar MAPs so you can hijack the PID to drive it above 2550mbar.

Just dropping in a 3 bar MAP does no such thing Tongue

It's not dropped in - its standard. K03 based TFSIs are 2.5bar sensors, K04s 3bar. So will measure / see pressure above the requested limit.

The 2550mBar limit is generally in the ME7.x context, where it is hard limit in the ECU.

What is the ps_w scaling on the ECU you are talking about?

You are wrong. Again, it does not limit boost, it limits load, and ME7/MED9 cuts throttle when rl exceeds rlsol. Boost is completely irrelevant.
Does not matter if you ride req 2550 or not. Whatever hacks you are using (even if 2550mbar = 3000mbar or whatever), you can still use KFLDHBN to limit load to sane values at high IAT. Look up ldrlts in the FR.
There is never any point to max this map apart in piss poor tuning.

Soft limit?
ps_w scaling is max. 2550mbar. plsol scaling is max. 2550mbar. Nothing soft here, it only displays the sensor value and does not do anything with it.

There is no arrogance here, the only thing this thread reeks of are ignorant people talking shit about things they do not understand.
Go on then...

I had a BSR stage 1 map on my old S60 2.0t. KFLDHBN maxed across the board...

Then again, it also had a random 0 value at high RPM in KFLDRX.... Funny.
