No. You just use a valve that is big enough, and these issues do not happen.

It's really the basics. You can disagree all you want, fact is that you need a stronger spring to keep it shut on idle or suck in unfiltered air.
Stronger spring - does not open soon enough when it should be.

Less efficiency, harder on the turbo, and makes MAF readings go all over the place. You should have the N249 actuating your BOV, instead of removing it.

I'll hook the N249 up for a test just for you ;-)

Any Updates on this for M-Box?

I'm planning on posting a stock M Box modified and the xdf tonight.

splendid!

I am already sick of tuning my car on fixed KFLDRL... Do I put high enough PID limiter to boost up quick and overshoot or keep it low but have "slow spooling" turbos... a conundrum. Having full PSI range in logs will rock too!

I hear ya there... I was testing the PID control the last few days to make sure it was working right before I posted everything. It seems to be.

Woohoo can't wait to tinker with my file tonight. Reading through all this again if I leave DSLGRAD and DSLOFS at their regular values and still run a 2.5 bar map sensor until I get a new sensor my logged boost should be half of what it actually is correct?

Any chance I can purchase one of those MPX pressure sensors from you ?

You have to rescale them

To run the stock 2.5 bar sensor you divide DSLGRAD and DSLOFS by 2.
When I upload files later I'll have an M Box file for the stock 2.5 bar sensor and one for 4 bar sensor.

OK so I took a seconds to convert some M box files over to 5120 support.
Versions should be self explanatory.
XDF files included with all the changes.

This may not be complete, but it works and has been used on my daily driver for over 500 miles now without any problems.

These are based on the 8D0907551M-002 file:

ME7Check v1.12 (c) mki, 06/2004-05/2012
Checking file 8D0907551M-002.bin (size=1048576)
Reading Version Strings...
-> Bootrom Version = embedded in CPU, asume 05.12/05.32
-> EPK = 40/1/ME7.1/5/6005.01//22m/DstC2o/011200//
-> Contents of ECUID data table:
   - '0261207143'         (SSECUHN)
   - '1037360857'         (SSECUSN)
   - '8D0907551M  '       (VAG part number)
   - '0002'               (VAG sw number)
   - '2.7l V6/5VT     '   (engine id)
-> Contents of ECUID data table:
   - 'HW_MAN004'

-> No errors found. File is OK.   *********************

[Editor's note: There are a few minor errors in these files... please read http://nefariousmotorsports.com/forum/index.php?topic=3027.msg63024#msg63024]

Here's the "nyet" hpa list updated for the 8D0907551M box also for those that might need it.

If you want I can just convert your latest file over to 5120... or just use the xdf...

Note:

Logged pressure variables will now be half of their actual value using normal ecu logging.
The easy fix for this is to double the scale factor being used.
For ME7Logger this means the values in the .ecu file.
For example ps_w scale factor gets doubled to 0.078125

Great work. You went this far, post the .ecu file with the corrections as well.

LOL.

Wait for it. Someone's going to come in and ask for more. It's inevitable.
