That's Just The Nature Of The Beast...

I may have gotten this working correctly for 518AK SW 0003  Smiley

I reworked my own file now, for test. I just dont really understand the logic applied to ZDSU. It is a time constant, why would you change this? In Bissche's file it is set to 12, in the txt file it says sqrt/multiply by 2. Now that would yield a new value of around 3.5, since the original value is 3. The FR says it is 5. I left it at 3 in my file for now, since I dont expect this constant to work against the hack.

The sqrt(x)*2 thing does't make much sense...

I finally got the 5120 hack running on my 1.8 H-box after the 1013 divisions, did some testing yesterday and it was holding steady at 1.9bar (28PSI) @ my pressure gauge.

I was running into 50% opening blade issue @ wped=100. This really got me stuck for some time.
I have been reading this thread all over and I couldn't find anyone who may have got into the same problem.
Now BoobyTrap pointed me into the right direction for this.

There are 2 options for this to overcome, 1st easiest one is to set CWPLGU from 0 to 1 which will cause to pu_w to calculate plgru_w instead of plgruo_w to calculate plgru_w.
This is the same thing for plgrus_w.
The second option is to divide the tables and axis from map KFPLGUB and KFDPLGU as they use ps_w and pssol_w as input (which has been divided by 2 because of the 5120 hack). (Correct me if im wrong)

Anyway regards for BoobyTrap for pointing in the right direction for this cause.

I am now running with 0 281 002 316, 4 bar map sensor. I still need to do some calibration with the map sensor because I am not seeing same pressure in the logs as I see on my gauge and I can see my mixture is leaner than whats in my flash.

Running now with DSLGRAD 352 and DSLOFS 104 but I see somehow a difference of my new calculated DSLOFS 144,37.

I couldn't make a good log yesterday because of the rainy weather which caused lots wheelspin.

Going to get myself the RS6 recirc valve and make it circulate back to intake again and get my MAF working again, but that's still a work in progress.

Will update soon with logs.

A few other possible map changes on ME7.1 (2.7t)

DIFFMAX (pus_w) - probably should divide by 2, but stock probably won't hurt - just makes diag less sensitive
PUSMAX (pus_w) - We're allowing double pressure, so leave alone
PUSMIN (pus_w) - probably should divide by 2, stock is 450, and 900 is likely not so good at altitude? Again, this probably just makes diag less sensitive than stock
PSAPES (used instead of pus_w when CWPKAPP bit 0 is set to 1) - leave alone unless you need CWPKAPP for something
NDLDIAPU axis (pu) -probably should divide by 2, stock is 600/1000, and 1200/2000 is likely wrong - only two output RPM values (2600 for high altitude and 2160 for low) so maybe it doesn't matter; if we leave it alone we'll always see 2600. Either way, for big turbos, the RPM needs to be shifted up anyway.
DPVDKDWG (pvdks_w - pu_w) - ?

listed but not in my mappack?

HSLDSUA (pu_w)

PUSMIN
must be changed necessarily.
had the problem because a friend lives a little higher. Car run very bad
