I'm tuning my car at the moment. The setup is the following:
1. 2.0 TFSI (220 hp version)
2. Turbosystems IS38 ball bearing Hybrid (Stage 1)
3. HPFP and LPFP upgraded
4. Wagner Intercooler
5. Panel filter and pipes upgraded
6. TVS Engineering Stage 3+ DQ250 gearbox tune
7. VehiCAL to log

The problem is the slow boost up. I have collected the logs from exact same setup of my friend with the Revo Stage 3 tune and his boost up is much stronger than mine. I don't understand why is that, as in the relevant RPM range my wastegate is completely shut, so there is no way to increase spool up using it. Attaching the logs for the both cases (event marked in GREEN):
Revo Stage 3 (logged using VCDS): https://docs.google.com/spreadsheets/d/1wi2l02EUnIWFHQHumEUfKZIhnxjtprGSgrIufHgX0hc/edit?usp=sharing
My custom tune (logged using VehiCAL): https://docs.google.com/spreadsheets/d/1QPFryVPDPpc36McA8m-JyT6w7_NfMwUG505icFEPyeE/edit?usp=sharing

P.S. I see quite aggressive negative ignition angles in the Revo tune, however, during the duration of negative angles event there is no significant difference in the boost. The difference comes later and carries on.

Should I log lv_lamb_scav_act?

Anyone knows about ip_mfl_int_scav_inh_thd table (Air mass flow integral threshold for scavenging inhibition)? My FR about SIMOS18 have no information about it whatsoever. It has coolant temperature and pressure (most probably up throttle) axes and grams as Z-axis (all zeros in my case).

Thanks. Another one: is ip_cam_sp_vcp[0][0][0] (Intake, STD Lift) this map contain advance angles, or is it "reversed" advanced angle? If I see "minus" sign in front of the number in that table, does it mean "advance" or "retard"?

1. It's a DI car only, no injectors. Not relevant.
2. WG is closed, precontrol factors are logged
3. It is not lean run (lambda 0.83, DTM_PAS mode combustion mode)
4. Ignition advanced till knocking start occurring and rolled back 3 degrees everywhere in the map.
5. I'm already using VehiCAL for all the logging.
6. I don't want to risk my motor: I have high pressure oil pump stage activated everywhere.

So, no hit there. It's definetely cams tuning required, that's why I'm asking the question above about Camshaft position setpoint maps and Z-axis of it specifically.

Solved. Was scavenging and VVTI position. Boosting up 550 hp turbo in 500 RPM.

Yes, you were of a great help for this note. This is what pushed me into that direction. Thank you.

Everything needed is in the thread.
If you don't know what valve timing or scavenging is and how to adjust this, then time to start reading.

Nothing to do with ECU, purely engine/tuning knowledge of basic and DI systems. Scavenging on DI is overlap without blowing fuel out the exhaust, nothing more.
As to how this is beneficial for spool, really helps if you read some books on the subject or at least understand how an ICE works instead of playing Excel spreadsheet all day!
