I start new topic as I am working on tuning 1.8t 20v AUQ engine with hybrid K03s turbo with little bit tighter actuator fitted (obout 0.5bar).
I decided to compare AUQ file with BAM, as I think this hybrid turbo with new actuator is more similar to K04 from BAM than to stock K03s
But there is an first obstacle- I read on s4wiki about KFVPDKSD and KFVPDKSE. There is wrote:
The axes of these maps are nmot (engine speed) and vpssplg_w (requested pressure ratio) and the Z-values are pressure ratio across the throttle body. Look for the values in the table that start to exceed the threshold of PSPVDKUG (generally 0.95) and approach 1.0, and trace up to the vpssplg_w axis. The pressure ratio minus 1 bar at this column (when stock) should be your wastegate pressure (3-6psi for stock wastegates).
So I understood that in BAM file values of vpssplg_w should be higher than in AUQ file as actuator in BAM is tighter in AUQ. The reality is "a bit" different and in my files range of vpssplg_w values are 0.65-1.2 (for BAM file) and 0.95-1.5 (for AUQ).
Descritpion form s4wiki is quite accurate for AUQ file, but in BAM case it is difficult to understand for me...
Could someone give some hints?
EDIT: I attach screen with maps from both files
