While this correlates well with my fully defined G-box, the pssol_w axis values look odd... they are 1.1719-9.3750..

that can't be pssol....

It's definitely pssol_w. The table isn't used however, similar to the lamfa axis.

I should clarify, the map is used, but it does nothing as it is all 1's.

For the sake or completeness, there is also KFWPLGTA which gives plgta and is also filled with 1's.

KFWPLGTA 0x19749 * 0.0078125

Rows:
nmot_w SNM08LDUW 0x12AB6 * 0.25

Cols:
tans STA08LDUB 0x1010C * 0.75 - 48

The output from KFVPLGU is multiplied by plgta and the result is then multiplied by pu_w giving plgrus_w.

Therefore, plgrus_w is always equal to pu_w.

I'm late to the party per usual, but this thread is a big help. I never even realized until recently that the allroad boost was controlled this way. Thanks to everyone!

I have problem defining rpm axis for KFVPLGU.
Would any of you take a look, what is the RPM adress, please??

I had found KFVPLGU on F-box @0x15946 but can not find on k-box...
