hi guys , im working on a golf 2.5 usa me7.1.1 and having some trouble with requested lambda.

there is not much info about this ecu but i found multiple maps in 2d. LAMFA etc.
I tuned a few of this engines but they just repsonse on what im asking for.
the ori lambda request is 0.8958 , i checked it but in the logs the request lambda still at 1.000.

if someone can give me some hints to look for

ori + mod(verry basic) + log(mod) attached

Thnks
