Problem solved, I recalculated flux linkage, the formula I used the first time was wrong.
I found a post where Benjamin Vedder gives
Flux linkage =60 / (sqrt(3) * poles * pi * kv)=60/(sqrt(3)16pi*130)=5.3mWb
Gain=1000 / (lambda^2) where lambda is flux linkage = 1000/5.3^2=35.6%
These calculated values are really close to your values Alexandre.
Straight away no more cogging and ABS. Increasing stator compensation to 15% also made a difference at high current.
