There is a calculation gauge screen in new vemstune, and I see an interesting thing in pulsewidth calculation:
So lambda-target modifies the pulsewidth, I no need change VE table if I would like to go richer or leaner.
I think there was another method in older fw (I used 1.1.27) where lambda-target need for ego corr only.
Unfortunatelly I have not found the old calc method on vems site.
Is my inspection correct?
