Lambda very lean at WOT!

Post by R-12914 »

Hi Hondata,

since a few days abruptly without having made changes anything, my WOT Lambda is only very lean at 0.85-0.86.
Before it was on 0.80-0.81.

I have send you Logs and Maps via Email.

What is the problem or could be the problem?

Thank you!

BTW: Maps & Datalogs i have send you via E-Mail

I don't really see a drastic difference in them. Where exactly in these are you seeing an issue?

Please look on the "2.35_18-11-2019" Datalog on 14:12 minutes for example.
