Motec V3.51 software strange AFR issue

[konstantinosIX]

Hello,
recently I upgrade my M800 from ver3.5 to ver3.51 and I am having the following strange issue on AFR!!!
When I am in idle with my laptop and Motec ECU manager ON I have 14.7 AFR mixture... when I turn the ECU manager OFF the AFR mixture change to 14.0-13.8 !!!!
Anyone using ver3.51 with the same issue?
I will try to upload a video before I downgrade it to ver 3.50
