ECU Richness adaptation values reset

[TonyMojzes]

Great day to everyone I have question, is it possible to reset richness adaptation values with DDT4all?
Why I need it?
I have Megane 3 2010 k4m with LPG. And the problem is that I'm always driving on LPG and after few thousand kilometers ecu started to adapt richness values to LPG, which are a bit different, because for example the fuel injection time on LPG is longer compare to fuel injection time on gasoline.
The problem is that when the car is cold it is running bad, rough, sometimes missfire a lot, sometimes engine die itself at idle.
I'm convinced that my problem is in ECU adaptation values.

Thanks for answer.
