Help putting wheel size back to normal lightblue app

[Drtcmm]

Hi, I changed my kenevo 2018 wheel size to 800mm and I love it. The only thing is the distance on the maps in Mission control show wrong. I am about to get the specialized computer for the bars so I need the wheel size to be right for the speedo. How do i do this with lightblue? I was thinking of modding it with blevo instead. Thanks
