Golf 6 1.6 mpi lpg - Installation Landi Renzo evo obd

Hello, first of all I would like to apologize for the probably intuitive German, but everything goes via google translate. I found this forum via Google where people know quite a bit about LPG and cars - golf in particular. I have a Golf 6 1.6mpi 2009 without LPG and I want to add a Landi Renzo LPG system. Where I read the model of LR would be evo obd but I found something related to omega? My curiosity that I couldn't find is related to obd linking to CECM and Ross Harvey vcds enabling. Can I activate this system via vcds? Which components do I need? Which activations should I find? Which Landi Renzo model should I be looking for, to install it in the car? Is evo obd good? Has this ever been discussed in the forum? If so, can someone leave me a link here? Thank you and I look forward to your help!
