Well, i plan to buy one for my 3.2V6 156's, and use it as well on my 20VT......having in mind that i had also one Locost with 20VT on it, it will be good idea to have it.....my intention if i buy it is to wire it up to all of my rides and change it between when doing trackdays. Saw that you're from Poland, and it's made in your country. Emailed the company, but they said that no base map for Alfa V6 engines, did you have any for 20VT? Are you happy with it?
