Hi im working on a 2012 cummins for my buddy while im up here in Canada hunting. that's where he is from and lives. He asked me if I could remove the emissions on his truck and shut it off with efi live. I thought I could but it don't give me that option. Since he is in Canada and don't have to worry about the emssions and help on what I can do so the CEL don't come and stay on would be awesome. Thanks.
