Anyone tried using the 3840 on a 2013? Most places I've looked it says it works on up to 2012. That kinda sucks as I have a 3840 I used on my 2006 Hemi that would be great if it would work on my 2013 Cummins. I'm thinking they must have changed the programming quite a bit as that is when they added the DEF and such. Think I already know the answer, just hoping I could get away from having to sell this one and buy a new one.
