2018 hellcat question?

I have the MPVI2 and I use it for my 2016 hellcat and 2017 scatpack without any problems.But I'm going to buy A 2018 hellcat I keep reading about some kind of bypass? It wont just plug into the same port like the 16 and 17?

You plug into obd2 port but need to bypass the security module using our smart access cable.

thanks understood
