I have never looked into that part of it either. Email Justin if you can't find the answer on his website or the EFILive site.

 

I looked at both site and what i found was $125 for an additional license for the autocal, then whatever justin would charge to build a secon data log tune? I emailed justin to see on price. To me it looks like $125 for license (from efi live) and justin's charge to build a second tune for second truck any cost savings would possibly only be seen if you were looking to do a 6 speed truck (requiring autocal to do trans) and it might not be worth it with my dad's 4 speed (just do traditional data log tune instead). Just some info.

 

Good to know, thanks. You might want to start another thread with the specs of your dad's truck and ask if any of the guys can report their results of a tune on that setup. Might help you decide.

 

Justin from BB got back to me. Said its $275 for license and data log tune if you already have a autocal. Save a bit for the 4 speeds and a viable choice if a couple people wanna get an autocal together for the 6 speeds.
