Quick question for you guys. I have a 07 lmm and my dad just bought a 09, my question is will my tunes work on his truck? Is the operating system the same? Thanks guys

new updated website!
Don't go putting the 2007 OS in, with the 2009 TCM being different it might not play nice going backwards on the ECM. As the other poster suggested, the script should work fine as it's not OS dependent.

I no longer monitor the forum, please either post your question or create a support ticket.
My dad's 07 LMM has the 8594 OS.
I just tried to compare my tune to my buddy's... both of us have 2008 LMM's and the OS is different, so compare doesn't work. It looks like I have to change them to match, but I haven't read how to do it and which to OS to use for both... good thread for me to read!

It's my understanding that the 8594 OS is the newest OS for all LMM's
