My buddy has an 06 Kodiak with an LLY engine, but I had to select an LBZ controller, so can I just use the LBZ scripts to tune it??

Also it has no Tow/Haul button, just an O/D OFF switch, is there any way I can wire in a Tow/Haul switch? He really wants two different shift patterns. If i can wire in a tow/haul switch, can I just do a full reflash from say an 06 LLY pickup trans tune?

Here are the tune files
