Another route is using a medium duty application allison controller but with that route, you don't get the tow/haul or the tap a shift functions and I don't believe you can use efi live with the allison system. I still have some time before I have to make that decision, hoping stuff for the 6 speeds gets a little more refined when I get to that point. Its amazing how fast things add up though huh? When I started my project I figured ten grand would come close to puttin it together, boy was I wrong. When I first started, I just wanted to throw the motor in the truck with a 4l80e trans I had kicking around and drive it but its hard to tear something that far apart and not do a nice job putting it back together. I dont want a show truck for sure but I want it to look nice and be reliable. Its a case of "while I'm at it"....

I have an allison PCM and a partial harness I thought about using. Just unsure as of yet. Mine is only a 5 speed as well. I just don't like the idea of building a truck, using the a1000, and then hating it because I can't tune it without a trip to allison 20 times until it's right. Or, spend $1800 for Scott's controller. Too much money.
