Kodiak 06 LLY tuning

[LS1FREEK]

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

All 06 to 07.5 trucks use the same ECM. They just have different calibrations in them. That's why GM calls them an LLY. Anything you have from an LBZ will work on that ECM.

As far as the TCM, I can't really help you there. I believe the TCMs are physically and internally the same, but they run different programming. Since there is no way to full flash a 6 speed TCM, you may have to swap the TCM in order to get the truck out of T/H mode. I can't look at the tunes right now, but if the normal shift tables are the same as the tow/haul tables, you may be able to wire in a switch and adjust one table or the other. From what I understand, those TCMs always operate in T/H mode.

Yeah, that's my understanding as well, its always in T/H mode. If anyone else has any other input on the trans, lemme know. Thanks!

Hmm, I'll look at the ones I have tuned. I have done several and its never been an issue before. Why is tow/haul so important on a truck like that?

It would be awesome if there was just a looped wire from one pin to another on the TCM, but im sure that isn't the case. A new OS is probably in order to fix that, but as you you know EFILive doesn't support Allison TCM full flashing.

The TCM is locked in T/H mode to keep the converter from getting fried, because they are Medium Duty truck meant to haul stuff. And there has been somewhat of a demand by the "little men" of the world who feel they need to daily drive them and would like to have T/H mode disabled so the fuel economy isn't in the shitter all the time.

LOL I am very familiar with them, there are alot of them around here. I dont know anyone daily driving one but I'll have to check what kind of mileage they are getting empty if any of the guys know that I tuned. They get crappy fuel mileage mainly due to the 4:88 gears IMO. I run the same 245/70/19.5 tires but have 3:73's but turn about 1,000 less rpm going down the highway going off memory. They are great for what they were made for, towing. All the ones I tuned picked up mileage but I dont know how much. Most of of the guys I tuned them for arent worried about mileage.

Thats pretty much the deal there.

There are a few that i see quite frequently here in the Portland, OR metro area. I know 2 for absolute sure cuz i know the guys. And yes they are on the small side. One guy uses his for "work" but his wife has a car and thats it, 2 vehicle family and i see the whole family loaded up in the "manhood extender" all the time around town.
