06 gmc truck os swap?

[vortecyota]

I have a friend who is tuning a 2006 gmc 6.0 truck. The truck was originally equipped with a 4L65E and I installed a FLT level 5 4L80E. I repinned the case connector and built an ISS harness.

The tuner is having trouble finding a matching OS(12606807) that includes a 4L80E segment, to use for a segment swap. As far as I know he can choose any 6.0L/ 4L80e OS and load it into the PCM. However, he is thinking that that PCM will only accept OS 12606807.

Is there something about the late PCMs that will not allow a complete OS swap, or does it just have to be one of only a few compatable Os?

Thanks in advance!

Hi vortecyota :)

can you post his .tun file here...?

[vortecyota]

Thought I'd find you here Joecar. To answer your question... no, he is using the OTHER software. I can pull the tune file with my laptop and post it, but it would be 2 days before I could get back on the forum with it.

Unfortunately, he does not have that much time, I think hes a little behind schedule as it is. He is considering making the swap to the GOOD tuning software, so if he wants to, I will take my laptop to him tomorrow after work so he can test drive EFILive.

Sorry I can't deliver the goods today, but if he hasen't nailed it down by tomorrow I will go to his shop and load the file and post it Thursday. Thanks again!

He should be able to use any 1MB LS1 PCM OS (will be a truck OS as I dont think any cars came with the 80E). So if you can find a 80E trans file and a compatible OS, you'll be good to go. Doesnt have to be a 6.0L OS, probably would be either a 6L or 8.1L but you can change either to suit his application.

Just saw your last post, yes if he's using the other guys, they only do seg swaps if you email support and apparently it takes a few days or a week to get done. Post it up if you can!

[vortecyota]

Hmmmm.... I don't know anything about the "OTHER" software, but I wonder if it does not give the tuner the capability to upgrade the os?

Im not entirely sure, havent played with it before. I think it will charge you another set of credits to do an OS swap though...:bad:

That's what I am running into at the moment. I am unable to find a OS with a 4L80 in it that matches the OS in the vehicle.

Now it looks like to me you guys with EFI can do the segment swap yourself, were I have to send in the info to support for them to do it.

[joecar]

It is possible to run the 4L80E from the 4L60E OS...

For each of the 4L80E and 4L60E:
Look carefully at the connector pinouts,
Look carefully at the solenoid columns in the shift chart,

You will see:
- you have to use a relay to invert the 2-3 Shift Solenoid signal,
- use the 4L60E TCC Enable signal to drive the 4L80E TCC PWM signal (i.e. discard the 4L60E TCC PWM signal wire).

This is what slow67 has done... but do look at the reference material and logic this out.

Thank you Joecar! Thats vortecyota's job if we have to go this route:doh2:

I'm going to dig alittle more and see if I can find anything.

What I am saying is lets throw the Os thats in the truck now out the door and upgrade the entire OS to one that we can find a 6.0/ETC and a 4l80e cal for. I'll come by tomorrow and let you use my software.

Oh, yeah... welcome to the dark side:welcome:

[ScarabEpic22]

Just looked at a few files on HoldenCrazy.com, didnt see a ETC OS with an 80E, I thought I might get lucky with the 8.1L OS, but they use the Allison 1000 trans.

Might have to do the 80E using a 60E OS for now.

[vortecyota]

Please don't tell me that! If I have to do some more wiring mods it will have to be free because I think I already earned all the money he had. Plus Aric needs that truck done and gone and I am in the middle of a '98 Vortec 5.7 injection swap in an '86 K1500 at home. So I really don't need to pull off of it until I'm done.

[joecar]

The C/K truck platforms had the 4L80E as an option (it shows up in my 2005 Service Manual DVD)...

someone somewhere must have 1MB LS1B 4L80E file.

[vortecyota]

Thank you both for the help so far. I'm going home for the night, but Aric may be back on. I'll bring my laptop to work tomorrow in case we can come up with a solution so I can go to Injected Engineering after work.

Thanks again!

Hows this Joe?

LS1B 1 MB 6.0/4L80E and ETC.

Note: this is not a bone stock tune, just the only one I have available on this computer right now that may be helpful.

[joecar]

That's a 1MB 4L80E 12613248 file with Flex-Fuel and ETC. Edit: I looked closer at that file and I saw FF set to No.

The 1MB 4L60E 12606807 file on www.holdencraqzy.com (http://www.holdencraqzy.com/) also has FF and ETC.

One would think those OS's are compatible, but I don't want to make an assumption, let me ask someone...

:)

[vortecyota]

Do you mean that Aric may be able to use an OS for a flex fueled engine and just calibrate the engine segment (which he still has to do anyways, turbo setup)?

[vortecyota]

I have a friend about 2 miles down the road who has a stock 07 2500hd 6.0 ETC 4L80E, and he says its not a Flex-Fuel. Can I just go down there and pull his .tun file and give it to Aric, or does doing an entire OS upgrade involve more than that? In case we don't get super lucky and have the same OS as the truck Aric is working on.

Thanks
Brint

[GMPX]

I think the attached files will do the job for you.
1Mb PCM
4L80E
Non Flex Fuel
ETC
6.0L

The 2006 Hummer 12613246 OS is the closest to the one you already have, in fact it was an update to the one you have, so I'd suggest full flashing that in.

Cheers,
Ross

[vortecyota]

Thank you very much GMPX, and all! Aric will soon be a proud new owner of EFILive. Will post results tomorrow, not that you or I have any doubts.

[vortecyota]

I left my software paperwork at home and I need to buy a PCM liscence today. Is there anywhere I can look in the tune tool to get my serial and authorization #s?

Hope I didn't screw up!:doh2:

[joecar]

Brint, go Help->FlashScan V1/2 PCM/VIN Licensing... you should see serial number and authorization number(s).

Let us know how it goes.

[Big Mike]

The tune I posted wasn't setup for flex fuel. It's from an '07 Silverado 2500HD classic also. You can see in B3101 it's factory set to "no". That part I didn't change. :)

[vortecyota]

I'm at Injected and downloaded the .tun file for the Hummer and it is a 4L60E. I guess I'll try the van file.

[ScarabEpic22]

Ross, the files you posted have very similar OSs, but not exact (Van is 48, H2 is 46) so you cant do a seg swap from the Van to the H2. But the Van file looks to be the best fit!

vortectoya, Id full flash the Van file in and see if you cant make it run.

For Paul/Ross, what COS would you use with that 07 Express Van OS? Doesnt look like there are any COSs for LS1 PCMs past the 05 MY. Also, just FYI all the COSs that end in 5 (and appear to be the TPS-VE COS) are still labeled development versions in their description.

[joecar]

vortecyota/Brint,

Did you get the PCM license sent to you ok...?
