How do you do a segment swap?

[Redline Motorsports]

How do you mix a 99+ F body OS with a 4L80E trans calibration? I haven't been able to confirm if the 60 and 80 have simliar parameters.

Once again Howard, good question. I would like some insight as well.

[dc_justin]

You'll need to have an 80e calibration that uses the same OS as your 60e calibration.

Open the 60e calibration as your primary file, then load the 80e calibration as your alternate for comparison.

Go to the edit menu and "Copy Entire Segment". I would assume that you would need to copy both the trans calibration and the trans diagnostics.

[Rhino79]

Correct!! I just did some segment swaps this past weekend, saved an assload of time!

[joecar]

I'm going to move this to the trans. section, if that's ok with everyone. :cheers:

dc,

I'm looking for just that, a matching OS for both the 60 and 80. Anyone have two clean files to save me some snooping? I want to experiment with this before we finish our turbo F-body project.

Thanks

Howard,

Here you go: 2002 4L80E OS 12212156 (http://www.holdencrazy.com/EFILive/TuneFileRepository/Stock/Chevrolet/2002%20Chevrolet%20Silverado%20Truck%20Automatic%2 0LQ4%206.0%20Litre%20(PCM%2012212156).tun)
2002 4L60E OS 12212156 (http://www.holdencrazy.com/EFILive/TuneFileRepository/Stock/Chevrolet/2002%20Chevrolet%20Camaro%20Coupe%20Automatic%20LS 1%205.7%20Litre%20(PCM%2012212156).tun)

[Redline Motorsports]

Hey that great! Thanks for the quick link!:cheers:

Let me see what kind of trouble I can get in!:)

[Redline Motorsports]

Seemed like it worked. I loaded the 60 tune and then the 80. Did the complete seg swap for both the trans cal and diagnostics. After I saved the file I did a compare to the new "swapped" file and the 80 file. None of the trans items came up as "differences". Pretty pain less!

Thanks again!

Howard

Good info. Just saved me a couple of hours of work:cheers:

[joecar]

1SH, did the 12212156 file work out (does your 'Hoe run...?)...?

[1SlowHoe]

It did! I drove it home today. I even did a little brake stalling and tire burning to ensure proper operation :D
EDIT: Actually I had to find the same OS. The 12212156 OS didnt work.

[joecar]

Cool... good job. :cheers:

What steps did you do...?

(edit: note to self: he started with 4L60E 12216125).

[1SlowHoe]

I took the tune from a 8.1L/4L80E, same OS as mine. 12216125
I opened it and my dyno tune, then just followed the steps in the segment copy directions. I copied the trans calibration and trans diagnostic segments into my dyno tune and loaded it in the PCM. I started up and ran great first try. It works wonders when you can find the same OS to copy from.
Thanks for helping me out:cheers:

[Superado]

what if you have OS 09381344?
this is the only missing link in my 4L80e conversion...

thanks!

For your truck, I'd suggest bumping up to an 01 or 02 OS before doing a segment swap. 12212156 for example. Could then run a COS as well.

[Superado]

got the 4L80e segments for my OS...
was very easy to swap segments and seems to work fine...

[joecar]

If it's ok with you, can I eyeball your file... ;) ...thanks.

[Superado]

here ya' go...

please look at it for the issue I posted in a couple other threads as well...

thanks! :cheers:

ANY suggestions are greatly appreciated!
very new to tuning...

[joecar]

Ok, thanks, I'll review thru it.

[rumblebox]

newbie question: how would i switch from a 09360361 to a 12212156 without having to do the tune all over again?

Open two instances of the tunetool (one on each file), and do copy-with-labels from one file and past-with-labels in the other file... there may be a table that needs to be transposed, use the tunetool's Conversions tab for this.

Go carefully, take your time, it takes about 2 hours or so...

when done copying, save the file, restart the tunetool and flash into the PCM.

Which year/model/vehicle/mods...?

[rumblebox]

sweet! thanks for the info.


it's a 99 formula with an LQ4, ported f.a.s.t. 90/90, COMP LSR 239/247 cam, QTP headers with 3" x pipe kit all the way out the back with dynomax bulles in front of the axle and borla xr-1s in the back, it just installed a strange dana 60 with 3.54 gears. right now it has a 4500 TCI converter in a stock(not original) 4L60. i have all the parts to do an 80 swap this weekend.

[joecar]

Let us know how your 4L80E swap goes, take pics if you're not too rushed/busy :)

[johnmaster]

Remember me:) Upgrading my slipping 60e to an 80e now and I'm not positive on how to convert my tune file. I have cos5 installed in the truck, how do I do a segment swap to a cos?

[ScarabEpic22]

I think you to seg swap in a non-COS OS (ie go all the way back to your GM OS), do the seg swap, upgrade that to a COS, then copy all of your changes in the current tune into the seg-swapped COS. I think, Im not sure how EFILive performs the seg swap stuff but the destination OS and source OS must match. Maybe try doing a seg swap in your stock GM OS, then upgrade that to a COS, then perform a seg swap your current COS tune and fresh GM OS w/seg swap.

Hope that makes sense...

If you have COS5 installed then the root OS has to be 12212156. Just use the compare feature with a 2002 Chevy HD Silverado from Tunefiledepot while having your current COS5 tune open. When selected you will get the edit feature open and will have the ability to "copy entire tranny&tranny diag" segments.

[johnmaster]

I hope it's this easy, going "all the way back" to my original os tune swapping segments and then coming all the way forward to the custom os sounds like about 10 hrs worth of work. This looks like it shouldn't take half an hour to figure out:) Will let you know how easy it was or if i run into any snags.

[johnmaster]

Wow, that was easy, next week I can see that it worked...I will put up a step by step but basically it was as doc said, having never even compared two tunes before I was a little worried.
