4l80e segment swap
I finally got 80e in and it seems to be working ok no leaks. Does anyone have a tune or can walk me thru the segment swap? Right now its working off 4l60e tune but I am only pulling it in and out of shop. I would like to be able to go around my block but don't want to hurt trans by running 60 tune in it.

Re: 4l80e segment swap
I assume you using some software. Maybe hp tuners. You will need to get the OS system number from your ecm. Then match that up with one that came with a 4l80. Once you find your ecm number let us know and we can look for a matching one. I got mine from hptuners site. Hope that helps with the new software its not that hard but you do need to match ecms.

And, you probably already know this, but there are some wiring changes that need to be made as a 4l60 harness isn't a direct plug-and-play for a 4l80. |

Re: 4l80e segment swap
Yeah I got the 2 wires deleted and swapped one. I have the older style hp tuner and know very little about it , but will see if I can find what you are talking about.

You can update HP Tuners for free so I'd go ahead and do that. Then, you can load a 'compare' file -- which you have to be licensed for I think -- and there will be a segment swap section then at the bottom of the same menu you loaded the compare file with. Then select the trans and trans diag segments, and hit swap -- very easy. My license is for 2004 trucks, so I had to find a tune on the hp tuners website for a 2004 truck that had the 4L80 segment in it.

Re: 4l80e segment swap
do you know what year your engine and original PCM are from? i did a quick search and it is hard to find based on the os number.

Re: 4l80e segment swap
Thats a 411 ECM. The 411's were early in the run (99-01/2 I think) and are setup a little differently. Is your reference file (the one your swapping FROM) also a 411?

Re: 4l80e segment swap
Engine is 5.3 2002 . The ecm is from f-body 2002. The ecm that came with engine was bad, coil drivers would not work. I don't have a reference file to get one from. That is what I am trying to locate. Thanks.

If you don't, get one. Then login and locate the tune repository. You can find base flashes uploaded by the community. I would advise against ever actually flashing anything they put up, but use them as a parts bin/reference. Here are links to a couple of 01 v8/4l80e/2wd trucks. https://www.hptuners.com/customers/t...wnload&id=1355 https://www.hptuners.com/customers/t...wnload&id=1365

Re: 4l80e segment swap
Ok finally got it upgraded. I can see your files BR but I dont see where it says its a 4l80e. And what do I need to do just write down all the trans stuff and type it in my tune?

Re: 4l80e segment swap
The description in the repository lists both as 4l80e trucks. If you look at the actual repository, it has descriptions. I just direct linked the files (they aren't my files).

Re: 4l80e segment swap

you may need to setup an account like on here. This one is different than just coping some of the items over. With the swap it will write the "hidden" code and make it all correct. Just follow the steps and make sure your 2 PCMs match up and it is really pretty simple. I did mine and haven't had a problem with it. You will need credits to tune your original PCM which I assume you already have. You don't need one for the compare file. good luck and keep us posted Dave

Re: 4l80e segment swap
With a segment swap, you just select the trans segments and hpt copies it all over for you. There might be other things that get copied like the actual software vs. just parameters, idk.

Re: 4l80e segment swap
Thanks for trying to help guys. I had to upgrade my tuner to even read any files. Now it says I cant make changes to my files even though I have already licensed them. I sent hp tuners email and trying to get it fixed. Anyway how do I know if the files I look at on repository will work with my ecm if it doesnt show their ecm # ?

Re: 4l80e segment swap
I finally got tuner working again, found the place to id the os # like BR was telling me. I tried segment swap last nite. Using directions from hp turners site. I dont know if it worked yet or not. I clicked trans, trans diag, and nothing changed that I could see when I clicked import. Maybe it imported I will plug tuner into truck later today and try it.

Re: 4l80e segment swap
Finally got segment swap made, I was opening to many pages is the reason it wouldn't make the swap. I got my daughter to operate laptop, told her what I wanted to do. She had it swapped in about 5 mins start to finish. LOL I was at the right spot but didn't know which button to push. I tried it in truck and left 2 ruts in driveway, now I have 1st gear its been moving in 3rd or it felt like it.
Anyway thanks for all the info guys. Randy |
