Default 2002 Silverado - 80E segment swap?

Did a fair amount of searching but wasn't able to find an exact answer. I have a 2002 Silverado that came originally with a 4.8L and a 4L60E, 2WD. The 4L80E has been mechanically swapped in and I'm aware of the wiring change I need to make at the round trans connector as well as the PCM pins.
What I'm unsure of is whether or not I need to segment swap this PCM. This truck could have been originally optioned with an 80E if you got the 6.0L (1500HD) and thus there is a option in the drop down trans menu for 80E. I am assuming I still need to do a segment swap regardless?
Thanks,

You will need to segment swap it for the 80 unless you re-wire and use relay to run the 80 on the 60 tune which isnt as common.

Nah, screw that relay stuff. I'll segment swap it, just need to find a compatible file...is there a 3bar 80E flex that will work with a 2002 P01 PCM?

Here's a segment swapped 80 stock tune, from a 98-02 camaro. Bone stock. From here you can just change the OS to a 3 bar and should be off to tuning.

And yes, for the ol' 0411... P01

Just realized you needed flex too... That tune won't work for that, but the segment is there. Hopefully it's compatible for you.

Thanks!

Can this tune be used to segment swap my original 2002 Silverado tune? I'd rather not flash that tune to my PCM since technically I think I'd have to license that file and burn up 2 credits.

Flex is not a huge deal...I can just fill up with E85 and tune for that alone since this is not a daily.

Yes you’d have to license it. Hpt has a segment swap option built into the software now. It’s worth a try. Been a long time since I’ve had to do that so I’ll try it and get back to you. In any case, you can license that file, then copy your tables over to it, after changing the OS to 3 bar. Doing that changes a few tables.

Take your licensed 2002 tune and compare it to the one posted then do a segment swap. I dont think it will charge you any credits, we have unlimited so I have no way to test it 100%.

It's free to swap the segment... You just need the segment. You could also try downloading one for a Silverado or something too, if that one is not compatible. It should be compatible though. It's pretty easy, and yes, under the compare feature in the tune. Just open YOUR file you wish to change first, then open the one I gave you, or a stock Silverado one or something similar with the 80E segment, select "segment swapper" and then select transmission. Should be it. Make sure you back up everything beforehand, it doesn't always work out from what I hear. That particular one works perfectly fine though. It's been a while since I did it.

Here's a video on it.

We have been tuning efi almost 20 years now, we purchased unlimited alot of times and some times just got it from tuning enough of the same vehicle. It was nothing that happened over night though. Between SCT, HPT, SPS and EFI we have spent a fortune on licensing over the years but its worth it because without them we wouldnt be where we are today.
