Anyone have a 4L80E program?

[Telco]

Update - Danged if I can figure it out, but I can't get the program to smooth out. So, I started reading up more on it on this site. Then it struck me - the engine is old and has problems, has vacuum leaks, ect. From what I've read, these leaks are probably causing my problems since the computer isn't getting signals consistent with what the engine is doing. No problem though, my new engine is sitting down at the rebuilder as I type this, and with any luck I'll be slapping it in there around the start of April. Hopefully, when all the mechanical problems are resolved, I'll be able to get the programming straight.

Just found your file from earlier in this thread, I see your truck is a 2000. Why not use an OS from 2002 like the popular 12212156? It should be more refined than the 2000 OS plus if you ever want to go to a COS its easy. Not sure you want to add another thing into the mix right now though!

Attached is a stock 02 12212156 OS file with a freshly copied 4L80E trans and trans diagnostic segment. I also put your VIN in, but didnt change any of the tables around. If it works for ya, great! The IFR is different between your tune and this one so I knew there would be a few things to move around. If you want to use it, open your old file and this new one and copy all the values from the 2000 tune to the 02 one.

(BTW, are there any advantages to running say an OS from 03 vs 02 in a 512kb PCM? I know most people use the 12212156 OS because its great for Vortec swaps with the Express van tune, but what about regular trucks?)

I can give it a shot. I'll report back on the results.

Incidentally, I've been trying files from up to 2007 trucks. Haven't been able to find a newer file than that with a 4L80E, seems everything newer that HoldenCrazy has a file for either has a 6 speed auto or a manual trans.

Hi Telco!

Did you get your problem figured out?

I am very interested in the outcome.

I also have a 2000 Silverado Z71, with 6.0 engine, comp cam, Eaton TVS 1900 supercharger.

Ive been thru 4 - 4L60E's in the last 1000 miles!!!

I am swapping in a 2004 model 4L80E as we speak.

Im in need of help with adding the 4L80e segment to my custom tune.

Can someone help me here and do the segment swap for me with my attached tune?

Im just too nervous right now to fumble thru it as ive spent lots of money lately on this truck and i would have a heartattack if i broke anything else!

Any help is appreciated!

Thankyou in advance.

Fix the out of range cells first man, there are a LOT of them!

If you can find a tune with the same OS as yours with 4L80E I can do a seg swap for you, if not then you might have to go to a different OS that has a 4L80E tune available to do a segment swap. Like a 2002 OS.

Thankyou for the reply, your time, and offer to help. I really appreciate it!

Not sure how to fix the out of range issues, Im afraid to change anything that may mess up the tune, the truck runs awesome and has great A/F ratio .

( I wander That since my tuner uses Tunercat and HP tuners to tune my truck, and since i copied the tune into my EFI LIVE software that this is why values are out of range?? )

I Guess i need to find somewhere that has a 4L80E OS thats the same as mine?? Maybe holden crazy, i will do some looking.

Thanks again for the help.

OK i found The same operating system for a silverado with 6.0 and 4l80E , a 2000 model year, On holden crazy. Hope this is the correct file.





Thankyou. I will work on getting the out of range parameters delt with!

Ok, I got it figured out after some searching and reading!

I found the segment swap sticky at the top of this section ( Imagine that !! ) How cool, it was easy!!

Thankyou all for the help in the meantime. Im really excited to be doing " stuff" like this as i am such a newb and scaredy cat when it comes to adjusting my tuning!
