I have a file but I can't upload with this new upload manager attachment shit!!!....Sorry!
I'll e-mail you a tune file...

Upload Files -> X -> Insert Attachment

Do you need a modified file or just an OE?

[GAMEOVER]

I tried Joe... When I click on Upload files nothing happens...:confused:
I'll try again though...

[GAMEOVER]

I re-loaded Mozilla FireFox and got it to work...:doh2:

[L31Sleeper]

Thanx Gameover I realized I already have that file. What I am looking for is a 4LO shift table ??
The only thing I can find on the 12212156 OS is a 4 LOW WOT rpm
Is there a 4x4 Module ?? or does the body control module have anything to do with this ??

[5.7ute]

There are some low 4 parameters in the tune file that I can make a .cax file for. You will have to give me a while though.

[5.7ute]

O.K. Here is a .cax file for the 4 low trans parameters. At the moment they are in their own subfolder 4X4 shifts. Once proved I can move them to the necessary folders.
Before modifying, please log & confirm the accuracy.
Cheers Mick

I don't see the sub folder

[5.7ute]

Did you unzip it into the C:/program files/efilive/v7.5/calibrations folder. You may have to rename it 12212156.cax .If you still have trouble PM me your email address & I will send it through.

[L31Sleeper]

Thanx I was trying to put it into C:/program files/efilive/v7.5/calibrations/LS1B
Your upshift at RPM table already exists {D0969} 1 -> 2 {D0970} 2 -> 3 and {D0971} 3 -> 4
Is there a way to make the VSS table KMH vs TPS like the other ones ?

[5.7ute]

I will look for any others. But all the .cax file can do is translate what is already in the tunes .bin file. Changing to tps/kmh would take major code changes, something I do not have the skills, let alone time to do.
I will remove the upshift rpm table from the .cax as you already have that.

[L31Sleeper]

So does that mean the factory tune does not have a part throttle table ??
If you made a table for something that is already there wouldn't the data be the same ?

[5.7ute]

Having a quick look they are actually different tables. The ones you are talking about are under WOT. I will be back to you shortly with an answer.

[5.7ute]

Delete that .cax file. They are all already supported.
I cannot find any other parameters for 4wd low. Unfortunately what you see is what you get at this time.

[L31Sleeper]

Thank you very much for your effort !! but I'm forced back to my original question, is there a 4x4 module, BCM, or no part throttle table for 4 LOW ?

[5.7ute]

There is no seperate part throttle table for 4 low that I can see. However it is quite possible that the pcm uses the standard or performance settings while in 4 low. If this vehicle is running you could take some logs that we could look at.
Either way I will keep searching.

[L31Sleeper]

I don't have a running vehicle at the moment, I was doing research for a friend. So far we've (www.pacificp.com/forum) only come
across this problem during a black box to 411 PCM swap. The guys with 4L60s were able to use S-10 code to make it work but since
the S-10 never came with a 4L80 I'm not sure what to do. If it used the standard shift table it would never make it to the KMH the table
is looking for and thus shift via the max RPM table.
