OS upgrade... from 12593555

[wayneosan]

ok, I flashed that file, now how do I upgrade that OS?

wayneosan,

Did you full flash in 12587603...?

Read the attached doc, it specifically mentions 12587603 -> 040730xx in the OS table on page 4.

I flashed it in. I don't see any tables that are greater than 105kpa.
I don't see an option to upgrade that OS either.
Not really sure what to do.

Just follow the tutorial closely as it does go though the process completely.

Before you do anything you really need to be assured that you have been through and copied the tables from your original tune to the new one.

Basically to do the COS update you do the following:
- Full flash the COS operating system
- Cal flash the calibration from the OS# 12587603 tune
- Read out the PCM and save; this will then become your working file with the COS and calibration mated together
- Make modifications to the COS tables as desired
- Cal flash the changes

Also, fix any out-of-range cells in any of the Axxx custom tables.

thanks. I'll try again when I wake up. It was like a light bulb. Let me see, for redundancy sake, 1. load the 12587603 file because my original OS won't allow for an upgrade; 2. then flash the upgraded OS from my computer that matches. 3. then I'll have to (only in this instance), hand load my parameters and ensure there are no zeroed or WHACKED out tables.
Is that it in a nutshell?
What I kept tripping on was the custom os's. I didn't realize I had them myself. duh.

Basically to do the COS update you do the following:
- Full flash the COS operating system
- Cal flash the calibration from the OS# 12587603 tune
- Read out the PCM and save; this will then become your working file with the COS and calibration mated together
- Make modifications to the COS tables as desired
- Cal flash the changes

The blue part is where you have to hand copy your tables from your old file.

Some notes:
- when you full flash the COS into the PCM, the COS has all the tables zeroed (empty);
- that's why a cal flash is required, to fill in all the tables;
- after doing both steps (full flash followed by cal flash), read the PCM and save to file;
- that read/saved file will now be your working file, from now on you edit this file;
- in your working file, look at all the custom tables (A0000-A9999), fix any out-of-range cells;
- out-of-range cells have blue dog-ear corners; edit sane values into all of these, and save file;
- now copy the tables from your old file: open a second instance of the tunetool on the old file...
- when copying tables over, use copy-with-labels and paste-with-labels to avoid mis-pasting;
- when finished copying tables over, close the old file instance of the tunetool;
- now remember to save file;
- now cal flash to the PCM.

yes, yes.

I see said the blind man. The part that I kept missing was where I had to go to the folder "custom os"

I would go there and try to modify, or what not before I loaded them in to my ecu. Nice. Some thought went into that because they must have met someone like me before.

Anyway, I'll have results and possibly a dyno graph shortly. Loading custom os now.

hehe...

Let us know how you go...
