need B9021 for 01250003

[BLK02WS6]

Is there a .cax available to give me table B9021 for 01250003? Thanks!

[Lextech]

I have looked through all of my stuff. I don't have one---That doesn't mean one doesn't exist. What year OS is that one based off of?

Jeff

[BLK02WS6]

Thanks for looking! It is based on a 2001 OS...

I had this cax file, but I don't know what is in it.

[joecar]

The only cax files I have for B9021 are for 12212156 and 12202088...

B9021 has not been yet reverse-engineered inother files yet.

Just out of curiosity, I took one of those and renamed it 01250003 - you can then see B9021 - is that not a good thing to do? I just did it on my home laptop to see what would happen, not on my tuning laptop...

Not B9021...

Thanks!

Okay, thanks!

[5.7ute]

Thanks!
No worries.
There are three different addresses for B9021 that I have found so far. This makes it easy as it means I only had to write 3 cax files, & you just rename the correct one for your OS & away you go. The list is as follows.
Cax a
Stock OS
12202088
92111922
12208322
Custom OS
0125000x
0127000x
Cax b
Stock OS
12209203
12212156
12225074
Custom OS
0201000x
0202000x
0129000x
Cax c
Stock OS
12221588
12593358
Custom OS
0203000x
0204000x

Cool :cheers: thanks Mick, narrowing B9021 like that makes it easier.

[BLK02WS6]

Thanks - that is awesome! :cucumber:

[MICK]

Nice work!!!! Great to see the good guys helping out pushing the edge.

Cax file updated with 12592618 & 12587603 files.

[BLK02WS6]

Thanks for working on these 1MB cax files Mick! It is a huge help to some of us! Great job!

[Lextech]

I'm confused. The first 3 cax files show they are for the same family of OS yet have different Hex addresses for the B9021 parameter???
1. The 12587603 cax shows it is for a 12202088 OS and a Hex address of C00E.
2. The 12592618 cax shows it is for a 12202088 OS and a Hex address of BD20.
3. The cax A shows it is for the 12202088 OS and a Hex address of B630.
4. The cax B shows it is for the 12209203 OS and a Hex address of B632.
5. The cax C shows it is for the 12221588 OS and a Hex address of B634.

Hi Jeff. I just did not edit the internal descriptions. These have no function at all.

Thanks Mick,
I thought that might be the case.

Adding 09373372.cax from 60lb-injector-woes-chicken-or-the-egg&p=210270 (https://forum.efilive.com/showthread.php?24606-60lb-injector-woes-chicken-or-the-egg&p=210270#post210270) post #26:

Thanks Mick.

Cax file updated with 12592618 & 12587603 files.


If my original OS was 12587603, and I have since updated it to COS3 (4073003) will the 12587603 cax file work if I rename it to 4073003?

[Taz]

Hi Jim,

I has been awhile since I mapped out that OS - I think the COS has a leading zero (i.e. 04073003) - so if you rename it to 04073003 it should work - just use caution until you are certain.

Yes it does work! -- Joecar posted this last year about the same issue and I eventually found it -- Thanks! --

"take note: each COS has a base OEM OS, meaning that you can rename the OEM OS to the COS's id."

Help! Can anyone make this CAX for a 12579405 os? Or is there a good os that is compatible for my truck? 2003 LM7 Silverado.
