E38 CAX for "Open Loop Lean Limit" - OS 12628990

[krisr]

Hey guys,

Have been doing some searching and have come up short, i'm trying to find the "Open Loop Lean Limit" table which allows you to set the permissible lean EQ Ratio over coolant temp. The E40's have this PID (B0149) and i'm sure I have seen some E38's with it too. Would anyone know if this table is hidden away and/or have a CAX file to unlock this table by chance.

Cheers
Kris

What OS has B0149? I have never seen it.

BAM! That did it. How did you work that out? CAX noob here...

Hi Highlander,
That CAX file is the business. I have been looking for something like that. Doesn't work on all E38 OS though. Do you happen to have one for OS 12653249 or one for a OS 12656930. Alternatively, how do I alter the above CAX to suit other E38 OS?

...other than just renaming the CAX file of course.

Renaming the cax will not work, unless the OS you're renaming it to has that parameter/table at the exact same address, and with the exact same interpretation.

G'day Joecar,
Yep, got that. So what do I have to change in that CAX to get it to work in those other OS's?

The only way to map it to another OS is to dig through the OS code and figure out where that table exists in that OS.

Hi Erik,
Yes, not an easy thing I'm sure (certainly beyond my capabilities). Like Kris I was hoping someone had already created a CAX for those other OS's.
