The UM maps will never interfere unless you mess with the maps from MDZUL.

The only reason you would have for that would be if you did something crazy with KFPED or KFMIOP.

mimax_w is KFMIOP from rlmax_w (LDRLMX - LDRXN corrected)

mivbeg_w is mrfa_w(mimax_w - mimin_w) + mimin_w + dmllri_w limited by MDIMX

mivbeb_w is min(mivbeg_w, mimax_w)

mivbeb_w then goes through a slew of potential interventions and finally gives mifa_w.

mifa_w then goes through MDKOL and is subject again to numerous interventions finally giving milsol_w for KFMIRL.

KFMIRL will request the air charge you set for a given torque request.

Am i able to use the same ones as in KFMIRL?

Yes... but I did like my layman's terms description

Can I label the axis to match what I have seen online, or do I need to find the hex address for the internal axis parameters.

What do you mean by that?

If KFMIOP and KFMIRL no longer more-or-less match the ECU will not be able to request a given torque anymore.
If you want to request more load than the last column in KFMIOP you will have to change the axis.

One side effect of getting this wrong, is an ESP system that is completely useless.

Not the case on my car when I have smaller scale traction problems in 3rd gear pulls on the road.
There is intervention, but very little of it. If the top end of the map is messed up, I get hard cuts. In fact the intervention is almost not noticeable unless you eyeball the ESP light.

And the reason is simple. If your KFMIOP axis ends at 150 load, but you request 200 load, then anything over 75% will be the same value.
Yes, you can request enough load, by just filling 75% to 100% in KFMIRL with 200, but for example the ESP will not be able to finely control the torque request.

It will see during the first request that it has no effect, and during the second request you will get a hard cut because mivbeg_w will be very low.
Basically the function is supposed to be a pretty literal inverse. And it is that on all the factory cars I've seen, give or take a percent.

Otherwise the torque can not be dialed back and forth correctly. Not a problem if you are regulating it with your pedal, but a huge problem if it is needed for ESP.
The load axis of KFMIOP should represent a good distribution of actual up to rlmax. It should never top out on the last cell during the operation, as it is no longer possible to adjust torque past that point (due to the hacks you will need to do to KFMIRL to make it work).
