Not impossible but difficult.   All the info is in this thread, you need to disassemble the file to see what is going on and how you can subvert it.

Somebody please help find limiter for 1 and 2 gears. I found KFMDBGRG but boost is not maxxed in first gears.

Thank you all!

It's been a while since I did Volvos and changing gear dependant boost. Have you loked at MKMXGx (where "X" is the gear)?

Yeah, I thought we were talking about earlier Volvos? I've seen model years from 99 to 01 flying around in the questions... :-)

Right so here's a log from VIDA with some annotations Smiley

Between 3000-4000 rpm it seems boost increases by around 100 hpa and I still have problems with torque monitoring. I still get DTC (actual load > req load) at ~3640 rpm. I have also made a flash revision where I aligned KFMIOP with KFMIRL using the Excel Tool available here but I still see this increase in boost at 3000-4000 rpm and the same torque monitoring issues. This leads me to believe that KFMIOP itself is not the map to tune to get rid of the torque monitoring issues in my case!? KFMIOP axis is not altered.

I have not modified KFLDHBN yet since I want to work out these torque monitoring issues, so this might cap load I guess (attached below).

Im also attaching my LDRXN table and graph.

Ideas are much appreciated.

Could you post your KFMIOP as well as KFMIRL map data? A screenshot will do just fine.

TM would cause odd timing no?
I think you're exceeding the limit set by DLULS. Increase at about 3500.

Oh yes, increasing the error limit for a self made error...  Right way?

KFMIOP and KFMIRL is the same as in the previous post:

Sorry. Didnt think when replying. I guess best approach would be to tune PID to match requested and actual

Also that IOP doesnt look like its properly made.

Last two columns are lowered from 2500 rpm and up in order to try to avoid actual load > requested. The map it not fully aligned with KFMIRL. I am running a fully aligned map right now in the car but I'm seeing the same problem.

You are seeing what? Car goes into limp or you feel something?

No, no limp mode. The ETS (eletronic throttle system) light comes on during WOT at around 3600 rpm and at the same time a DTC is stored. From the logs it look like the timing is pulled. It is interesting however that the DTC seems to have been removed in later software releases. To me this diagnostic feels pretty handy since I have limited logging capabilities.

Diagnostic trouble code (DTC) information

Condition
To check that the engine control system reacts as intended, the Engine control module (ECM) monitors continuously that requested torque from the engine does not become too high. To do this, the Engine control module (ECM) calculates a maximum allowed torque which is based on accelerator pedal angle and engine rpm. This torque is then compared with the requested torque. If Engine control module (ECM) registers that the requested torque exceeds the maximum allowed torque for longer time than 0.3 seconds, then diagnostic trouble code ECM-980A, Too high torque, is stored.
For upgraded software, released during year 2006 or later, this diagnostic trouble code is no longer necessary and therefore has been removed.
Identifying upgraded software ECM/ETM 

Substitute value
torque limiting

Possible source
defective engine control module (ECM). 

Fault symptom
none
