KFMIOP map is one of the difficult understanding map. It cannot stand alone when calibrating and there is no possibility to have maximum load request if you leave it to 85% for example.

Maximum tuning of this map becomes only if you set load axis at ecu max load (191.7 at ME7) and the value at these RPM 100%!
Becareful because if you DON'T recalibrate the whole map at low and mid loads and low and mid RPM correctly, then you may have part load issues.

Of course you can say "Dude, I will deactivate torque monitoring and all will be fine"
Nop! It will be run a little bit better but not as smooth as stock. You can check it on your own, drive the car with low loads at part load 120-130% and go to block 003-060. You will see the throttle playing and the accPed stable Wink

Bosch isn't stupid to leave torque monitoring enabled.


The best in my opinion is to calibrate correct the KFMIOP and deactivate torque monitoring ONLY if you go further than a simple stage 1st file!

I really wish that people would stop perpetuating these myths.

The axis is NOT a charge limit.

You'll definitely know it if you have level two intervention.
Correct.

Tune KFMIOP properly and you will not ever have to mess around with torque limit maps or deal with level 2 intervention.

Yes yes, but my point is these guys aren't touching IOP. Conventional wisdom would suggest massive intervention. Thus, the thread!

Do you know that they aren't getting torque intervention at part throttle?

Anything else torque related touched?

Is load underscaled?

How aggressive is LDRXN?

Very aggressive. I'm happy to post screenshots of specific maps, tell me what you want to see.

EPL underscales load, at least from what I've seen.  Stock-ish MLHFM for 85mm MAF + ~.07x KRKTE for 52 lb/min injectors.

Hm... i always do rework on whole kfmiop and kfmi_um (easiest way is jyst to change its axes to be same as kfmiop and then fill the table with kfmiop values). And whenever i tried touching kfmiop without doing kfmi_um i got lvl2 intervention (basically acc pedal gone Cheesy)

Dont know if theres easier way doing this buf for me it is always kfmiop==kfmi_um == no lvl2 intervention and agressive as f... part throttle. Oh and i always have to rescale all the other maps that share same axes.

You get level 2 intervention because you FF the level 1 torque limit maps.

Who said that axis is a charge limit??? You just create a more detailed map because you will run at higher loads.

What are you using to checksum when changing the UM maps?  setzi's checksum will not correct when I touch these.. Are you using nyet's checksum corrector?

John, you're using the wrong definition for that file.
