B_krldya is bit 0x00FD8C.15
B_krldyv is bit 0x00FD8E.2
zaldy is 0x380C51 (Byte)
The FR states that B_mf exists just for representation purpose
in the documentation, but is not present in the SW.

Thanks. I'll be back on the dyno saturday, so that should speed this effort up significantly.

Sorry Rick. My dyno day got pushed back a week. Hopefully I'll have more this weekend.

I've tried to understand connection between KFMIRL and KFMIOP but failed. I've upped about half of my KFMIRL map, but don't now how to change KFMIOP. Please look at attached image and tell me if my kfmiop needs updating or not...

could you be a little bit more specific? Because I've read this whole thread and still don't understand how one map relates to another? I mean is there some kind of formula to calculate KFMIOP based on KFMIRL?

In IRL you are requesting 204 load for an 85% torque request.  In IOP you are saying that at 85% torque request you are only going to have a load of 140...

sortof, but i'd reword it to say

In IOP you are saying that at load of 204, your output torque is 99%, which is higher than 85%, which results in the ECU interfering to reduce output torque.

Oh, now I understand it... sort of Smiley So if I update IOP X axis at 145 to 200 it should be OK? Smiley Can I just edit axis instead of editing table?

so if I understand correctly I have to update tables to something crazy like this (image attached)

In theory, yes Smiley

BTW the fact that you immediately came to this conclusion means you have the same understanding of IOP that I do, right or wrong Smiley!

I think some have taken the approach of editing the whole table by hand.

I was THINKING about writing a program to generate the proper inverse (along with a rescaled axis) but never got around it it.

I, personally, have not really played with IOP since my IRL is nearly stock.

Well, let's hope that we understand this right Smiley

Program would speed up whole process that is for sure... Smiley Maybe excel could do something like this? Oh and by the way, I have edited both the table and x axis because I wanted some nice numbers in table Smiley

So my KFMIOP and KFMIRL tables look ok to you? Smiley I think that now IRL will not limit my boost up to 1.4 bar or something like that...

Yea it looks like you are on the right track. Please let us know the results! BTW it shouldn't affect your boost, only timing.
