Yes, I agree on everything you just said, but my point was that this directly relates to the LDRXN table values itself. Right, unless I'm missing something, this could auto-generate the proper LDXRN table for us. Any idea?
If you give me the formula how to calculate LDXRN based on KFMIRL/KFMIOP I might be able to create the auto LDXRN thingie  But basically if I understand everything correctly, you'd just have to find the highest load value in RPM range (KFMIRL) and then put it in LDRXN. And that's it  BTW: If you use my KFMIRL adviser and just put max bar it will auto generate kfmirl table. All you have to do then is just put (atmosphere+boost-300)/10 value where you want it to max out. |

Sorry, autogenerating LDRXN makes absolutely no sense to me.

Yep it's pretty easy to do once you have KFMIRL and KFMIOP sorted out... |

Maybe I'm missing something...its a load limiter. It limits filling. You can make KFMIRL whatever you want and if its below LDRXN, then LDRXN does nothing. If KFMIRL is above LDRXN, it will limit filling to the values in LDRXN.
It doesn't have any real/hard relationship to KFMIRL unless you want it to for some reason.

s4wiki:
"Specifically, on a full throttle pull, your boost profile will follow LDRXN. K03s and K04s have some severe flow limitations, so unlike big turbos, you will want your boost to taper (not ramp up) to redline. ECUxPlot has a pressure ratio/flow plotter that you can use to compare against your turbo's compressor map."
how then is it unrelated? it sounds like the OP specified an algorithm to auto-generate it a few posts back... is anything wrong with what he said?

back tracking P/R to req boost to req load is unrelated to coordinating IOP with IRL...

KFMIRL is not used to tune a curve to avoid surge/etc. Its used to correlate a torque to a filling at a speed. It doesn't care what turbo is on the car/ where the surge line is. LDRXN is used to tune the filling curve, and this is what you use to avoid surge, etc (or other boost limiters). There is no relation between the two where you would use KFMIRL to "generate" LDRXN. KFMIRL is a description of the physical system. LDRXN is a tuning parameter.

OK, clearly I need to do my research on my comment earlier...

Is there a way to adapt to be used with the KFMIRL of the M-box for the S4?
The load points are less then what you have unless I am misunderstanding something?
Mbox KFMIRL load axis: 0,10,14.9,19.9,30,39.9,50,60,69.9,80,89.9,99.9
Thanks!

Are you talking about KFMIOP calculator v1.1 or KRMIRL adviser v1.0? |

Both, since you have too many load sites in your excel file (16 vs 12 needed for the S4).

thats correct, the converter exists, but the adviser doesn't. is there some way to edit all of those cells?

copy whole adviser sheet to a new excel file and you'll be able to edit every cell |
