1.8T 4bar MAP scaled. More then 2bar boost gtx3071.  I  have this situation. But I do not understand why ECU cuts requested load. Only with high specified load. If LDRXN a little lower - all is ideal. I want to exceed the regulated threshold of 2 bar.
No ignition retards. Intake temp 32 C at this moment. Good fueling. Any ideas?

You should use RPM as x axis, and put things with very different values (req boost is very different from req load) on different y axes.

that graph is almost unreadable.

I assume KFLDHBN is the first thing you looked at?

this is KFMIRL and KFMIOP

i read it like that. Blue an red line.  Intake temp 32 C with meth injection
this is kfldhbn.

image changed in first post

If your tmot is 92C, what do you think the output of KFLDHBN will be?

Temperature input should be tsel (tans or tumc), not tmot, on ME7.5.

(Maybe I'm wrong)

KFLDHBN Y-axis is intake temp (tans), not engine tamp.

ah my mistake. thanks.

Torque intervention or KFMIRL is whack

Am I the only one that looked at his IOP?

but why after 6000 rpm rlsol_w meet rlmax_w anyway ?

you mean X-axis max 200? Do you think it could affect? Then why after 6000 rpm rlsol_w meet rlmax_w anyway ?

Your IRL and IOP are absolutely ridiculous. Tune them correctly.

На первый взгляд вроде все не так плохо )

Are you sure? Ok. I`ll try that

Там пиздец полный у тебя, убери парашу и сделай чтобы две карты соответствовали друг другу, после этого будет скорее всего всё нормально :)

Yes, I'm fairly sure.

I wish I did not paste this to google translate  ;D

I wish I were russian so PRJ was nice to me :(

(I kid, I kid)

в чем пиздец то? в том, что ось иоп не достигает максимальной нагрузки?
I`ll try this variant today evening:

В том что ты прохлопал факт что IRL это инверсионная карта IOP.
Тоесть значения в этих картах должны 1:1 совпадать, а не то что ты там на делал.

Если прочитаешь FR, то там конкретно это написано.

I think it would be really nice to see everyone talk in English.

Let's keep language specific talk to PM's.

Thanks :)

I will translate for you.


"First of all, IRL needs to be the inverse match for IOP. It doesnt have to be 1:1, but fairly close.

Open up the FR, you might learn something from it"

;)

 ;D

lol yeah I threw it into google translate and got the jist of it... but didn't want to insult by C&P it here ;)

я это знаю и очень давно. И если посмотреть, то карты соответствуют кроме верхней границы IOP. И обычно это нормально мозгами рюхается. Тем более, что на высоких оборотах все выходит.
Сейчас попробовал второй вариант - всё работает. По видимому именно большая дельта фактически запрашиваемых значений нагрузки от верхней границы iop дает такой эффект.

I know all of that. And I learned this a long time ago, before this forum. ) And only mistake is the up-border of a load axis of IOP map. But usually this limit is extrapolated normaly. Apparently it was a large delta actually requested load values ​​from the top value of iop axis gives this effect. That's why I put the table to understand how many people would say that. Today i try last variant and all is OK.

Nothing is ever "extrapolated". No Bosch ECU does "extrapolation". Interpolation yes, extrapolation, no.
The highest % the ecu can request is the last cell of KFMIOP.

no extrapolation, only extention... I always thought that it applies only to the most of secondary maps like ignition maps.  I thought ECU was not so stupid in this case, because in original file iop border is also smaller than max irl value, and there exists a possibility of extrapolation(interpolation in this case), because max load value exists in irl and ecu know it. But I was wrong)))

That is because the stock calibration does not reach higher load than what is mapped in IOP, therefore the map has been scaled accordingly to give more accuracy.

It's not really the load value that's limiting.

It's the torque value and what desired load that torque value translates to in IRL.

Also, keep in mind that the max torque is produced from rlmax.

Has author of this topic already solved this problem? modyfing KMIRL and IOP solved it?
I have similar issue rlsol_w is cutting actual load >4500rpm

...

author didn't replied so i will add info that for my load changing kmifrl and kfmiop in more properly way gives better results.
