goodevening guys,
I'm facing problem on engine load.
I want to command aroud 340%-350% and by kfmirl,kfmiop,ldrxn all should be ok in order to reach it.
but, as you can see on attached log, even if specified load is there (350) the requested remain around 310%
someone can help me to understand from where coming this limit. no any ignition retard faced.
thank you

ldrlts
KFLHBN via ldrlts. I set values maximum possible (3.98bar) even desidered pressure are more high than actual. maybe the problem is on my hack 5120? |

given that every single load variable is doubled? Ya, I'd say you screwed something up, or your .ecu is wrong.

Again, why are you ignoring the fact that your load readings are totally wrong?

Goodmorning, Right now I'm modifying properly the .ECU file of me7logger. I did as per your "my_8D0907551M-5120.ecu ". For all variables mbar I multiplied by two. afternoon I will log in order to see if engine load will read properly. load should be showed scaled as the boost pressure? |

like nyet said and i asked you about boost, something wrong in your file.ecu or in the 5120 hacked file. ldrxn is "aproximatly" your boost if you apply WIKI formula but in your last log it is wrong.

Wait, did you just change the .ecu file w/o doing 5120 ASM changes?
that's not going to work, because it doesn't look like the 5120 change (if you have it) is handling load correctly.

looks good but you are def limited by ldrlts
the hbd -> ldrlts (load) calculation is the inverse of req load -> req boost, but you can see it is significantly lower than rlmx, you're at the max of the hbn map. You will likely need to hack it out or scale hbn even more, or convert hbn to a direct load limit.

thank you to everybody.
right now I solved it by increase 10% the values on KFURL.
requested load now is properly high than real engine load.

this may have other unintended consequences. |
