Hello Guys,
I need a bit info about this map. Map id KFLDS.1 and KFLDS.0. Both of same values.
i think is it boost pressure regulation constant.therefore, this is releted with injection. it should be tune via engine load. am i right ?
How can i tune it correctly ?
as well as,my max throttle body position angel is 83 degree, but maximum vertical value looks 16.041. is it strange ? or thats normal...
And lastest rows has a same value.. why ?
thank you

What is your raw axis data and axis factor?

You need to click X-axis data source from "Eprom" to "Eprom, subtract". Does make much more sense that way |

I have a some new info about that.
lastest rows has a same value..Because, each motronic 3.8x 1.8T engine has a different max throttle angle values. some one 77degree,some one 86.. it looks always this range. Therefore lastest rows should be has a same value.
Another information, This maps generally related with fueling. But i had seen, it affect to ignition. Because motronic 3 iginition maps working for engine load. Engine load related with Turbo Pressure and MAf reading. when i reduced lower Throttle body angele values my cruise retard timings gone out.
I spend a lot of time for my car and motronic 3.8x tuning.
If you have a any experience about that, please share it.
Thank you !
Greetings,

KFLDS has nothing to do with Timing and fueling to me.
It is only related to boost control.
I understand it as requested "boost/load" (since ME3.8 doesn't have boost pressure sensor).

Exactly... these are the desired load maps.

Hi guys
I know this values for requested boost so engine load..
If it desired with engine load- it could be affect ignition. Because motronic 38x using engine load values for ignition.
I don't have a motronic 3 function sheet, therefore I never %100 sure.

Just to clarify:
The timing maps and fueling maps are sharing a load axis that is directly linked to the actual load, not the load requested by this map (KFLDS).

Thank you for your clarifcation. But when requested load higher the actual load I had seen 0,7-1.5 degree timing retard. I solved this issue with load request map. I had reduce requested load and problem solved. This is strange..

Not strange at all...
When you increase load it is natural that the advance is less than before (the original maps use loads smallers than the one in the last colum)... besides, when the pressure goes up the temperature rises and the IAT corrector lower the advance

What's the IAT correction map name ? is this map should be tuned for high advance ignition ?
Thank you
