Hi, i´m working on an 2.0 ALT NA engine just for fun. First i tried to delete the regulated thermostat because i removed it. I found ESKONF via stupid pattern search and it seems to be 4 times in there. has this some importance, is it needed to change all? Thanks in advance!

edit 19.8.2024: added some maps ( like max. throttle angle) and some prokon values, the ones with ? at the end are wrong
edit 23.8.2024: added map and Axis for Saugrohrumschaltung (works); inlet camshaft maps are also working, thanks to gremlin

Hi again, done some work on this na ecu but making almost no progress. i found some maps but not sure if they are correct:
0x1C47A - Pedalkennfeld MR (KFPED)
0x156AA - Kennfeld für Berechnung Sollfüllung ((KFMIRL) Engine load desired)

still searching for inlet camshaft timing maps but what i found looks weird:
0x17846
0x17924

lamfa map found from maplocator also looks wrong:
0x1D304

maps are in updated xdf of 1st post

Would be great if someone can please confirm if they are correct. Thanks in advance. prog

Not correct.
Pedal maps set are
KFPED -> 1667C
KFPEDL-> 167FC
KFPEDR -> 1697C

Camshaft timing maps does not exist in this firmware.
Your addresses
0x17846 -> KFZWMNKH Min-Zundwinkel Katheizen
0x17924 -> KFZWMNST Min-Zьndwinkel fur Start und Nachstart

Wrong definition.
LAMFA -> 1D9AE

Big thanks to you, this helps a lot.
The engine is an 2.0 ALT NA with continous inlet camshaft variation like on 3.0 ASN (8E0909559x) so in some way there should be a map for this function but i have no clue on how this map should look like.
I tried to open the ols file posted on this forum for an ASN but my OLS version is way too old for this

I tried to determine the camshaft timing maps.
It seems (with 95% accuracy) the maps are located at the addresses shown in the screenshot
