Hi,
the map named KFMDBGRG stands for "Charge limitation based on gear", how does it work?
Can it be used for limiting the boost by gear (as the name says)?
On my .bin there are all fields 100.01 and it goes up to 6th gear...does it cooperate lineary?
For example if limiting 1 gear to let´s say to 80% of boost, will in never exeed this?

This map is a torque limit not boost.
It limits the torque request by gear which is then translated to load request in KFMIRL and finally converted to target manifold pressure.

Following here on "torque reduction based on gear"
my 1.8T engine swap (Lupo) needs reduced torque on 1st and 2nd gear.
According to FR, activation of KFMDBGRG by setting up CWMDBGRG (bit 1 = true).
Only changing KFMDBGRG wasn't successful.
I searched similar DAMOS files, but there wasn't any CWMDBGRG listed.
Defs to find in folder:
MDBGRG: 5.30 Momentenbegrenzung minimal -> min. torque reduction
so far I got:
19F5A DMRTMKI 1x1 Inkrement für Regelfaktor Momentenbegrenzung über Motortemperatur
19F60 KLFRTMKI 4x1 Kennlinie Regelfaktor aus Motortemperatur
279DC KFMDBGRG 4x7 Kennfeld mit dem Wert der Momentenbegrenzung
hope someone can give me a hint finding CWMDBGRG
Thanks

There is no CWMDBGRG in ME7.5.
I attach part of schematic showing relevant KFMDBGRG part.
Variables:
tmot - Engine temperature
yfzg - Vehicle speed
TMMIBGR - Engine temperature treshold for enabling torque limitation (original value: 0xff == 143.3 deg c)
VMIBGR - Vehicle speed threshold for enabling torque limitation (original value: 0xff == 318.8 km/h)
As you can see KFMDBGRG is only active when tmot > TMMIBGR and vfzg > VMIBGR. In original roms its 143.3 deg c and 318.8 km/h. Try to change them to something more reasonable like zero and KFMDBGRG should work.

That's what I first thought, and probably working for ME7.1,
the ME7.5 FR is showing:

try 0x819F18 for CWMDBGRG |

Thanks guys, the ori value on 0x819F18, set in my case, was already 18 = 2 + 16 -> bit 1 + 4 I' ve set/checked TMMIBGR and VMIBGR, tried again, but wasn't lucky -> no limitation based on gear  |

Maybe try to log mingrg_w and mibgr_w and check if there are some changes in them based on gear, that would narrow down places where to look for solution.
By the way, in my ME7.5(032DR) there is no CWMDBGRG your must have some newer revision.

Anyway try to set bit 0 of CWMDBGRG (to 0x13(decimal 19)), I analyzed your ecu code and it seems like it may help.
Edit:
Sorry, I made a mistake its should be inverse of it, so bit 0 should be cleared as it is originally. :/

It's from a 2006 Polo GTI (BJX), I wouldn't need CWMDBGRG to get the limitation going. Do you use KFMDBGRG on your 86C? Could make sence too  |
