Alright. I'm trying to wrap my head around all this.
I've tried to find it but apparently haven't been able to.
Can someone please explain to me how I find the software version of my Dme so I'll know what xd to use? I have a bench set up and a spare dme to play with before I start on my car.
Thank you

download the 64k file from your ecu and open it with a hex editor

i'm installing the next days an lc-2 wideband lamda.
i have cat configuration "1" since i don't use cats, so there are only 2 pre-cat sensors.
can i put the wideband in one post-cat position without changing cat configuration?
Wiring diagram for MS41:

I'm running single-band pre & post cat, so I will attach the map to the precat bank 2 and the WBO2 to the postcat bank 2 inputs.

Precat polling is 10ms, postcat is 100ms, keep that in mind.

I hope that the DME will ignore the inputs for DTC, otherwise it would be pretty useless.

Do not connect the o2 sensor heating PWM ground to the normal KL31- Ground, otherwise you'll get errors for heater short.

well if there is so much difference in polling, i'll use one pre-cat connection.
but i don't understand the reason for DTC.

getting closer.
I have sorted some of the digital data.
you can now trace idle and part and full load maps.
you have to setup each map to data tracing. see picture.
if it is a part load map select Part LOAD and Part LOAD RPM.
rename file to adx.

ok there is a little misunderstanding about DA Assoc.
eg go to map "Intake cam setpoint, warm engine, part-load".
right click. select edit parameter XDF info.
select DA Assos.
X Axis DA Link. Link Mode = Explicit. Select X Axis DA Item = Part LOAD.
Y Axis DA Link. Link Mode = Explicit. Select Y Axis DA Item = Part LOAD RPM.
Select ok.
if the map is open, close the map.
save XDF.

if it is an idle map select "Idle LOAD" and "Idle LOAD RPM".
if it is an full load map select "Full LOAD" and "Full LOAD RPM".
You must do this at all the maps you want to trace.

Engine was without load, so no changes on the x axis. ;-)

the adx works only with 430056 version?
