Bringing up an old post, but looking at getting the MTrack mode on the Z4MR this summer.
I want to get it correct, and what Beedub posted makes sense. Was this ever fully resolved, ie what needs changing to get full fat MTrack, and not just the 3.0 Si version? It doesn't seem as simple as simply changing
TRAKTIONDIFFERENZREGELUNG = aktiv
I know for example one setting is different between the Coupe which has the CSL rack, than the Roadster so
LENKWINKELKENNLINIE_2 = wert_04 for Coupe and
wert_05 for Roadster.
I would like to understand these entries, mentioned by Beedub. In brackets is the setting for the standard M3, not in brackets is CSL/CS
UEBERSTEUERN_MUE_1_2 = wert_11 (wert_09)
UNTERSTEUERSCHWELLE_2 = wert_04 (wert_05)
UNTERSTEUERN_MUE_1_2 = wert_03 (wert_02)
Whilst researching, also seen mention of these settings
DTC_LAMPE = aktiv (nicht_aktiv) as we dont have the M Track symbol on the dash, I belive we need this set to
nicht aktiv, which it may be by default anyway
PRE_MSR = aktiv (nicht_aktiv) - unsure what this is
BAUART_MK60 = csl (coupe_m or cabrio_m) - ?
DRUCKMODELL_HINTERACHSE = typ_3 (typ_2) - typ 3 is for ZCP brakes - I know we have CSL discs, but does a Z4M have ZCP calipers? (I am thinking yes, as the rear caliper on the Z4M is the same part number as the CSL, and has a larger piston than a standard M3)

FWIW just noted the m3 guys are able to get the actually M-TRAK light , some are getting the DTC light, but it seems this light can be activated too, anyone tried this one the z4m platform ??? guessing our cluster may not have that bulb.

also to get the DTC set so its actually cutting in and out at he CSL spec M track we need to change these settings.. to these but they appear different in our data, so I'm not totally sure what we are activating in our instance but its definitely not the higher thresholds that the CSL have without changing the below... we seem to just be adding in the function from the 3.0Si which id guess isn't optimised for the M-diff...
UEBERSTEUERN_MUE_1_2 - wert_11
UNTERSTEUERSCHWELLE_2 - wert_04
UNTERSTEUERN_MUE_1_2 - wert_03
all info in the above thread.
turning on TDR isn't changing any values of the understeer oversteer cut in and outs i don't think, but not sure how to check???
is this a way to check the valves for the DTC mode?? and where do i change them, i can see the above germans sentences in the mk 60 module but how do we know if thats for the traction fully on, DTC , or the OFF mode settings?
Edit... after reading up on DTC we are definitely at a high wheel slip allowance.. so will try some different settings and report back,.
are you far from Laindon?
