Me7.2 XDF and bin (other goodies if yall want them)

[zarboz]

I have a XDF for the me7.2 running the m62tub44

the XDF was generated from the WinOLS project floating around for the e53 x5 and cross referenced against a dump of my e39 540i


It's rather extensive you can find the funktionsramen for the me7.2 used in the 540i with some googling

forums wont let me post


Enjoy Now My hunt to understand WHAT to tune starts

Also a collection of BMW Xdfs make sure to clone recursive as I have added other gits that are maintained by other folks

some Damos files and A2L files

I have been comparing my 4.4 liter motor file with a 4.6 liter motor file with Dinan tune applied

I have found differences in these tables:

UBDCAN->UBatt threshold for diagnosis CAN timeout
ZLUTSFI->Time constant for filtering uneven running test size
TLAED->Waiting time for detection condition 'driving cycle'
MDNORM->Maximum indexed engine torque for torque normalization
TKATSAN->Catalyst temperature threshold for fuel cut f (nmot)
CWMDKOG->Codeword MDKOG: Ignition angle retardation at negative pressure limitation
DMRKHO->upper Hytereseschrieg Katheiz torque reserve with ZW intervention
DMRKHU->Lower Hytereseschrieg Katheiz torque reserve with ZW intervention
NKUPZWEO->Upper speed Hyteresis threshold for KUP-ZW interventions
NKUPZWEU->Lower speed Hyteresis threshold for KUP-ZW interventions
NLLZWEO->Upper speed Hyteresis threshold for LL-ZW interventions
NLLZWEU->Lower speed Hyteresis threshold for LL-ZW interventions
ETADZW->ZW efficiency as a function of delta ZW
ETALAM->Lambda efficiency
KFZWOP->optimal ignition angle
KFZWOP2->?optimal ignition angle variant 2
NMAXPG->gear-dependent P element in NMAX control
NMXDAEF->Maximum speed for throttle drive replacement function
TNMXPRG->gear-dependent speed prediction horizon for NMAX control
ZINMAXG->gear-dependent I-slope for NMAX control
RLMNN->Characteristic minimum filling
RLMNSAN->Characteristic minimum filling in thrust
ZETABASN->Low pass filter time constant for etabas_w
DZWETA->Delta ignition angle from efficiency



I am still digging and translating will update this post later

Github heavily updated


I have been playing with my 540i and got great results I only have a functionsheet for the ME7.3 and ME7.1 (not for the ME7.2) so some items still need deciphering before they are added to the XDF
