Programming the DSC MK60 for LSD

[wertyu78]

Interestingly enough, I found this option on the MK60 DSC unit awhile back. Now that I have a LSD, I will enable it.


"LOGIK_HA_SPERRE"
Logic Limited-Slip Differential


Has anyone changed this to Aktiv, and know of any benefits this may yield? I am going to change mine over to Aktiv now... Will report back!

Update:

I've set "LOGIK_HA_SPERRE" to Aktiv. Going for a drive soon

SPERRDIFFERENZREGELUNG (Differential Locking Control) is set to Aktiv normally, but standard E46 M3 is set to nicht_aktiv. I've set mine to nicht_aktiv.

TRAKTIONDIFFERENZREGELUNG (Differential Traction Control) is set to Aktiv normally, standard E46 M3 is set to nicht_aktiv and E46 M3 ZCP is set to Aktiv. I've set mine to nicht_aktiv.


Update 2:

I've not yet driven the car, but I've started it to test the disabling and enabling of DSC. Now I only have one "mode" of DSC. Holding it for 5 seconds doesn't illuminate the BRAKE light yellow anymore.

Update 3:

Driving the car is a blast with the LSD. The DSC system does work differently with the M3 settings, but I'm not able to find a way to describe it. It's convenient to have a simple on/off 1 button press to enable or disable the DSC.

[wertyu78]

There are a lot of other features that we may be able to edit such as.... Under-steer and Over-steer friction coefficients, under-steer and over-steer algorithms, etc.

I'd love to have a lesser traction control setup but keep the well engineered stability control as well as the ABS.

[JupiterBMW]

I love playing around with coding, but I will not mess with the stability management systems... I'd hate to have an unfortunate situation due to a crash because of improperly set traction/stability management...

BUT, good luck and have fun! Report with everything you learn... :thumbsup

[wertyu78]

Seeing that the three earlier mentioned options are OE configured, I'd feel 100% comfortable to changing those with the LSD.

I agree with you on the others though. I'd hate for something unfortunate to happen.

I thought the LSD was purely mechanical when you turn off the DSC?

Mine is purely mechanical clutch type LSD. I'm wondering if that when DSC is on it has something to do with measuring each wheels speed and the cars yaw sensors to determine the cars slip rate and angle to determine when to cut throttle and/or engage a wheels brake.

Very nice.

Yes I am curious too.

[terraphantm]

Sounds like your ZHP is performing better with the m3 DSC settings than the M3 actually does :shifty:

I think the problem in the m3's case is the DME. Just cuts way too much power when the DSC module requests it. Might have to tweak the torque map

Now that I think of it, the CSL software is less aggressive about restricting power. I can switch back to that when I get my airbox

[JupiterBMW]

Hmm sounds like there's less to worry about than I anticipated. Not sure I want to pay for an LSD, but this makes it tempting...

indeed. full M3 swaps can be done for $1000, but for $1900 you can get a 2-clutch LSD from diffsonline. straight swap (and advanced swap - they send you the diff first). it would have to have huge winter weather benefits for it to be worthwhile for me.

On another note:


http://www.bmwtech.ru/pdf/e46/ST034/13%20P1%20Traction%20and%20Stability%20Control%20I nternet.pdf

I'm reading to gain a better understanding.


Modified ADB function (2-wheel drive vehicles equipped with MK60)
The ADB is an automatic differential lock that improves traction. The slipping wheel is
braked by pressure built up in the hydraulic unit. The drive torque can be transferred to the
wheel with the greater traction, which can transmit drive power to the road. This function
takes the place of a limited slip differential.
The MK60 DSC III system incorporates two methods of ADB based on the DSC switch
input to the control unit. With the system “on” the ADB works with engine intervention at
a threshold of below 40kph(24 mph).
Tapping the DSC switch (<2.5 s) increases the slip threshold of the ADB up to
approximately 70 kph (42 mph) for the purpose of increasing traction.
This feature is also helpful for example when rocking a vehicle out of mud or snow.

[PirateZHP]

Cops? As in Po-lice? Nah... just get it done before they get there. If they come up on you afterwards, just tell them that it is time for new tires, and it is hard to keep them from spinning... You are sorry, but all you want to do is get home...

I'm also curious on the M track mode enabled on a non-M. It appears someone made it work on Terra's thread about M-track Mode.

Comparing the NON-M DSC values to the STD M3 and ZCP M3 is an order.

Terra already did the STD to ZCP.

http://www.m3forum.net/m3forum/showpost.php?p=1064868851&postcount=1


If so did you notice a difference in the intervention, even without M-track mode enabled? I ask, because I was comparing the default coding data between a ZCP and non-ZCP M3, and there are quite a few differences - seems to go beyond the differences that are there due to the brakes, steering rack, and M-track mode. In fact, it seems like all of the settings are taken directly from the CSL. If anyone is interested, the settings are in the code boxes below. It's all German (and some cryptic abbreviations too), but maybe you guys can make some sense of what type of values they're changing. First box is the differences only. Second box is default M3. Third box is ZCP

FWIW, When you perform the retrofit coding for the ZCP/CSL brakes on a standard M3, the only thing that changes is "DRUCKMODELL_HINTERACHSE" which translates to "pressure model rear axle", which makes sense considering the larger rear pistons. "LENKWINKELKENNLINIE_2" has to do with the steering angle sensor calibration, which is due to the quicker steering rack.

It's more of a less strict traction control. It lets you slide it more before saying hey, I'm taking over. I'm more curious that if it can be retrofitted to any MK60 system. Chances are I won't even bother with it, as it is usually fully off during track days. I just want to know if it is possible to do and if it is, I probably code it in. :D

I'll probably pull the codes out later in the afternoon.

I don't either. Right now its basically comparing the data of the MK60 of my ZHP, M3 Standard, and M3 ZCP (The data is from terra for the M cars)


There is a fair amount that is different and I am wondering which portions need to be non-m and which can be matched to the ZCP.

Not long at all. Basically I copied n pasted the .TRC file into a google doc and copied the code that Terra posted in the m3 thread. They matched up line for line so it maybe possible!

Maybe you can play around with it Wyatt.


I also forgot to double check if the cluster shows the M track mode symbol or not. I'll do a cluster test when I leave work to double check.



update:

I updated the file in my original post with a new link. It looks like I should keep a fair amount as ZHP. Gearxxx seems to be engine brake? or something similar.

[Crickett]

Derek, you are the man for digging into this! I fully plan to take advantage of your hard work once I get myself an ///M LSD! Bravo!

Update:

My zhp cluster does not have M Track Mode Icon during the cluster self-test. From the faint print, I do not see the icon present. The DSC 2-stage indicator is still a viable option.

https://docs.google.com/spreadsheets/d/1PwZoAJHq47_SZz_zRG4L_Axn8X_VvMdZViXjEZheo1Q/edit?usp=sharing

Results:
The C12 module failed to code the different understeer and oversteer parameters that the ZCP MK60 has enabled. I recieved a fault code4 "coding is faulty" when I tried to enable the parameters.

With help from Kalim, I use NCSdummy find out the parameters were not available in the C12 module DATEN File itself. I browsed other MK60 modules and found that the C06 module is an M3 MK60 with the available parameters I wanted. I grabbed the C06 module data values for the parameter values I wanted and added them to the C12 module. Once the module was updated I proceeded to NCSexpert. I recoded the C12 module with the newly added parameters with no errors/issues from NCSexpert. I opened up DIS to double check for faults/errors on the MK60 and I did not see any errors or faults during a short test.

I did not get to drive the car yet, let alone start it up. However based on the DIS module short test, it seems that the DSC is accepting the new parameters. If these parameters actually make a difference, I will have to find out.

Thank you Kalim for your help! Thank you Terra for the information, and Thank you Wyatt for actually making a thread here that pushed me to look into this. :X

So that keyword is this:

VOLUMENDURCHFLUSSPARA_2 - Hydraulic Control Unit Volumetric Flow Rate Parameters 2

There is 5 values available:
wert_10, 02, 03, 04, 05.

wert_10 options:
!DSC3+!MK60_CI_09,MK60_CI_09+!DROSSEL+!MK60_CI_12

wert_05 options:
(MK60_CI_12,S54B32)+!DROSSEL

the other options all seem to want an S54, is just either !C09 or C09.

Drossel = throttle, but I am not entirely sure what it means for options, not drivebywire? idk.

I wonder if I made a typo because wert_05 requires an S54 in the options. I should be wert_10 based on the options.

[terraphantm]

The comma represents "or", not "and"; so that wert_05 option translates to "(C12 OR S54) AND NOT DROSSEL"

Seems like bmw wants the C12s to be wert_05 for some reason.

Guys, I made some further tweaks to my MK60 module and I LOVE it.

Lately my DSC has been really annoying because when it steps in, it really STEPS in, and STOMPS all over my fun. It just CUTS throttle and it feels like someone jabs the brakes in the middle of my fun time.

So I started comparing my MK60 settings to the M3 specs, and taking a much closer look.

That's when I looked a lot closer at the Oversteer limits and Gear Torque Control settings.

The oversteer limits (UEBERSTEUERN_MUE_0_2 and UEBERSTEUERN_MUE_1_2) settings are pretty straightforward, I just set them to match the M3 values.

Since I don't purposely understeer my car for any reason, I left the understeer settings alone, the ZHP values are fine IMO.

Next I looked closer at the Gear Torque Control values (GEARMOMENTREGLER_MAX_HA_2 and GEARMOMENTREGLER_MIN_HA_2). I created and/or set values on these so they mirrored the M3's MK60's values. I'm not exactly sure what these were going to do, but, I gave it a shot, and I think these directly influence how intrusive the DSC is when it cuts power, because it is sooooo much better.

It became clear to me (I overlooked this before) that the actual values for the "wert" parameters can, and sometimes are, different between MK60 module versions. e.g. a "wert_04" in the MK60 C6 module doesn't have the same actual value as the "wert_04" parameter in the MK60 C13 module. So in some cases I created a "wert" parameter with an M3 value and used that to get the values the same as an M3. Thanks to derbo's thread here for the detail on creating parameters and setting values:

http://www.zhpmafia.com/forums/showthread.php?12642-DIY-M-track-Mode-for-non-M-MK60s

So the net result is that my DSC module is actually very tolerable now. The oversteer limits let me get on the throttle through the turn and allow the rear to start to step out ever so slightly before the DSC gently kicks in and keeps the car on the line. I have to emphasis gently. Because I almost didn't notice it kicking in, there was no CUTTING of the throttle, just a little adjustment that kept the car powering forward, on target. Also, from a dig, the DSC is allowing slightly more wheel spin before kicking in, and it is still cutting power but not nearly has harshly as the stock settings did.

So the only settings I've changed from stock are those relating to my Wavetrac LSD and one-touch-off, and these.

Car feels so good now, do this at your own risk, but I definitely recommend it.
