Also, define ice mode. Full wheel lock or hard pedal and no stoppy stoppy? it went to firm pedal with no stoppy stoppy. Worth noting, it has performed flawlessly for a few races and some street driving. This instance was pretty severe braking at the end of a straight away and my tires were pretty heat cycled out. |
Well, I don't like the sound of that. I experienced it with the stock NB2 ABS, it ended in a very expensive day and the death of my confidence in braking on track in higher risk areas.
Have you asked Doug Wardell about it? I'd be curious to hear what he says. |

I have not (mainly because I don’t know who that is lol)

I had Doug from 3DM wire in a wheel speed control module for me to utilize the wheel speed sensors to be used to TC. Im sure it would be fairly simple to replicate.

I am going to add a couple more high speed inputs and get the other two wheel speed sensors working before the next race. |
Is there a way to get the ABS to allow more rotation under trail braking without the race reflash?

So it turns out setting the CSL parameters is pretty easy. It took me a couple of days to figure it out since the steps aren't anywhere online for those of us running the MK60 in standalone and figuring out how to get NCS Expert to connect to the MK60 without being able to pull data from the other modules was a bit of a journey.
Alright, so since I've now walked two people through doing this today I'm going to update the directions 1. Read the VIN from the unit in INPA by connecting to it and clicking the Ident button. The VIN will be at the bottom, if you are curious to see the car your unit came out of then change the leading WBA to WBS and Google it. I have no idea why the vin stored is different than the chassis vin. 2. Open NCS Expert, File -> Load Profile -> Revtor's -> VIN/ZCS/FA -> Enter ZCS -> Choose E46 -> Paste VIN, click Calculate checksum checkbox, OK, press Cancel. Look at last letter in the FG line, this is the checksum for your VIN, you will need it for the next step. 3. Create a file called m3.ssd with the following in it: M E46_CODIERSCHL ALL A 001 WBABR93433PK02711N E46_#0303*BR93 \ $210$249$354$388$399$431$441$459$464$473$481$494$5 02$520$521 \ $522$534$550$640$645$650$661$674$692$710$785$845$8 53$876$925$992 7. Replace the VIN on line 2 with your VIN with checksum. Example: MK60 vin - WBABR93433PK02711, VIN from NCSExpert FG Line WBABR93433PK02711N 8. Replace 0303 on line 2 with your YYMM of production, if you can find it, otherwise leave it alone. 9. Replace the BR93 on line 2 with your chassis type. If you look at your VIN it is the 4 letters/numbers after the WBA. A BR93 is a convertible, a BL93 is a coupe. 11. Go back to NCS Expert, click Open file, open the m3.ssd file, click ZCS/FA.f file, click OK, click Back 12. Plug your computer into ABS 13. Click Process ECU, click the MK60 line, click OK, click Read ECU 14. Open NCS Dummy 15. Open the NETTODAT.TRC file you read from the ECU, it should be C:\NCSEXPER\WORK\NETTODAT.TRC 16. Set the following options in NCSExpert BAUART_MK60 - CSL (I don't know if these matter, they might be DSC only settings but I set them anyway) UEBERSTUERNM_MUE_1_2 - wert_11 UNTERSTEUERN_MUE_1_2 - wert_03 UNTERSTEURSCHWELLE_2 - wert_04 17. Click Export FSW/PSW then click Export FSW_PSW.MAN 18. Go back to NCS Expert, click Change job, click SG_CODIEREN, click OK 19. Click execute Job Done, I recalibrated all of the sensors just to be sure. It seems like there are some other settings in here that could allow tweaking for specific chassis differences but I have no idea what is going on so I left everything else alone. DRUCKMODELL_HINTERACHSE is changed to determine M3 vs M3 CSL rear calipers (larger pistons), I left it alone. I verified that all of the things I set were changed by reading back the MK60, but I haven't been out with it yet so YMMV and all, I'll report back once I test it next weekend. |

When you say setting the CSL parameters, do you mean "upgrading" a standard M3 ABS unit to the CSL programming? I just want to clarify that you didn't find a way to put in your own values, which would be monumental. |

Thank you for the detailed notes, this is great work. I don't have all the software in front of me right now, but I may look into this more at a later date.

I just want to clarify that you didn't find a way to put in your own values, which would be monumental. There are some parameters that can be changed like hydraulic volumetric flow rate, dynamic brake control min release pressure, etc but I suspect that they are not related to strictly ABS and it is not what what we're looking for, so no, nothing important and the actual answer for doing what you're asking is still: This place is $1100 Race ABS MK60 Flashing and ECU Standalone - Race and Trackday Parts This guy in the UK also does it, but he wants $1700. https://www.facebook.com/bmwm3motorsport/ I'm currently looking for another 813.3 unit to send to the former place just so I can try it out for fun. If anyone knows of a place in the US please let us know, I'd hoped that some eastern european based forum would have a dump but I haven't found anything yet. |
Keisler front spindles
Attempting mk60 on keisler knuckle setup
I removed caps. And torched the winding out of the cap. This seamed like the best way to remove it all without ruining the cap. I’ll likely weld the hole shut and add a sensor where I need it and weld a nut to the cap to secure the sensor https://cimg9.ibsrv.net/gimg/www.mia...03d412ea8.jpeg https://cimg0.ibsrv.net/gimg/www.mia...195460209.jpeg |
Hey guys been quietly following along and finally gathering up the necessary parts to jump into the deep end with you all. I really want to be able to gather up the wheel speeds via can bus to better integrate with my megasquirt, I use traction control but with only 2 wheel speeds and it has some shortcomings. Getting all 4 wheel speeds into the unit is a bit finicky in that the MS3x I use doesn't have 4 high speed digital inputs and ideally I'd like to leave the flex input open for flex fuel in the future.
As it's been mentioned here and elsewhere the MK60 without the motorsports calibration will not stream can bus data without a hand shake. There is this option, although it's expensive enough it has me contemplating a microsquirt as an I/O expander instead. CAN Emulator for MK60 I posted up the question on a Racecapture discord channel since the racecapture units can do Lua scripting via canbus and I thought getting the 4 wheel speeds and possibly brake pressure would interest that crowd. Sure enough a very smart individual spoke up and it looks like it's going to possible to do with their unit which I already have but also the script is being discussed and could be used in other units possibly even a megasquirt. I'll be honest a lot of this is over my head but I wanted to get the info captured and posted here in case anyone could use it. I apologize for the funky copy and paste but wanted to get this documented here for everyone's use. November 13, 2021 November 14, 2021

i'm in the same boat as you. i'm out of high speed inputs and traction control sucks with only 2 channels in MS3. i bought a cheap industrial plc that does canbus to see if i could get it working with MS3 so i could use those inputs instead, but haven't gotten far with it. This seems like a much better option (if i can somehow get smart enough to follow along). thank you for posting this, keep us updated on how it works and i'll do the same if i get anywhere with it.

just an update on my ice mode. I found i had a very bad rear wheel bearing that allowed the tone ring to move away from the wheel speed sensor, and probably far enough to cause a loss of signal. I'm hoping this is all it was, but i'm unsure if one wheel "locking up" would cause it to go into ice mode.

I haven't tested my MK60 at tracks that I usually end up lifting a wheel while hard on the brakes (read: catching a curb) yet, but that was a recipe for 'ice mode' 100% of the time with my stock NB2 ABS.

I can't keep track, do either of you have the yaw sensor working? And do you have an active error for the pressure imbalance? I'm trying to narrow down on what helps avoid the situation and deicide if I'm going to maintain the Miata brake balance or recreate the BMW brake balance to avoid the error code that doesn't seem to affect anything.
