M-Track Mode

Let me guess, it's a SMG?

2004 SMG yes.

Luckily our cluster had the M track symbol LED already.

Anyone know how the stock (non-ZCP) bias compares to the bias with the 996 conversion?

Jesse

looks like the zcp bias is nearly the same as the 996 conversion according to this table:
https://thebuildjournal.com/tech-gui...-chart-e46-m3/

will add this mod next

stock 1:54.1 – 60.6%F 39.4%R
zcp 1:38.1 – 58 %F 42 %R
996 1:39.1 – 58.1%F 41.9%R

Awesome. Just coded this now using NCS Expert version 4. Luckily our cluster had the M track symbol LED already.

This was actually my first time using NCS Expert, I understood the fundamentals but navigating the menus was a little confusing. The instructions written up were great but don't match the wording in version 4. For those of you endeavoring to go down this path, all the instructions are easily mapped to version 4 except the stage where it asks you to press "SG/SGET", in NCS Expert version 4 this the "Change ECU" button.

That's what i figured. Is the CSL rack and brakes the same as the ZCP?

I thought the CSL had a different king pin. Would this affect the DSC coding in any way?

They are, but you can code those independently, so it doesn’t matter.

Kingpin doesn’t matter.

The description on 3dm reads exactly like what M Track mode enablement does. Had an E60 M5 that had this mode standard, and when I got my E46 M3 I hated how much the standard system intervened. It was one of the first things I programmed as soon as someone made the instructions to do it, and it matches very closely with how it worked in the M5...you can get a little more drift on the rear end going without getting completely out of hand. U-turns under power are a lot more interesting.

Is this coding the same as "CSL MK60 Parameter" being sold by 3dm?

Depends on the bias of your bbk. IIRC the ZCP brakes are slightly more rear biased than stock, so if your bbk is more rear biased than stock (and I’m remembering correctly about ZCP) then yes. Otherwise no.

e.g. My brembos are slightly more front biased than stock, but my car is slightly front heavy shifting the bias rearward, so the non ZCP setting should be pretty perfect for my car.

A properly set up bbk shouldn’t feel “stronger”.

If I have my car tuned and will perform this M-track coding will it mess up with my tune uploaded into the DME?

Nothing related to this touches the DME tune.

Do we know how much slip angle MTM allows?

Not enough that you'll be happy with it on track. It's amazing for street use... and not useful for track use.

Sine doing my SMG conversion a year ago I have somewhat forgot how to code.. But I do remember after doing the conversion I got all code happy and went through the thread on the old M3 forum and basically did everything on there (I LOVE the euro flashers for some reason)... I remember this being as easy as the rest obviously and found it to be my absolute favorite option I have turned on. I am an early-ish 03 as well, actually have a build date of 3/17/03 so I believe one of the very first facelift cars and it works flawlessly. I also use it as my preferred mode for normal driving

My only slight disappointment with M-track mode is that you can't use the fastest shifting parameters in SMG unless the DSG is fully disengaged.

What are you...a masochist? With the CSL software, every shift in S5/S6 feels like it would tear the RACP completely out of the car. I have to modulate the throttle even in S5 to not feel like it's banging the entire drivetrain to pieces. Maybe if you didn't also have the CSL software, in which case non-CSL S5 = CSL S3 and that would make more sense. I had an E60 M5 years ago, and at least between the engine power and the SMG3, it would break the tires loose in the 1-2 and 2-3 shifts in S6 at full power and give some relief to the drivetrain. Sometimes I wonder if the intertia fix puts a little too much clamping power down and should allow for just a little clutch slur, at the expense of clutch life but saving the drivetrain and RACP.
