MK20 -> MK60 Swap

[Bry5on]

Absolutely! I'd love to open-source MK60 flashing.



I would have, but I pulled the mk60 wiring out of that main harness about a year ago with the original intent to use it in my Honda race car. Since then, I changed my mind and decided to use a Honda S2000 ABS system instead; it was far easier to get working and very similar in performance to the mk60. And I have cannibalized what's left of that sedan harness for other projects. I suppose I could have gotten another harness but he had already cut and removed a bunch of wire from his harness (cut as far back as he could without removing the dash/hvac), so it just seemed like that was the right play.

But for anyone else, there are very few differences between the M3 and non-M harnesses for the most part, and it's a much cheaper option for obtaining a main harness if you need one for this conversion.

I think it’s just the TPMS button (and m-track button for CSL/ZCP) that differs. And if you run the wire for TPMS button the non-m MK60 handles the input for that too.

Happy to donate an MK60 to this project

Hell yeah. Let's see how far it's feasible to get using non-destructive methods (i.e. trying to disassemble a FW dump from one of the official BMW tools), but I'll definitely take you up on that if/when it becomes unfeasible to continue down that path.

Figuring out how to reprogram ABS would be badass!

I would check racing sanctioning body rules which might change some things. For example the E1 is legal in NASA ST/TT4 which is where a lot of BMW E chassis cars land for classing. Might make the endeavor more worthwhile.

I suspect the amount of effort needed to go from zero to "one MK60 HW version flashable" is orders of magnitude larger than the amount of effort needed to extend the flash tool to work with all the MK60 versions. So, highly likely that once one is figured out, all the others will be modifiable as well.

Even if you want to use it with a bench harness setup, no sweat, just let me know.

I volunteer karter16!

Hahaha I honestly would love to get stuck into this, but I already have too many projects on the go I will very excitedly follow along though if you do decide to have a go at this!

If there's a path to reflashing the MK60, I don't think it's over OBDII. I suspect they left CCP/XCP open based on what I have heard through the grapevine and know of people doing on other DSC modules, and that's probably a path forward.

Very cool! That sounds like a pretty great setup for a street/track car. Wonder if it can be taken further with a ZCP/CSL module that has the extra button input. Something like stock modes on by default. DSC off, street ABS with a press of the M track mode button and DSC off + race ABS with a press of the switch center button.

Maybe it's time to revisit the disassembly of these modules (including the Z4/E9x/E1/E5/etc.). The data processing robots are getting pretty good these days, I bet this is a task well suited for their skillset.

Well, I don't know about all the stuff that you mentioned, but there are certainly some things possible.

I run the MK ABS software on my m3 and it works great on track.

Since I use an ECU master engine control, standard DSC is not working for me anyways, but ECU master has its own racing TC, so I'm fine with that. MK offers a standalone ABS unit, it's also a MK60 block, but from a non-m E92 afaik. Advantage is that it broadcasts more data on the can strEam than the E46 blocks. It has two changeables: a soft street like interference or a harder race mode and a soft kill switch allowing to drive without abs. Disadvantage is you lose the features that come with the integrated units such as DSC.
