Definitely not at the moment. So an MK60 with reflash as a kit costs how much including hardware?

 

Depends on where you buy it. If you find a car being parted out, if you get one from a vendor, there are a few people selling them. Find a local person parting out a car. Shop around, there are a few places offering flashes and units and harnesses. Nobody offers a full FD kit, you need to source chassis specific bits yourself.

I thought about offering a kit, but I don't want to be responsible for people's brake systems. FYI everyone: you're doing this at your own risk, nobody here will take any responsibility for your results with this. Modifying brakes should only be done by a professional.

There's a link early on with someone offering wheel sensor adaptors for the MK60. But unless you're restricted by rules, MK60E5 will do pretty much the same thing for less money now that E46 M3s are very valuable on their own, and NASA rules requiring MK60 for some classes

 

I want to say thanks for your help. I still find it amazing that this forum is my main source of knowledge, maybe because I'm old school. I do follow those FB pages mentioned. My current situation is that I am building the car and wasn't thinking about ABS until I came across the MK60. Things are a bit more complicated for me as I live on a small island in the Mediterranean and sourcing stuff is a bit difficult or much more expensive than if I was in the US or a big country on mainland Europe. Notwithstanding I am here to learn and appreciate all your input to help me make an informed decision when I decide to buy.

 

Happy to help, that's what we are all here for.

You can probably find the MK60E5 ABS in Malta from a crashed car, the mag rings you'll need to buy. The wiring is actually surprisingly simple, but you need to used the right twisted pairs so you get a clean signal. You probably deal with crazy import taxes as well, so doing the wiring yourself is a good way to cut down on the cost. Unless it's a very serious race car, you'll probably be fine with the OEM ABS programming, lots of very fast cars out there without a flash.

 

I would love the drawing for this! Working on mk60e5 in my 93 currently!

 

Living in Europe the BMW e8x and e9x ABS units are plentiful. However I don't quite understand how to differentiate between the MK60e1 and e5 units? When I look at the local classifieds for e8x and e9x ABS units there is literally 50+ units for sale at every given moment...but how do do I know exactly which one is the e5 unit?

I did find this post on the Facebook MK60e5 and MK60 ABS retrofit group

E92 came with mk60e1 or mk60e5 or bosch DSC8 (never mk60).
E92 4 cylinder mk60e1
E92 6/8 cylinder mk60e5
E92 4wd bosch dsc8
You can tell by looking at the units.
Mk60e1 control unit has rectangular top
Mk60e5 control unit has 4 recesses to access the fasteners that hold it to the hydraulic block.
Bosch says Bosch on it.

Mk60e1 (note rectangular top):



Mk60e5 lid (note the recesses):



So is this info correct?

 

Hey Spalato. That looks to be correct. IIRC the difference between the MK60E1 and E5 are the number of internal pressure sensors it has. I have one (an E5) that came out of an E90 M3 and it looks exactly like and might have the same part number as the one in your second photo. (I can check if you would like!)

Here is a list of part numbers and software versions that I found on the fb group a while back. Hope it can be of some help. https://docs.google.com/spreadsheets...gid=1017005231

 

Hey,

Thanks for the google docs link, I sent a request for sharing it.

yeah if you can check the part number that would be great.

 

The one in the second photo is just what I found in the FB post on how to visually differentiate the two units. So far all the units I found for sale here locally are the non M3 units. But I believe even the non M3 MK60e5 units will be soo much better on the FD compared to our OEM units.

 

Hey Spalato, I just changed the access conditions so you (and everyone with the link) should be able to access it. Let me know if it isn’t working.

I took a picture of the ABS unit. It is an 860.3.

 

Nice! Thanks dude.

 

mk60 with CSL flash. Going to make sure it reports wheel speed before I change the brake lines.

 

....you can?

are the connectors the same? more or less the same length?

I made a post asking about alternative sensors and didn't get any replies.

 

I cannot confirm this. My vendor initially said it was possible but I ended up going with E46 sensors since adapters were avail able for both.

 

Oh, ok. Thanks. I am going to assume he meant you could use it for the upgraded ABS system.

The FD stock ABS sensor looks different and uses a totally different connector. Explains why the FD sensors cost more than twice as much…

 

Just to jump into this thread... I was in an FD chat on Facebook and someone had stated there was need for a wiring harness to be built for this system. I'd be interested in tackling the harness if people really were using these and there were sufficient diagrams needed for construction.

 

There's a few people who already make harnesses. Douglas Wardell from RHT Motorsport already offers a full system, just tell him what lengths you need and other specifics.

Tulay offers the full plugs and pins kit, just buy some regular wires and some twisted pair wiring, this is the best for a custom install, you can get the actual lengths you need vs trying to measure it.

There are a ton of wiring diagrams out there that cover the MK60 and MK60E5. Just find one and make it.


After using a pre-built harness from RHT, I would definitely opt to make my own in the future to get the lengths right. It's a really simple harness.

 

I am working on a similar project for my FD. Would you still be able to share the file? Looks like you mounted the mk60 in the drivers side. Is that correct? Thanks.

Correct. PM me your email and I'll send you the file.

 

So I've been contemplating putting ABS back in my FD as a winter hibernation project. Going back to the Mazda OEM ABS is a non-starter because some of the space occupied by the pump is already being used by my OMP pre-mix tank and a small catch can, but it looks like I still have enough room to squeeze in the MK60E5 unit. While doing some online research, I stumbled into this thing: https://happycactusgarage.com/produc...oXDYVr2UbGxSwl

Apparently, this $350 electronic box does the signal conditioning needed to make the existing VR wheel speed sensors on the FD usable with the MK60 / MK60E5 stand alone ABS. So if you have working OEM FD sensors, it would save you the step of retrofitting some other compatible wheel speed sensor into the FD chassis. Has anyone used this thing on an FD MK60 install?

Also, where are you guys sourcing all the key components to do your MK60E5 stand alone ABS retrofits?

 

The only issue is, the FD is a three channel car, and MK60 is four channel. It may be worthwhile still to retrofit the forth channel and retain the factory sensors, but by the time you've bought the converter and done the new lines, the change to E46 sensors isn't a big deal. There are adapters for F/R out there.

The value I see to it in the future is that I'm creating spindles in which the RX8 hubs could be used, and they have a self contained sensor/wheel so being able to use that signal might be a great thing.

 

Very nice find Pete! that device looks like it would be pretty easy to adapt and by jumping some wires back together at the OEM ABS control module between O-01 and to O-02 for FL, RL, RR, Fault light, and Brake light signal. Since O-02 is limited to 7 direct wires the FR signal would need to be picked up at the module. What would you suggest doing with the shield wire (8) for the cactus module?
Switched power for the cactus module could come through W/R at x-02 if it was wired over to B/LG (Switch power for EGI and fuel pump relay)at the fuse/relay box on the left strut tower.

 

Since all of the OEM wheel speed sensors are wired to O-01 and the shields for each sensor (Gy wire, (R) harness) terminate at the same ground point #13 as the OEM ABS computer, if you physically install the cactus module where the OEM ABS computer was, you can just jumper its shield ground terminal to the same #13 ground point.

 

I grabbed the Happy Cactus box a while back. It inverts the brake pedal signal as well to make life easier. Was gonna use it on another car.

Going to get back into this soon. New engine is being stacked this week, will do the run-in then tackle ABS again. 8HP swap has been taking most of my concentration along with the R3 / UC-10 etc. Big victim of project creep…
