Modern ABS for a tracked 240 (Teves MK60 swap)

Since somebody was interested, here's the cut file for the rear tone rings.

Cut out of 3/16" aka 0.188" aka 4.75mm mild steel.

The center hole is a few thou undersize to allow for tolerance when laser cutting, you can probably press it on as-is, or open it up a little with a sanding roll.

I've ordered, what I thought were the correct sensors for the front, but everything keeps coming in too short.

Has anyone done this and can tell me a specific model year car I need the front sensor from?

It is possible I had the wrong sensor in the bag, but I've ordered twice now, neither have fit. Even with the trimming, they are about 3/4 or an inch too short.

Found a better sensor for the rear axles, no longer requires painful carving of the strain relief, etc.

It's a Nissan part (in my case a cheap clone sold under the 'Autex' brand), cross references 479007S025, ALS624, 5S10761, SU12214, 084-4776, 411.482.

EDIT: race-tested this last weekend, works just fine for us with ~1mm clearance to the reluctor.

See this post.
 
I also used the $15 nissan sensors front+rear, and "works in a 240 spindle" is a relative term. I made brackets out of angle aluminum, BUT I think they only fit because I'm using S60R rotors instead of stock 240 parts.
 
I'm running S60R rotors. I just want something I can bolt through the existing hole of the strut tube. Trying to avoid running brackets under the rotors. I was hoping the Nissan sensors you guys were mentioning would just bolt through.

Guess I'll just try ordering some other BMW sensors and be more specific about the year and make sure its from an M3.

Edit- I'm only trying to get a speed signal from the front currently. I'll end up doing something with a tone ring on the diff for the rear. This is just to feed my Maxx/Gauge cluster some speed info/traction control etc.

Why not just run the stock 240 ABS stuff then?
 
Has anyone attempted this setup on an 8.8 axle? I'd love to have ABS in my car, but haven't found any information on the Explorer 8.8. Looks like some of the mustang 8.8s came with individual tone rings, but the axle shafts are different between the two.

Late answer: MK60 does not use VR sensors.

Not to mention that there's only a single rear sensor on a 240 from the factory, and the MK60 expects one per wheel.

On a related topic (but not really useful for the 240), I'm close to releasing a "companion" module for the MK60/MK60E1/MK60E5 that converts VR wheel speed sensors (like the 240/740/940 have) to the signals that these ABS controllers need. I'll make a post once they're available for sale.

Thats pretty awesome!

I am assuming you would still have 2 individual channels in the back to convert a RWD brick?

I know @DrZiplok and I are interested. Will this allow someone to use a toothed ring in front instead of the magnetic rings with a MK60e5?

Yes, you'd still have to do something about the rear, but it would at least let you run the stock sensors/etc in the front.

Yes, it lets you use VR (passive, like the 240 uses) sensors with the MK60 and MK60E5. I built it because my other car is an MR2 Spyder which has perfectly functional VR sensors but a crappy ABS system.

Note that right now this board converts only VR sensors, but I am planning on making a variant later that converts the "plain" MK60 style sensors for use with the MK60E5.

Hall to E5 (or mixed, for folks adapting cars like the 240 with 3ch factory systems) would be super neat. Something like that would have saved me a bunch of time with the Dajiban...
 
Any suggestions on all the fittings? I was going to use 3/16 niccop lines. I guess I need to find a bubble flare tool.

MK60
ABS In and ABS out
Bubble flare
M12
M10

For pressure sensors I found links for these:

I will probably put a wilwood adjuster valve on the rear line between the MC and the ABS
 
Bubble flares are easy. The fittings lack the bellmouth of a double flare fitting, and are easy to find locally here. In a pinch i have ground the end smooth on a double flare nut.

Good to know. I just need to find a tool that does a decent job at it.
