this thread dis full of awesome, then went to look for an ABS pump and GAWD DANG! 2600$ for a complete kit!
It can be done a lot cheaper than this. Focus your budget on a quality used pump, new pressure sensors, and wheel sensors. Connectors and stuff can be sourced from the junkyard. Grab the yaw sensor while you’re there. The wiring is straightforward, you’ll only be limited by your skills at making/splicing the harness.
I don’t know the current market, but if the MK60 modules are commanding a premium and you’re not rules-limited, checkout pricing on the MK60e5, that might be better, though I don’t know what that module needs in terms of sensors.

The RX8 sumitomo pumps are getting pretty hard to find. I used to see at least one a month on eBay for <$100. Now they're more like $300 if I ever see one at all. Been wanting to buy a spare for my car. I've found a few junkyard ones listed as non-DSC but it always ends up being a Bosch pump when they go check the car.
On the Mk60e5, I saw a FB post a couple days ago from a guy who'd done it and said the speed sensors are much more difficult to get working reliability. He had it working but switched back to regular mk60 because he didn't trust it.

I've been looking at the RX8 non-DSC pump as a far cheaper alternative to the Mk60.
One potential benefit of the RX8 Non-DSC ABS pump, for even the NA/NB's, is that the RX8 appears to also use VR sensors instead of hall sensors like the Mk60. Now the hall sensors should in theory be superior to the VR sensor, but it would make the swap easier. We could potentially use the current tone wheels and Miata ABS sensors.
From what I've read about it the old RX8 race teams that were running standalone ECU's all used the non-DSC pump and it works well. Now I have no idea how it compares to the Mk60, so I'm scared I'll go through a bunch of work to swap it in and it'll absolutely suck donkey dick like the NB2 setup I retrofitted. MaxxECU has a predefined RX8 CAN protocol, which the pump outputs 4 wheel speeds and ABS warning over CAN.

i'm assuming you're using the wheel speed data for traction control. Just a heads up, i found that using the physical inputs had better results than can bus for that purpose. I've tried both with MaxxECU in my car, using the MK60 and e46 protocol. I felt there was some lag with the can bus.

I'm assuming half of us are in that group and i probably talked to the same guy lol.
I just picked up a MK60e5 and i will be giving it a shot soon.
So i picked up an MK60e5 from an e90 m3 the other week, and decided to play around with it on my desk. I hooked up power and the yaw sensor so far, as well as the PT CAN wires to the Kline usb dongle. It is working perfectly with INPA, so the rumors about needing the JBE or a motorsports flash in order to diagnose or bleed the brakes are FALSE.
Also, there is no internal yaw/accel sensor. It has an external one and works just like the e46 one. So the rumors about the abs unit needing to be aligned properly are also FALSE.
The last thing i need to check before i install it are wheel speed sensors. I'm hoping i can use my existing tone rings, but i am unsure at this point. I did confirm that the e46 sensors do not work with it. An open/closed contact on the wheel speed sensor wires does trigger a change/reading of speed in inpa, so it's possible that a standard hall sensor may work. The unknown thing is that the standard oem wheel speed sensors are able to detect direction of rotation, so i don't know how important that is or if it will still be able to do it with a non-stock sensor.
All this activity on the MK60 and its variants really makes me want to grab a couple of junkyard units and open them up… I really want to know how much variation there is in the actual circuit board hardware. I’ve only seen a few pictures at too-low resolution, but it does look like they have some chips that may be proprietary. Or at least they’re custom silk-screened
Amusingly, Continental has a job opening right now that’s very close to what I do now. Unfortunately I’m not fluent in German. And they’d probably prefer if I lived in Europe…
Sadly, too many current projects, too little time…

I got you. These are from an 860.3 mk60e5 from an m3 that I took.
Has anyone successfully retrofitted the Mk60E5? I can find an E92 M3 pump used for around $200 without any effort. Info on the setup seems pretty scarce though. I read that the tire diameter can be modified on them via CAN, but I've also read you need the E92 CAN gateway to communicate with the pump.
It looks like the pressure sensors are integral to the pump and it adds the pressures and IMU to the CAN stream:

a bunch of us are working on it now. I should hopefully have mine installed within a week

I do the same installation MK60e5 ( 860.3) in my race car. wich speed sensor did you use ? Do you use the ABS reluctor ring or you had to change it to the magnetic tone ring ?
