Just a bit more info for anyone doing this swap, I bought this cable to plug into the OBD port of the BMW unit and it works great, cost me about $16 when I bought it last year, came with the required software. BMW OBD Diagnostic Tool
Allows you to properly bleed the system, test the brake application of each wheel, check wheel speed sensor outputs etc.
If you have an AIM dash you can also connect the CAN output from the unit to the dash and receive wheel speeds, fault indication plus more I forget.
I'm also running a Haltech elite 1500 ECU and I've got the individual digital wheel speed outputs from the BMW unit feeding into that, this allows me to use the inputs for vehicle speed, traction control, launch control and also the ability to log individual wheel speeds.
Does anyone have a link to this software? The link in the box is dead and google returns stuff I'm pretty sure have me a virus just looking at them
Ran it for the first time, worked flawlessly and a pretty damn nice upgrade. Rear sometimes has the feeling of being nervous on heavy straight line braking, but the ABS sorts it right out. You feel the back wanting to walk a bit but it doesn't actually go anywhere. Doesn't do it all with some lateral g component.
I have an idea for setting the ZCP/CSL parameters, just need to figure out how to get NCSExpert to connect since I can't just read the ZCS values from the other modules.
i ran mine on the track for the first time this weekend and i agree with everything you said. It does get a little squirrely in the rear in straight line braking, especially if i jump a curb with the ABS activated, but it doesn't really go anywhere. and then without lifting i went directly into trailbraking and it was perfectly fine. I contributed it to running a bit more antisquat than what most people probably run, but hard to say. overall, i love it and i improved my personal best by 4 seconds, mostly because of trusting the car to stop.
Circling back here. Took a bit of foot work to find the right sensor that I could adapt into Mr2s front hubs. I spoke with Doug and confirmed my suspicions. I ordered about a dozen different sensors and finally the one that worked best was a Subaru Forester abs sensor
Quick question, has anyone gotten the 4 digital speed outputs to show up in their standalone? I'm messing with megasquirt if that matters. I've not been able to correlate the 4 outputs on any wiring diagrams other than the pdf we're using here. Do they need a 5v pull up?
I've not tried it yet but getting all 4 in my setup is going to mean installing a microsquirt I/O expander so I want to be sure before I spend the
Edit: To add, also does anyone have a suggested hand held OBD2 module to trigger bleeding? still fighting this dongle setup and I can already see where bleeding would be much easier with a handheld.

I got the 4 digital speed outputs to show up on an arduino, so it should work on megasquirt. You will need a 5v pull up.
I also had issues with the dongle/INPA, the version that came with my dongle did not work and I had my OBD plug wired slightly wrong. I can send you the INPA install files I used if you are interested.

i posted how to to get the speed outputs working in megasquirt. i also used the microsquirt io expander and it works decent. I do suspect there is some lag due to can bus, but it works "good enough" for traction control. here's the post: https://www.miataturbo.net/suspensio...4/#post1610543
Thanks for the input guys, TC is next on my list to get working.
Figured out the key to the inpa dongle is it has to be set to com 1 or no dice. Also picked up a foxfire hand held which is handy.
First event under my belt........and who would have thunk it, but the hand of god is German. Holy **** ***** is this good, pretty much transformed braking for me. Obviously you can just jump on the binders and get to threshold braking much quicker and consistently, that part I expected. What I didn't expect was how well trail braking worked with this system, the mk60 will allow the car to rotate to a certain vector and then hold it there. You could feel the pedal push back once you got to the calibration angle. Just wild to experience. It was key to getting this pig around the long sweepers at NCM. Also noticed where I would have pad knock back after a few corners without braking that once the abs kicked in the pedal would rise back to it's normal height which is cool.
I'm definitely going to try the CS calibration and see how I like it, but overall this has been one of the most satisfying changes to the car next to the LS itself.
Here's some video, first weekend at NCM and my AR1s were heat cycled out, so lap times aren't what they should be but you get the idea of what the abs is doing.
A word of warning though, it IS possible to provoke it into ice mode. I highly recommend getting a couple of brake pressure sensors, logging pressure both before and after the ABS unit, and then using that train yourself how to get pressure up to the ABS threshold quickly without going too far over it.

Thanks for the advice, I was being as aggressive as I felt I could be without upsetting the car. I'll be sure to expirment in safe corners when I have the chance, none of those at NCM 😬

by ice mode, you mean where the brakes lock up, or the brakes just say **** you and barely do anything? If it's the latter, i agree, i've had it happen a few times in autocross. However, i have never had it just lock up the tires.

The latter. You push on the pedal and it seems like nothing is happening because the ABS is taking most of the pressure away from the front wheels.

ok glad i'm not the only one. hasn't happened on the track yet fortunately, but i have definitely blown a corner or three in autocross in extreme circumstances. i was wondering about pressure bias being part of the issue since i haven't checked that at all. also wonder if getting it "tuned" would help with that.
Hi guys, So I have taken the plunge and have a mk60 and associated Parts on the way. Its a 818.3 unit so wont send out CAN messages without receiving some CAN messages. I really need the wheel speed for the traction control.
Just a background the electronics on the car are Syvecs (life racing) ECU, PDU, CAN keypad, Plex Dash and a HTG transmission controller for the 7 speed DCT gearbox. I have Syvecs available to do any custom coding but I really could do with knowing exactly what's required to get the MK60 talking. Syvecs Have experience with the E46 M3 and I actually have 1 of their plug and play kits on my own turbo E46 M3 but the difference is that the MX5 wont have the e46 dash or steering angle sensor that their kit would usually see.
So what i have found so far from this thread is: Mk60 sends a RTR. Message looking for a handshake on 0x610 RCP sends out last 7 digits of the vin that is already stored in the mk60 on 0x610 Handshake complete Then the mk60 needs to see the generic steering angle and ECU data on channels 0x316,0x329, 0x613 and 0x615 After this is complete the abs is happy and will stream out the wheelspeeds (and some units the brake pressure) to the canbus network on channels 0x1F0 and 0x1F8
I Sent this to Syvecs and they said that the e46 m3 does not have a 0x610 can message on the car bus and provided the attached image of a capture of the OEM bus.
If anyone could help it would be much appreciated.
has anyone tinkered with later model stuff? specifically the mk60e5?
I picked up one of the flashable units for a future project while they are still cheap / unknown. It is my understanding that you also need to have the gateway module to communicate with the e90 m3 abs unit. 860.3 and 870.3 are the units.

i can't answer that at the moment, but i will be diving into it in the next few weeks with MaxxECU when i make the change from Megasquirt, so maybe we can help eachother. I'm currently using the 0-5v outputs from the MK60 for wheel speeds for traction control and it works fine, but CAN bus just seems more logical. I'll also be using a BMW DCT, but MaxxECU controls it so i won't be using the HTG
