I can confirm that the DSC version of the RX-8 ABS also requires the stock ECU to work as an ABS. I haven't seen any non-DSC RX-8s (but there definitely are non-DSC NCs, which still do require CAN).

I have no personal experience and am just relaying what I've read and been told, but I also know of a V8 swapped RX8 (on a private forum) that just got the non-DSC RX8 module working on his car with no CAN communication. He started with the DSC version that came in his car and couldn't get it to work. Switched to the 04 non-DSC unit and almost instantly reported that the problem was solved and ABS was functioning.

Interesting. Any pictures?
Did you just have the non-abs front spindles so you used those? Or they are necessary / ABS ones won't work?
Also, who's reprogramming your MK60 to the motorsports firmware?
From what I've been reading on the m3 forum, the regular E46 MK60 is programmed for the stock BMW hydraulic pressures, tire diameters, etc. and IIRC also goes in some kind of safety mode (lower thresholds) when CAN data from the ECU is missing. Some people there use rpi emulators to feed the MK60 with data emulating the E46 ECU and other CAN bus modules to make it somewhat happy for standalone installs.
All that is solved with the motorsports firmware (which also gets rid of the DSC stuff, you need the 813.3 or the 817.3 MK60 hardware for reflashes to work) but AFAIK only very few people have that and charge crazy amount of money to do a reflash (because they can since the software never leaked for public use). These same people have flashes prepped not just for BMW for other applications like 997 Porsches (who dump their Bosch units for MK60), etc.

We've got numerous parts cars laying around. The ABS front spindle will not work. It places the sensor basically in contact with the ring. The Non-ABS spindle have to be machined to work.
We have a few contacts on the programming side and we have the 813.3 with the standard program and 817.3 with the ZHP program for testing.
We are working on putting together a kit for the Miata. Probably going to be really track specific though. Don't know many who would want it on a street car.
I have driven this system in other racecars. Very good and very abrupt when it intervenes. It gets in and out of operation very quickly. It's certainly not your Grampa's ABS on his 98 El Dorado.

If you’re using a fault light like this harness: https://www.bimmerworld.com/Brakes/B...IaAjiaEALw_wcB
youll also need the motorsports reflash to get the light to turn off.

Which of the rings were you testing with and was the contact minor or?
The ones you drove - was that with the motorsports flash? Personal impression on how was it while hard trail braking in corners /abs engaged while cornering - better feel than the NB one channel rear?

There are at least 2 or 3 OEM ring type NB front ABS setups - outboard ring (near the studs), inboard rings (near the spindle), IIRC Mazda also changed something with the ring diameter/sensor sometime in 2004 (most likely the ring diameter changed) ...
Which of the rings were you testing with and was the contact minor or?
We are using the inboard rings from a couple of 2000 Miatas that had factory ABS.
It is the race section of the forum so I guess everyone here is interested in a racing application

I just ordered an 813.3 off ebay (off an M3 with 40k miles on it) with the lateral g, pressure sensors and connectors included.
The goal is to install it in the rear right under the car (taking the spot of the OEM fuel filter)
Now, where is the flashing sowtware?

So ... I got a set of non-ABS spindles too. Seems the way the E46 sensors are shaped/oriented, the front-left one will fit the space on the front-right Miata spindle and vice versa. (Assuming the flat side of the sensor housing is the one where the trigger wheel has to be on?)
Are you making new brackets or just hacked the OEM ones? Seems the bracket should be much thinner where the sensor mounts so, it gets close enough to the trigger wheel.
Also, does anyone know if BMW/Ate have published any specs on what the gap between these sensors and the trigger wheel should be?
