Does the C6 EBCM need the ECM for ABS to work?
Hi,
Been doing some research on making a 2009+ C6 ABS EBCM work on a stand alone basis (or as close to it as possible). I found a thread on here where 1badtantrum eliminated the BCM, steering and yaw sensors which disabled active handling and traction control but ABS continued to function. Thread here:
https://www.corvetteforum.com/forums...-race-car.html
However, based on that thread he kept the CAN communications to the ECM. Will the ABS work if the CAN communications to the ECM are eliminated? I have an aftermarket ECM and engine harness.
Thanks for anyone that can provide feedback.
ETA: for a 2009+ that uses the Bosch unit with active sensors.

It looks like the stop lamp switch signal goes directly to the ECM and then through can data from the ECM to the ABS module. Thats one thing I see so far, maybe someone else can add more. Would rather do a BOSCH MOTORSPORT ABS. It would use the same 09+ wheel bearings. Price on those Bosch systems went down to around $7000.

Id recommend the E46 ABS system, if cost is a concern. Its an active system much like the Bosch, but at a fraction of the cost. It is obviously NOT the bosch race system, but still a performance ABS.
We installed a Motec M130 into a C5 with patchy stock ABS, and its currently getting the BMW system. Will update more as we know. It was slated for a used M4 system that fell through, then an M5 system, but ultimately settled on the BMW system.
Keep in mind if you use the Bosch system and need to feed the ECU digital wheel speed signals, youll need the Bosch Motorsport open collector signal splitter.

Is the Teves system better than the C5 setup?
Will the C5 wheel speed signal work with the Teves, or does it need to be calibrated?

The bmw/Teves system uses active sensors like the c7 and later 09+ C6.

I guess the real question is why us it if the C5 system is good enough?
Have you raced with the Teves system? Is the balance ok?

I don't want to speak for GSpeed but when I looked into it the advantage of the bmw system was it was proven to work on the track and it is a stand alone, self contained unit.

All of the cars we have used it with are race cars. We have a stock C5 getting one now, but its not stock brakes.
Thats correct. If you buy the early E46 pumps with the Eprom you can purchase a better ABS map, more geared towards race tires.

Do you plan on selling this as a package for the guys that don’t want to spend 7k for the m4 system. Personally it would be worth it to me in the 3k range. I checked out the parts and they can be located for about 2200, that is including a stand-alone harness from turner BMW. What do you think?

once the system is tested, we will consider it. Vorshlag has already done this, let me see if they want to add anything.

So you can modify/flash different maps for abs function into the E46 unit?
