Racing ABS Wiring Harness - (NO LONGER AVAILABLE)

Our custom ABS harness allows the Ate Mk 6.0 ABS system from a 2003-2006 BMW E46 M3 Competition Package (ZCP) to run as a “stand alone system” and potentially be installed in ANY CAR, not just a BMW. Most of our customers will use this system to replace a 3-channel ABS system which is inadequate on the racetrack. Our harness will allow the E46 M3’s ABS to work without needing any of the factory wiring harness or dash cluster - it's stand-alone! The E46 M3’s ABS system is a four-channel high performance system which applies ABS to each wheel rather than a three-channel system like on a BMW E36 that only sends one signal to the rear (and two to the front). The Ate Mk 6 system is currently one of the best ABS systems on the planet. We have used this setup on all of our Grand-Am BMWs with tremendous success. This is also the “hot setup” for Porsche 997 track cars because the standard chassis electronics (PASM) has shortcomings on the racetrack.

Our harness also incorporates an output plug which allows the user to connect to the ABS control unit with a laptop. This allows electronic brake bleeding and diagnostics. A toggle switch allows you to turn the system on or off (cycling the switch resets the system) and a LED warns of a system failure. The signal to the warning LED can also be incorporated into a racing dash display. Software for diagnostics and the cable are included. The ABS software is not programmable but has proven to work very well on a variety of cars.

A Motorsport ABS control unit is also available which optimizes the ABS for racing tires whereas the standard unit is mapped for street tires. For most drivers the standard control unit is sufficient as it's a huge improvement over the system it's replacing. The traction and stability settings of the Motorsport programming are much higher compared to the stock unit which allows the driver to make full use of the race tires with maximum braking generated in any condition. It will also generate additional data that the standard unit does not provide. This Motorsport control unit can be added to any 2003-2006 E46 M3 for an instant ABS upgrade. The Motorsport control unit will also automatically adjust for different wheel sizes and any ABS ring gear/tooth count so it is required for all non-BMW applications.

The harness requires several factory BMW components: ABS ECU/Pump, yaw rate sensor, ABS pressure sensors (x 2), and wheel speed sensors (x 4). We have packaged new parts together to make it easy or you can source your own from a 2003-2006 E46 M3 ZCP/CSL.
