Standalone MK60 Motorsport ABS

The MK60 Standalone ABS system is a 4-channel ABS system capable of standalone operation in a wide variety of cars.

MK60 Standalone ABS Overview

Operating Concepts

The MK60 is unique among off the shelf ABS units (outside of high cost units from Bosch) in its ability to operate in a truly standalone mode. All of its sensor data is managed within the unit and its diagnostics are performed via a dedicated OBD2 port without the need for other gateway modules or the ECU like is the case with other modern systems. The MK60 is able to monitor its own sensors and regulate wheel slip without integrating into a car's existing electronics.

Due to the onboard pumps in the MK60 there is no requirement for a pre-charge pump which are sometimes seen on other ABS systems (such as those on the pre-2003 E46 M3).

3-Channel vs 4-Channel ABS

4-channel ABS systems (like the MK60) regulate all 4 calipers independently from one another compared to earlier 3-channel ABS systems which regulated only the front calipers independently and linked the rears to a single outlet. This is particularly important in cases of trail braking and corner exit where 3-channel systems can causes issues when trying to regulate slip on one rear wheel and disturb both.

Installation Guidelines

The MK60 can be fitted in a wide variety of cars both BMW and otherwise. Depending on your application, some wiring and plumbing is required but with the use of a standalone ABS wiring harness the installation can be streamlined. The key items required for installation are:

  • Wheel speed sensors (one per wheel)

  • Pressure sensors (measuring master cylinder outlet pressures for the front and rear outlets)

  • Yaw/Acceleration sensor

  • Signal to the ABS system that the brake pedal is pressed (this is typically accomplished using whatever controls the brake lights)

  • 12v power

  • Ground

Installation Location


The MK60 uses on-board pumps and does not require a pre-charge pump to boost master cylinder line pressures. As a result the MK60 is very flexible with regards to installation location. It's not uncommon to see these units installed on the passenger side floor or even in the trunk of a race car. This can be advantageous to make room in the engine bay for engine swaps or to simplify wiring or plumbing.

Wheel Speed Sensors: The MK60 uses active wheel speed sensors (which is common on a majority of modern cars. This style sensor helps increase performance, durability and low speed accuracy and do not seem to have the false cycle problem like the passive sensors do. As a result the MK60 can be integrated into almost any car that is or can be fitted with active sensors. To date there's been proven results with BMW, Audi, and Nissan sensors.

Pressure Sensors: Pressure sensor inputs as used by the MK60 to determine pedal input levels and driver intent. They are installed such as to monitor the master cylinder front and rear outlet pressure. They are not required for ABS regulation but provide performance advantages especially in cases when the suspension is being loaded or unloaded under braking.

DSC / Yaw Sensor: The DSC sensor (commonly, but incorrectly called the yaw sensor) is a combination of lateral acceleration and yaw/axial acceleration sensor. Similar to the pressure sensors, this sensor is not required for the ABS to function. However, it is strongly recommended especially in racing applications. Cars not equipped with the DSC sensor are more likely to experience Ice Mode where the wheels lock and ABS regulation stops. This is caused by the ABS computer not being able to distinguish what the chassis is doing (rotating vs going straight) without the input from the DSC sensor. What is "Ice Mode"? Ice mode is part of the ABS software that tries to interpret when the car is on ice and allows the system to lock the wheels which is the best way to stop in a no-traction situation. The ABS sometimes interprets wheel speed conditions during trail braking as the car being in a no-traction situation when it is not provided with DSC sensor data.


The standalone harness has minimal additional wiring required but there are some items that have to be provided by the chassis.

Power: The MK60 requires 3 power inputs. Two (2) 20 Amp inputs for the pump which should be constant when the ignition is on and one (1) 5 Amp input for the module which can be constant with ignition or switched to allow for turning the ABS system on and off. We offer a power harness accessory to aid in installation: MK60 Power Supply Sub Harness

Ground: One ring terminal must be grounded to chassis ground.

Brake Light Switch: The MK60 requires an input when the brake pedal is depressed. The wire that senses this needs to see a chassis ground when pedal is NOT pressed (Normally Closed) and open circuit when the pedal IS pressed. This can be accomplished a variety of ways. The most basic way is to use the brake light voltage to drive a Double Pole Double Throw (DPDT) relay. BMW offers a relay referred to commonly as the "Salmon Relay" (for it's color) that is perfect for this application.

Malfunction Indicator Lamp: The MK60 has a dedicated Malfunction Indicator Lamp (MIL) wire. This light only illuminates when an ABS failure occurs which in standalone mode is limited to wheel speed sensor failures. The MIL light will not provide indication of DSC or pressure sensor failures since those only degrade (but don't disable) ABS regulation.

MIL and Data Acquisition: See the Data Acquisition section below for additional information.

Data Acquisition Integration


The MK60 is capable of providing data to external systems such as the AiM MXL series of data loggers, AiM EVO data loggers, MoTeC, etc. The Motorsport harness can be configured to offer a variety of outputs to suit the application.

Wheel Speeds

The MK60 outputs conditioned digital wheel speed data in both 5v and 12v depending on configuration. 3DM and RHT have developed interface modules that can provide data with either reference voltage. This data can be useful for logging and also for standalone ECU's that provide traction control based on wheel speeds.

Brake Pressures

Using a breakout box 3DM and RHT can provide front and/or rear master cylinder output pressure data to your data logger device. We have developed custom sensor files for AiM use and can provide support for other data loggers as required.

MIL Output

Using a breakout box 3DM and RHT can provide indication of ABS fault/failure to your AiM dash. We have developed custom sensor files for AiM use with this output.

CAN Output

CAN stream output is currently under development.

RACE Map programming

The MK60 in it's base configuration offers exceptional ABS performance and has been proven to work on a wide variety of applications. The MK60 is used extensively in its base configuration on track cars equipped with high performance street tires and race cars running both DOT-R and full non-DOT slick tires.

However, for users looking for professional motorsport level performance and fine tuned mapping the MK60 can be re-mapped with a TEVES/Conti race program. This map is developed around your specific chassis and takes into account parameters such as weight, track width, caliper piston size, etc.

Upgrade Path

Our general recommendation is for users to start with the base MK60 map and see if it fits your application. We can assist with sourcing a "map-able" MK60 so that you have the option to upgrade as desired.

Sourcing the Race Map

3DM and RHT do not perform this remapping service. However, we are happy to connect our clients with a trusted vendor that does. Please email or call if this an upgrade you'd like to discuss.
