You may want to be strategic about how you make this setting,
for example, making it the best compromise position for all
conditions.
Testing
After assembling the system components, you need to carry out a function test
before the first test drive. This test will ensure all components (electrical and hy‐
draulic) were assembled correctly and are functioning properly. The vehicle
should be placed on four jack stands or on a hoist so that all four wheels can be
moved freely. If there is no other option, you can lift and test each wheel sepa‐
rately. You will need an assistant to help you check the hydraulic allocation of the
wheels.
Step 1: Testing the communication with the ABS M4 ECU
See section Laptop Communication
Step 2: Testing the wheel speed allocations
With the vehicle jacked up, spin individually all four wheels clockwise and check
for the proper front/back, left/right allocation. When you spin each wheel, the
corresponding position should show a value in the RaceABS software under the
"Testing" tab:
