ABS control unit coding - custom configuration?

When designing an ABS (Anti-lock Braking System), there are essentially three different types of control strategies.

1. Select Low Rule (SLR):
The wheel with the lower braking torque determines the braking torque for the entire axle.
Advantage: The car doesn't distort the image. No steering forces.
Disadvantage: In the worst-case scenario, the braking distance can be significantly extended.

2. Individual Select Rule (IR):
Each wheel is tested on the block brake.
Advantage: Maximum braking performance.
Disadvantage: The car can become unstable and even spin out of control. Steering forces are generated when the steering knuckle radius is not neutral.

3. Modified Individual Select (MIR) Regulation:
The braking process starts with SLR and gradually transitions to IR. The driver is given time to react to the steering forces, to steer in the opposite direction, and, if necessary, to ease off the brakes slightly.


Older vehicles typically have an SLR (Steering Limit Reducer) on the front axle and an IR (Integrated Rear) on the rear axle.


Last weekend, I attended a driver training course. The task was to perform a braking maneuver on a surface where the right wheels were on a completely smooth road surface, while the left wheels had very good grip.
I couldn't get the car to stop at all during the entire distance. I didn't feel any braking power! The car remained completely neutral. I suspect a purely mechanical self-locking differential on the front axle, and possibly also on the rear axle.

With the ignition off, I managed to bring the car to a stop halfway by applying a controlled braking force. I had to fight for it and brake carefully, but at least I managed to stop.

Therefore, my question is:

Are there any parameters that allow me to adjust the individual contribution of each wheel? Of course, I don't want 100% brake pressure on the left side if there's black ice on the right, but I don't enjoy this overly simplistic interpretation.
I can steer and I can brake, but I would like to have more braking power on the side that has grip. I consider the current ABS design to be equivalent to a final warning!


Thank you very much!



My vehicle:
Seat Ibiza 6K.
Engine AFN.
Manufactured in 1998.
15' standard brake system (280mm, 4x100 bolt pattern).

Which ABS system do you have?

Is this Mark version 0.4, or already Mark version 20?

There's nothing we can do about it based on the diagnosis.
