Fixed it for you
Thanks!

This is why I wanted to have the ability to analyze when the ABS kicks in using AIM. On the PT6 protocol the 10hz limitation was not fast enough.

AIM increased the sampling rate max to 25 and 50hz.

If you are using AIM and the PT6 CAN bus, I recommend updating your config profile to the latest PT6 (2.00.06) and increase the sampling rate to 25Hz.

using the deriv(brake press specific wheel) watch the brake pressure fluctuate while the BRAKE PRESS is INCREASING.

BRAKE PRESS is what you do
BRSKE PRESS individual wheel is what the car is doing.

Tire related content
Compare your data among different tires.
A stickier tire will kick the ABS at a higher brake pressure.

For example, on UHP All season my ABS was kicking in at 800psi and on used track tires from last year it was kicking in at 1200psi

Also, observe the point in which there is no point pressing the brake pedal harder. There was no point going above 800psi on the all season, meaning find other aways to gain speed.

Not only you can see the difference among tires.
This also allows you to monitor one aspect of tire deterioration toward the end of tire lives (not counting the edge deterioration)
I use an AiM SoloDL which measures G-forces. You can use forward accel G's to measure braking forces. I am not sure how accurate the SoloDL is.

Someday, I want to upgrade to an AiM dash in my E46 and install pressure sensors on the brake lines. Morehead Speedworks makes a handy brake line with a bung for a pressure sensor.

I am curious to see what the options are for an E9X.
