Regardless of what brakes you have, your abs uses a calculation between wheel speeds to simply pulse the solenoids.
its calibrated to the brake system. Even between 2nd generation models they 'tweak' the ABS parameters. If there's more braking force it may not unlock the brakes as expected. So any major change you'd test the different driving conditions.....

That's not how they work. They use the wheel speed sensors to detect lockup. If one wheels stops spinning, it just pulsates the pressure to that line. It basically cuts off the line pressure many times per second. And will actually over react if you have more braking because it will sense the wheel stopping and keep bypassing until it's under control. The parameters on these are simply monitoring the tone rings rotation vs vehicle and other wheel speed and reacting accordingly.

It doesn't measure the hydraulic pressure or flow. the parameters that it follows is based on the stock HARWARE as well not just sensor input. Different vehicles use the same Kelsey-Hayes modules but with different software. So it is not only logical that if you alter the hardware it alters the ABS performance, but as well from other people's experience of upgrading their brakes and performance with abs or traction control gives an undesired effect. These are 'blind' upgrades, not engineered, with fingers crossed hoping for the best.
