You would like to think that; however, the ABS ECU is not that sophisticated. It only measures speed to prevent lockup. It does not correlate vehicle speed to wheel speed, at least not in the S13.

Plus the speed between the gearbox output shaft and the front wheels will most likely be different under braking.

The VSS is mounted in the gearbox and measures gearbox output speed for displaying and speed control purposes. The ABS rear wheel speed sensor is a separate unit that goes in the rear diff area. Check the FSM for details.
