Actually, most detect wheel lockup by measuring the rotation of the
wheels and perform antilock by releasing the brake (or pulsing it) on
the wheel(s) that has/have stopped turning (assuming other wheels are
still turning).

Hi Dave,
Most ABS systems use a tooth wheel at the hub. I'm pretty sure most
system detect a wheel slip condition by calculating the deceleration
rate
of the wheel.
Although its not EFI, many of the same processes apply to ABS
