LS1 knock sensors are a single wire and later Gen4 are a twin wire.
Think of LS1 style as just a simple microphone collecting noise samples, whereas the Gen4 style puts a noise down one wire and collects a new noise back down the other wire. Gen4 computer then compares induced noise to returned noise and spits out the differential noise as a result.
The physics/construction of the knock sensors will suit one process but not the other.
Same solution for LS3 as LS2 below.
