1983 280/1986 300 zxt knock sensor issue part 2 (noise warning!)

Here I am using a nissan 22060-30p00 which is a flat response type. Pretty sure I need the single wire resonate type for the ECU to use the signal.
Looking for a sensor that fits the L28et head and is a resonate type.
I am not exactly sure what mode I have it in, will try messing with that again. from what I understand I mode 1&2 are for A/F ratio and open/closed loop info. Mode 3/4 displays stored codes and mode 5 is like live data on modern stuff (tells you when a malfunction takes place, so you can wiggle wires etc to find why a code was set. I am still learning how to use the blinking led's the FSM is required reading to make sense of it all.
