At Shawnee, someone asked if the spark control module # 16131231 was a bandpass filter.
Well, I tried to find out, but I have been unable to contact the person that might actually know. I did contact another associate and he pointed me to the applications list available online.
What I found there:
The part is only listed as used for the 1995 7.4 (454) engine and none other. It may well be a band pass filter tuned to the big block, but I can confirm no more than that and that the part is out of production.

Matt;
This is the info I have on the ESC module.
The ECM (Electronic Control Module - engine computer) is signaled that knock is occuring by the ESC, or Electronic Spark Control module. The ESC module is a band-pass filter and logic driver circuit that is connected to an acoustic sensor mounted on the engine block. Normally, the output line of the filter going to the ECM is held "high," or about 10-12 volts. When the filter detects knocking-type sounds, it "grounds" the signal line going to the ECM.
