I don't know about the Impy's, but AFAIK, the 'vettes use two knock
sensors.  You are correct about the F-Bodies, only one knock sensor.

This is true.  When I replaced my '96 ECM with a '95, the ESC module had
to be replaced in the '95 computer b/c of the '96 knock sensor.  I'm now
using a '95 computer, '96 ESC module and '96 knock sensor (w/33%
desensitize).

Yep.
