The engine is a 1991 GM 305 TPI with intake/exhaust mods plus supercharger.
The ignition system is a MSD6BTM system. I don't want to disturb the knock
sensor already fitted, so I was thinking of interfacing to a new independant
unit. I would like to measure the amount of knock so that I can optimise
the ECM tables rather than relying on the BTM to add retard under boost
whether the engine needs it or not.

What would be most useful would to have the spectrum signature of the knock
events. As has been already suggested, I could induce knock and analyse the
transducer output. However, with 420 bhp on tap, this could become an
expensive exercise if I overdo it.

Later,
