Mike, sure we could draft up a quick and easy paper on the logic a program
needs to retard the cylinders...the complex part as you mention below is
the filtering of other noises.

The J&S uses DSP. Other then being disabled under 1500 RPM, It connects
to TPS and disables itself on de-acceleration where the engine is more
prone to pickup piston slap as knock. These 2 combinations allow it to be
used for the full scope of the useful rpm range.

Back to C/R....what you guys think.. 9:1 as well? :)
