YEOUCH! DON'T CUT IGNITION!

This is a sure fire way to erode your exhaust manifolds, piston heads, and
valves (or apex seals if you're in a rotary engine'd vehicle). It'll also
cause quicker failure of the catalytic converter, possible backfires, and
premature wearing of the O2 sensor.

It is FAR better to cut specific fuel injectors. Also make sure that the
cut injectors are on opposite sides of the stroke at even/opposite
distances on the crank to minimize crank flexing (and wear on the crank
bearings).

FWIW, My background was designing a computer for drag racing that had to
run to 15KRPMs and account for engine knock, timing, and fuel injection
control. It used an AVR micro and a Philips XA micro.
