ECU question for the technically inclined...

This is our guess too Steve but still....????

And is it actually that simple? I mean, does anyone have any experience with
"speeding-up" the processor on ANY ECU? How does this affect the functioning
of the ECU? Or the longevity of the engine/ECU?

If operations, interpretation of sensor-INPUT  to the ECU, etc. are
clock-dependent (as the rev limiter that moved way up in the stratosphere
seems to indicate) we should assume the same for the ECU OUTPUTS, correct?
How in h$ll does it calculate fuel, ignition advance etc. and sends the
commands to be executed?
