I understand your point, but am still puzzled, then did the "old" ECU's take over 90Deg to calc the new accelerated rpm, no matter the tooth count? And the new ECU's cannot now account for any new acceleration with 4 magnets for at least 90 deg of crank rotation, no matter how fast they do the calc's, since it takes a starting pulse and the next timing pulse for an rpm calc, at the minimum, which on a 4 magnet wheel is 90 deg, correct? It seems odd so many companies offer much higher toothed aftermarket timing wheels in often race use, and there is no reported advantage. I guess I should be soon seeing that dead horse.
