Re: And the ECU is *fast*
RPM is Revolutions Per Minute, not second. So divide your numbers by 60. Shouldn't be any trouble at all for a ECU.nak said:Back of the envelope time:
Spark timing wants to be accurate to one degree or less. Power gains and losses are on the table at 2 degrees error, possibly lots of gains. In my bike tuning days, 2 degrees of error could cause your two-stroke to melt.
So the ECU needs to be able to know crank position something like 360 times the redline. Converting to time, we get:
8,000 RPM * 360 = 2,880,000 degrees per second
