How the Numbers are Calculated if you are curious!

The calculation involves 2 Steps.

1 a) Calculate first how many revolutions of the crankshaft there are per second instead of per minute.
8000 revolutions/min x 1 min/60 sec.
= 133 revolutions / sec.

1 b) Then using rev/sec, calculate how long it takes to complete 1 crankshaft revolution @8000 rpm?
Using straight ratios:
133 revolutions / sec. = 1 revolution / ? sec.
? seconds = 1 rev. / 133 rev/sec.
= 0.0075 sec.
= 7.5 millisec.

Bottom line is 180milliseconds faster digital air fuel gauge means 24 engine revolutions faster at 8000rpm
