Software Dyno...

[Dave Zug]

So I get 500 samples in 1/4 mile.. thats like 38 samples a 
second average.. 27 per sec at 50 mph. I'm not sure if thats any 
better than the 8192 aldl recording vss or rpm.. At 50 mph I'm 
almost at the top of second gear(+-70 mph w/ 2.73's) . at speeds 
lower than 50 mph the number of samples of coarse is lower and the 
distance between pulses is fatter. as long as time is more precisely 
measurable in some budget acquisition package then theres an 
advantage over aldl. the other bonus is the wheelspin tuning thing, 
which has some interest I see.
