This is a different concept altogether.  The module generates an est signal
based on the time between pulses.  The pulses happen once every sixty
degrees.  Engine rpm and crankshaft speed (is angular velocity the correct
term here?) are different items altogether.  If you could change the
diameter of the crank while it spins, it would still take the same amount
of time to complete a revolution.  The module is interested in counting
pulses and generating pulses.

   well if the tpu timing instructions are looking for a specific length of 
both high and low in the wave and yr current trigger doesnt give it the 
correct  breaks maybe this could be the issue. heres the best example i cn 
type up.

  ____I-----I____I------I   say this is a stock trgieer patern minus the 
interupt. 

  say this is your pattern with yr current wheel 
  __I--------------I__I--------------I________

  even though its still effectivaly trigering and counting pulse maybe its 
say more sensitive to the on and off cycles than we know about now.
