Re: Sensitivity of GM Knock Sensors

Hmm, well. Ya can 0 out everything that you can, and then change everything
else.  Then run a file compare.  Then use promedit, and a correction of .352
(Double check this).  Then try looking for a string, of what maybe the
timing adders.   Or just hac the code for the chip,  being able to read code
is the beest answer, but the above will for getting it done...  Course ya
got to verify all of it.
