ok, heres the final graphs
http://www.materials.unsw.edu.au/~sford/tach-testi ng2.html
the top 3 are taken directly from the Jaycar HEI "tach output". there is a little bit of noise in there. max of about 300rpm?
the bottom two are taken directly from the coil negative terminal, but with a 15K resistor in series between the coil and the MS.
i think the bottom two are better quality and more accurately track the rpm of the motor..
so whatcha think?
Cya, Stewart
