yar, i have my eye on one of those... if i didn't have a brand new elec dizzy i'd try that.
you could also use the HEI as 'coil ignitor' and rather than ground the coil, ground a pull up resistor, similar to how the hall effect ones are used... (i'm a bit fuzzy on that )
many ways to skin the tach cat...
i'll test the 'tach output' with and without 15K resistor soon and get more graphs 
i'll probably end up using the VR dizzy, soem generic VR ignitor to trigger MS, then another ignitor for the MS2 spark output.
Cya, Stewart
