Does any one knopw what type of pulse is used for the tack on the SR?

 

i'm sure u know this from research but the dohc tach from the '91 and up 240 will work to recieve the dohc tach signal from sr. I know u r asking a more complicated question than that but just gettin the post started

 

Yes I was wondering about the signal its self. I buying an Autometer tack and would like to know if this one would work (it had been sent back and refigured to 4,6,8 pulse I belive. i will call the company and find out later this week.
