Tach Signal

Kind of OEM, but more mod tech.
Does anyone know what the factory tach signal is on a renix. 2 pulses per rev? I am trying to program the LS1 ECM to work with the Stock tach without using the dakota digital tach converter.
 
Idk if this will help, but I put a 96 camaro 3.8 in my 86 comanche, and simply plugged the tach wires together...It may be that the LS1 tach signal is the same as the renix.

3 per revolution I believe is what it is...but don't quote me
