88 Speedo what LS1 Tach Output?
Just got HPTuners and ready to start turning off some stuff and getting speedometer and tach corrected, etc.
What is the correct number to plug in for the output pulses to work with the 88 tach? Current setting if 40K, not sure if we should double or divide by 2.

I don't know about HP Tuners but in EFF Live you change the 6 to a 12.
For 2 pulses, use N= 6 < Stock
For 1 pulse, use N=12
