Speed Hut Tach calibration
 

Hey guys, I’ve replaced the stock tach with a speed hut tach and just a little confused on calibration. I grabbed the signal coming from the blue yellow wire at the pfc, I was just wondering do I calibrate the tach to 2 pulses 4cyl?

Yeap, you've got two ignition events per e-shaft rotation, just like a 4 cyl has two ignition events per crank rotation :-).
