why buy a tach driver when you can use a tach signal or injector pulse to get your rpm? i hooked up a 5 inch tach, my nitrous max and my plx r 500 to the tach signal and i set the multiplyer to 2.5 and i get a perfect rpm. i dont no why people waste money geting that 80 dollor driver when u can use what you got. try it people if you dont belave nme ill do a video of my electronics working off of jkust the pcm. ill even do a right up on how to hook it up. also have my apexi boost controller hooked up to it. i find it wierd that everyone says that you "NEED" a tach driver for anything using a tach signal

 

thats cool, u should do it!
