Help Me Understand Ignition Coils
 
I been reading several threads on upgrading from stock coils to ig1a smart coils. currently im running ps1000 with oem coils and I just don't understand how you can get the trigger signal for the smart coil and make rest of the system work since the tac meter goes through the trailing coil/wiring. was wondering if anyone can shine some light on this... :(

the tach signal will now come from the ECU. the tach output wire from where the trailing use to be gets connected to PWM/DPO 1

haltech settings below.

Pull Up 5V
Tacho Duty 50%
Pulses 2

That should do it. If the 5v pullup doesnt work, set it to 12V.
