I'm in need of trigger wiring information regarding launch control. I have read that a 5v input is needed, and have also read that just a ground wire is needed.
I have several cars running vems with turbochargers. I have been using just MSD ignitions two step modules and have been swayed to remove those for finer VEMS ignition and fuel control.
I am using 3 cars with 3.6 boards and one might be a 3.7 If you can explain the pins to be wired and switched, I will be grateful.
Thank you John
