Thread: LS Custom Ignition Configuration

  1. #1

    Default LS Custom Ignition Configuration

    I'm running the 24x LS crank sensor and stock cam sensor. I want to define as "Custom" for the ability to set coil dwell. My question is what would the correct cam sync option be? Thanks in advance.

    And also the Inductive Delay.

    An LS engine with a 24x crank trigger & a rear mounted cam sensor, should have a "Single Pulse" (1x) cam reluctor.

    Thanks Danny for reply. I need to be more clear on what I was asking though. I already have the EFI running, but I have been reading about dwell with the stock coils. When I go to the Custom Ignition Parameters configuration I can choose 24x crank, then on the cam sensor single pulse, etc., and Digital Rising/Falling etc.

    Any advice is appreciated! Also, setup info on the Inductive Delay? None of those parameters were shown when I was on just the "LSx 24x" ignition setup before.
