Thread: New Install Timing Issue

  1. #1

    Default New Install Timing Issue

    I've installed a Dominator on a twin turbo 427 LSx motor that had an BS3 originally. With the BS3, it was converted to a 24 tooth crank trigger, magnetic sensor, and aftermarket cam sensor with a magnet on the cam gear and a Hall-Effect senor I believe. We removed a tooth from the crank wheel to make it a 24-1 configuration with the missing tooth 9 before TDC. The issue I'm having is when the engine attempts to run it sounds like it has a severe timing issue. I have run a system log and have confirmed that both crank & cam signals are being read. I've confirmed all coil wiring is per the wiring diagram for the COP, we're using the 558-117 harness. Would anyone ave any additional items to possibly check to get this thing to fire off? Would the crank trigger with the machined tooth be the problem? I see no difference in it vs the Holley 36-1 wheel, but now I'm second guessing? Thanks in advance for any help!

    In the Custom Ignition Parameters, I have the choice of Waste Spark & COP. We're using LSx coils and I have Waste Spark as the setting. Should it be COP? Thanks Danny for the info.

    Yes, "DIS Coil On Plug".
