Niggz Posted April 26, 2020 Report Share Posted April 26, 2020 @Adamw We have a LS Running an extreme. If you turn ignition on to say check a gauge reading or prime the fuel system, when the key is cycled to the off position she'll backfire, also had a Holden V6 stock car running an Atom, With Key On Eng OFF a coil will get hot as if it's being charged. Is there some way to set up the programming to only dwell the coils when it sees an active ignition trigger? Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 26, 2020 Report Share Posted April 26, 2020 I moved this to its own thread since it wasnt related to the one you posted in. The ignition outputs will remain at ground until the engine is turning and the ECU is commanding dwell. So for the coils to charge and spark it sounds like either you have something wrong in your config or perhaps wiring. The LS coils trigger at very low voltage so make sure the signal ground pin is grounded to ecu sensor ground and nowhere else. Can you attach the map from the LS for me to check too.
