vteckz Posted April 8, 2018 Report Share Posted April 8, 2018 Hi Guys, We have a G4+ Atom which we are wanting to install into our boat. It is a new GM 350 motor with standard GM TBI fuel injection. The current motor does not have a crank sensor however, the ECU only relies on the distributor unit for pickup, and a live +12V on cranking from the starter. Will we be able to set the trigger up with this? Or will we need to retrofit a crank angle sensor and run the wiring? THanks Quote Link to comment Share on other sites More sharing options...
Simon Posted April 9, 2018 Report Share Posted April 9, 2018 Its likely it will have a Optical/Hall sensor with a 8 tooth chopper disk, Which will be ok for Distributor ignition and group fuel. Quote Link to comment Share on other sites More sharing options...
vteckz Posted April 18, 2018 Author Report Share Posted April 18, 2018 Thanks - so this would be setup as Optical / Hall, priority on trigger 2 as cam? What should I set the cam pulse to? Unfortunately the Atom does not have a trigger scope.. which makes things a bit harder. Thanks Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 18, 2018 Report Share Posted April 18, 2018 A photo of inside the distributor would be nice so we can confirm what it does have. If it is in fact as Simon states then the trigger setup would be as below: Quote Link to comment Share on other sites More sharing options...
