Michael Dolan Posted July 19, 2010 Report Share Posted July 19, 2010 Hello, I have a new LemG3 ecu and am planning to use it on a 3-cylinder motorcycle engine. Firing order is 1-3-2, crankshaft phasing is an equal 120 degrees. So in terms of sequential firing the engine it can be expressed as follows: cyl 1 0Â° cyl 2 480Â° cyl 3 240 I wish to fire the ignition fully sequentially so how do I trigger. As the engine fires like a V-6 it would seem normal to use a 36-1 wheel, is this ok or would I have to use a cam sensor also. As I have no maps loaded up yet might it be best to get the G4 firmware upgrade done now. Can this be done online? there is no main Link importer in my country (Ireland) and I don't really want to post the unit. Quote Link to comment Share on other sites More sharing options...
