Guest grant620 Posted March 11, 2013 Report Share Posted March 11, 2013 Hi. Got a G4 Plug in EVO board which is currently running wasted spark on Ign1 and Ign2 outputs. About to swap to a coil per plug firing system and have wired the coils into Ign3 and Ign4 as well (don't use Aircon so don't need the A/C functionality. Stupid question though... With a Firing order of 1/3/4/2, do I wire the coils to Ign outputs as follows: Ign 1 - Cyl 1 Ign 2 - Cyl 2 Ign 3 - Cyl 3 Ign 4 - Cyl 4 OR: Ign 1 - Cyl 1 Ign 2 - Cyl 3 Ign 3 - Cyl 4 Ign 4 - Cyl 2 Thanks Quote Link to comment Share on other sites More sharing options...
Simon Posted March 12, 2013 Report Share Posted March 12, 2013 1-1 2-2 etc ECU sorts the firing order from there. Quote Link to comment Share on other sites More sharing options...
