classd99 Posted December 20, 2020 Report Share Posted December 20, 2020 Hi guys, I am new to this ecu and I would like to confirm if my configurations are correct for semi-sequential ignition and injection wiring before I proceed with the project. All injector are connected as per cyliner numbering i.e. inj1 --> Injector Cyl #1 ; inj2 --> Injector Cyl #2 etc.. All ignition coil (CoP) are connected as well ( ign1 --> CoP#1; ign2 --> CoP#2 VR sensor @ crank is 36-1 - there is no cam sensor, hence semi sequential. Please le me know if these wiring are correct. Quote Link to comment Share on other sites More sharing options...
Vaughan Posted December 20, 2020 Report Share Posted December 20, 2020 semi sequential injection is intended for when you don't have enough injector drives for the number of cylinders, it still requires cam sync to operate correctly, multi point group is probably the correct mode for you. For ignition if you don't have a cam sync you want to use waste spark not direct ignition which requires different wiring. Quote Link to comment Share on other sites More sharing options...
classd99 Posted December 27, 2020 Author Report Share Posted December 27, 2020 Thanks! Does it mean if I have 4 injectors I should use all channels irregardless of sequential or wasted spark ignition. is that correct? Quote Link to comment Share on other sites More sharing options...

For injector wiring, yes if you have enough drives then the easiest option is inj1 to cyl 1, inj2 to cyl 2, etc Quote Link to comment Share on other sites More sharing options...
