so my LT10s Leading Coils arent Firing, everything is wired up correctly, i have double checked it over, ecu is not programmed for X4 box if anyone was gonna ask

So heres whats going on, the trailing coils DO fire but not the leading, i have tested the coils on my friends fc and the leading coils and Igniters work just fine, everything is good on the ecu side, i crank and the orange flashes and the green stays on and no red at all,

even in test mode all the injectors fire and Just the Trailing, the leadings don't Fire at all, in test mode the red light does flash slowly

is there anything in the settings that would prevent the leadings from firing and only the trailing, i couldnt find any settings like that on the microtech software, i'm using a Stock t2 map that is stickied on this section,

any help would be useful, thanks

 

these ecus will not fire the trailing plugs during cranking..

are you double and triple sure there is no fault in the loom where you have wired the leading as trailing and vichy versa

 

yeah i doubled with the wiring diagram, the leading and trailing fire and the grey with red goes to the leading , i even tried the grey with black to the leading also still nothing, even in test mode only the trailings fire

 

Have you checked the wiring com7ng out of the microtech, one of my harnesses was pinned wrong and in turn my cas readings weren't right.

 

yeah i checked the wiring from the ecu and the wiring diagram, its pinned correctly
