I have just installed an IEX in conjunction with an M8 ecu running LS1 denso coils. This is all running on a 6 cylinder ford xflow. I have it all wired as per your drawing and it is all working but the question I have is the IEX has to be wired in firing order from first to fire onwards and the box has 8 outputs, how does the IEX know only to fire 6 outputs on my engine as it only has the one input form the ecu.
Thanks
Jason
