Dear Sir,
Thank you for the reply.

Thank you.

I have been a Infiniti and Nissan Tech for 27 years. The Injector Pulse is determined by the computer based on the firing order. So I understand your logic as far as a balanced fire where you would think the computer does two cylinders at once. How ever, the way Infiniti has the firing order it's done in numbered order. So bank 1 is cylinders 1,3,5 and bank 2 is 2,4,6. So when it does a firing with injector pulse and ignition coil, it is in 1,2,3,4,5,6 order. The intake timing operation also plays a factor in how it keeps everything timed when firing also. So injectors and coils are bouncing right to left of the engine forward to back and back to forward. That is the way the firing system operates.
