If we have 8 cylinder engine that have 8 coil per plug Ignition system how we can connect it with motec m84 ?

Simple Either waste spark ( 2 coils per output ) or add a IEX for 8 ignition outputs

Thanks for your feedback I will chnge the Igntion system to waste spark
in waste spark every coil is connected to two cylinder, my qustion In which cylnider each coil are connected ?

Hi,

You need to connect the cylinders that fire 360 degrees apart for waste spark, the easiest way to work out which cylinders these are is to do a star diagram like this, and use the joined cylinders in waste spark.
