4 channel COP with 4 channel CDI on a M800 OEM (Evo IX)

[konstantinosIX]

Hello,
Does anyone try to connect a 4 channel COP with CDI on a M800 OEM for Evo IX?
I am wondering what he did with power hold function!
If you try to change the ignition from 2 channel to 4 channel then you will have an issue with the Power hold of the M800 OEM ECU.
It will be on forever!!!!

This will cause a problem because IGN4 on the M800 OEM is used to control the ECU relay with some circuitry on the board. Pin 22 goes to the warning light and Pin 57 is the negative side of the ECU Relay coil. The OEM ECU was not intended to work with a 4 coil setup. Disconnecting the wire from Pin 57 and find an alternative way of switching the relay might work.
