cylinder 4 misfire?

[dgietzen]

I have recently recieved a hondata kpro from a friend and it has a cylinder 4 misfire. I have the factory ecu in currently and runs perfectly fine. i have tried switch coils and plugs, all the injectors have 13ohms (its a factory injectors from an 05 civic si with k20a3). it is getting spark to the number 4 cylinder with kpro installed. the only thing really left would be that the injector isnt getting a signal. if i unplug the 1,2,3 cylinder injectors or coils it dies. i have tried to clear security and reload a base map and still does it with the newest firmware update.

What im wondering is if the mother board is bad or something of the sort.

I can also datalog the ecu and monitor all sensors, plus upload any calibration just fine.
