Rx8 2004 Changing Ecu??

Today we have found out that there is no signal from the Ecu to front rotor primary injector. ( the red injector)
What to do ???
1. I`e a "power mod" which can be used. The Power Mod will take care of ignition
map, airflow meter voltage map and fuel map.
2. Change Ecu and get the engine run on both rotors ???
Is it possiable to build in another Ecu and the new Ecu will take over or ????

I need your opinion

ECU needs to be re-programmed with " as built" data from the dealer. Each car has different module ID's that need to be able to talk to each other. The "as built" data is a bunch of Hex #'s that get added into the iDS to program the ECU to work with that car
