Just wondering what im ment to do about my ecu in my sporting im putting in a b16a1 honda*engine in it so will I need two ecu's one for the fiat eletrics and another for the honda engine? Please help

Why? The Cinq isn't canbus. The ECU only works the engine. All the gauges have separate sensors.

Talk to the Honda folk. Easiest way, by a long, long way, would be to use the Honda ECU.
