If its running on carbs you wont be able to have an ECU, unless you mean a mappable ignition system.
other than that ive no idea im afraid

you can get an equal amount of power from a single carb and its alot less hassle

Have a look at the flow chart on this thread Ron.
1. 1/4s are good for 85 bhp at the wheels.
