Type of carbs to suit 4ag

[Project D]

No, what I'm saying is that way easier to tune an ITB setup than a carburetor, basically because on an injection setup you just set a value on the ECU (standalone) via a computer and you have a direct feedback of what you are doing via all the sensors.

On carburator (FCR or sidedraft) you have to change parts (idle jet / main jet / emulsion tube) till you find the right setup.
And the only sensor is YOU ! (your eye -> spark plug color, your ears -> how the engine behave, and your nose -> how it smell)
Some peoples use an AFR sensor to make the job a little bit easier, but if you have never done that before (with someone who have the knowledge and experience) it will still give you a massive headache

For the map sensor, since when you need that kind of stuff on a carb ?
Carb are mechanical device so they don't need any kind of sensors !
No electronic stuff on that kind of setup.
