i might be picking up an fb, i thinnk id like to supercharge, i had an 88 before but now in interested in the fb. im just wondering if the fb is computer controlled or is it just caruerated controlled any info would be great!
i know that that not my question.some cars that are carbuerated dont have a computer, im just wondering if the 1st gen ar computer controlled or not and if i was to supercharger one would i have to get some kind of computer or something?
nope, not computer controlled. and as for the supercahrger, look up camden superchargers.
rotary specific, and made to use a holley

Are you talking about an ECU? ECUs are for fuel injection. Carbureted engines don't have or need ECUs, fuel is metered by the carburetor mechanically. Man, no offense, but you need to do some serious research before you'll be ready for a project like this.Originally Posted by dkaszak88

just so u know there is a such thing as computer controlled carburetors. look it up.Originally Posted by PercentSevenC

First off, If you want to go with a supercharger. ur best bet is to stay with a carbed one.Originally Posted by PercentSevenC

Once you get into FI your gonna need a EMS, huge fuel pump. heat sheilds, and the list goes on. and believe me i speak from experience.
Carburetors are mechanical in their fuel metering. That means that they are not gonna change how much fuel they deliver no matter what you do to the computer.

This is probably the last nice-spirited post you are gonna get in this thread if you keep up that attitude. Not a threat by me, just a heads up.
i wasnt trying to be rude at all and ifi came off tht way i appologize. but there really are cars that came with electronic compute controlled carburetors. in the 80s and they make aftermarket carburetors for trucks for off roading and stuffOriginally Posted by theNeanderthol
Dude, everyone here has been pretty nice and patient in answering your questions. And frankly they are questions that could have been answered by you reading the FAQ section of this website. People here get kinda pissed off when new members come in and ask questions that have been answered 10 times over, and could be answered yourself.If you are not gonna listen to these very intelligent and prominent members of our forum, you are gonna get flamed to no end.

There are cars with carburetors that have a computer feedback system; the first gen RX-7 is one of them.
The computer will take inputs from various sensors and control vacuum solenoids. It's mainly for emissions purposes. Any modification to the computer would not affect the carburetor itself. The computer does not control fuel delivery.

^ Finally, someone with some sense.
The carb'ed RX-7s do have an ECU, for primarily emissions reasons. It controls ignition cut, the solenoids and a few other little things.
That said, the ECU is basically irrelevant for modification. It can be eliminated very easily and won't freak out under boost (it has no way of even knowing the engine is running under boost).
And for the record, MANY carbureted cars came with ECUs for emissions purposes. Some even had O2 sensors and closed loop...
