My opinion,
Fuel injection has it's good points and they are; Better starts (versus a poorly-tuned carb) More mileage Less carbon build-up It's bad points, Too many sensors to go bad One "too many" computers to go bad You need another computer to fix it when it pukes It has a electric fuel pump (that you couldn't give me) because they pull too many amps, are too noisy, burn too many cars to the ground when their roll over switch fails It has injectors that plug up too easy for me It costs too much for what it delivers Too hard to fix on the side of the road I'll take a carb (in other words) 'cause I can make it work without a diagnostic scanner around. |

I agree. I'll take a carb over FI anytime. My brother had a 87 with FI stock and drove him nuts with computer going out, sensors going out etc. He sold the truck after getting it running enough. If you decide to go with aftermarket FI get ready to get a 2nd mortgage since they cost way too much!!

personally, i'd take EFI over a carb any day. true, any idiot can work on a carb, but can any idiot make one deliver the proper air/fuel ratio at any throttle position? NO! with the EFI setup, it is constantly adjusting the A/F mixture for maximum performance or efficiency, depending on what kind of system it is. 90% of the time, this will give you better fuel economy, as well as better performance.
also, i would go with some sort of multi-port setup as opposed to a TBI setup, unless you're going purely for mailage reasons. stock type TBI setups are great for milage, but when it comes to performance, you might as well stick a 1bbl carb on it. THEY SUCK! |

If you have the cash, FI is the only way to go.

I'm another idiot I guess. I'll take a carb any day over FI. FI is way too complicated for what you get. I can take a carb and turn it inside out and back again.
I guess it's a matter of coming from the old school. It seems that most of the ones who like FI are the younger crowd. They grew up on it and carbs are like a science to them. These are also the ones who don't know jack about carbs. IMO, TBI sucks bigguns, and computers don't belong in vehicles.

If I had the cash, I would go FI. There is a reason why the cars now days are coming with multi-port FI. It works and it works well.
Yes there are more sensors, parts, etc, to fail. But it does what it does well. Constantly monitoring autmospheric pressures, oxygen, etc. Can't take a carb from sea level to the mountains and continue driving with no adjustments. But for the price and hassle, I will stick with a carb for now. Some day I want to do a FI convertion just to say I did it. ![]()

Fly by wire is a all computer controlled system for steering a airplane. If electrical power fails, plane goes plowing into the ground. I hate this. I dont think computers belong in control of airplanes. But if it wasent for fly-by-wire, there would be no F16's, no SR-71's, no F-117 stealths etc. All airbus commercial planes are FBW. Like it or not, they do the job, very well. I used to be a die hard carb guy. Not anymore. When you can adjust your timing, air/fuel mixture and lots of other stuff after a run with your labtop inside the car, thats ultimate tunability.
