Fuel Management
 

Think 450cc injectors and a fuel regulator with gauge will be alright to see if i'm runnin to lean on my zc?

You will easily wash your rings, you cannot turn the fuel pressure low enough, the 450cc injectors are simply to big, I even tried 380's with the fuel pressure at 20psi, and was getting around 11mpg and it ran very doggish. The best way is to get some type of controller, apexi afc device, fields controller or a SMC controller. this changes the input voltage going to the ecu from the map sensor, leaning it out. thus letting your car idle with such a large injector (AFC HACK)

which one is the cheapest?

Re:Fuel Management
 

probably the SMC, but it may not be the best, I have never used it.

People like the AFC

Re:Fuel Management
 

that means that i would have to take the car to get it tuned on a dyno?

Re:Fuel Management
 

well if you want it to run good, and make alot of power..? yes

or you can get a air/fuel gauge and just wing it yourself, just make sure it doesnt stay to rich, and it never goes lean.

Re:Fuel Management
 

How much does it usually run to get a car fine tuned? :-\

Re:Fuel Management
 

About 1 hour on the dyno, to get a base setup going.

some cars are harder.. tough to say dude, call around and get some pricing.

ok cool, i think i'm just gonna go with the Apexi S-AFC and worry about upgrading the fuel pump later, what do u think?

Re:Fuel Management
 

i wish i lived near a dyno. the nearest dyno im told is miniapolis USA, other than the college dynos that arn't for public use, ----!
