Since this post, I've gotten the B&M FPR and B&M FP gauge (that goes onto your fuel filter). The ITR FPR puts out 50PSI

Stock GSR FP should be 37-38 from what I understand. So, I brought that down. I also got an air/fuel meter, but haven't hooked it up yet.

It's at the shop right now getting tuned. I'll get it back next week *hopefully*.

 

narrow range af gauges are all but useless i had a turbo integra ran it for a few months so rich that my cat clogged and exploded ended up coming out the end of my exhaust in pieces no bigger than a marble dont trust them trust the dyno and their wideband

 

You eventually might want to go to DSM 450cc injectors. You might also want to check your fuel pump, my car would die or jerk and then I replaced my fuel pump and it ran fine.

 

Once I go turbo, I'll probably get better injectors, but not before then.

 

After I get it back from the shop and see how it's running I'll decide on the dyno. There isn't one where I live so I'd have to drive about an hour to get to one. After the turbo goes on, I'll definately be going to tune it at the dyno shop.

Thanks for the info!

 

the problem is probably your injectors. 40 psi of fuel pressure will put out more fuel on 250cc injectors rather than stock injectors. if you had a VAFC or SAFC you could turn down the fuel.

 

Couldn't I lean it down with the adjustable FPR? I I give the injectors less fuel pressure, won't they spray less fuel?

 

i believe it also has to do w/ injector duty cycles. eventhough you have larger injectors the ecu thinks they are stock injectors. when it injects fuel at a certain duty cycle it is actually injecting more fuel due to the larger injector size.

 

Can running too rich damage your engine? From what I understand, the cylinders could become gas-soaked causing fuel to get pass the rings and into the oil. Then you have the potential problem of oil break-down and internal parts wear.

The reason I ask is because I have a 92 CIVIC hatch with a new 2.0litre build from Import builders. I'm running a T3/T04E garrett and a Hondata Stage2B ECU. My 720cc injectors are dumping gas like mad. But I can't get to ATL until next week to not only have the car dyno-tuned, but tuned for daily driving as well.
