Fuel options...

Re: Fuel options...

..........you hurt my brain....just put a big ****ing breaker bar on it and hit it with your palm...ans far as 3.8 injectors yea that'll do...I ran them with a stock pump and stock FPR...ran a little right but it picked up in the top end

but the bigger fuel pump and injectors (with lower pressue) will give me less waste of gas at idle, but will give me as much as i need in the top end, correct?


btw, what would running a HIGHER than stock fuel psi do for my mpg's/performance?

thanks

Re: Fuel options...

run stock if you can not alter your fuel tables

Re: Fuel options...

are you referring to stock fuel pressur or stock injectors?

cuz running stock injectors would make me run lean and running stock fuel pressure on bigger injectors would make me run rich, at least from what i've determined.

Re: Fuel options...

stock everything i am doubting you really need that much more fuel. do you have a wideband?

naw, no wideband.

but what do you guys think about running stock injectors at a higher psi (via the AFPR) with the upgraded fuel pump. that might do it right?

Jesus ****ing Christ I ****ing give up...good luck not blowing up that car...my advice is get a honda, that way when you ask questions like these you'll just fit in

Re: Fuel options...

you will need a scanner or some type of tuning software. the lower pressure helps keep the injectors from overspraying at idle which if you have that issue with that small of injectors god hates you. you will be altering your fueling calculations which can cause tuning issues just be warned. the larger fuel pump makes sure the fuel is there to back the pulse width of the injector without large pressure drops

not possible on a 3.4 unless you run a stand alone fueling/ignition systems. or did an obd1 or 2 swap.


bigger injectors at the same pressure are just going to shoot more fuel. you need more but not that much more.

lowering the fuel pressure means less will get to the injectors. but it can still be more than with the stock injectors.

this is not the optimal way to "tune" a computer controlled fuel injection system, but for a stock 3.4 pcm, its currently the only way.

the fuel pump probably isnt 100% necessary but cant hurt at all.

Re: Fuel options...

progressive fpr there you go it gives you stock pressure at idle and increased with less pressure call holley they will get you what you will need and you can move along

cause I like cracking jokes, but that wasn't a joke...that was just an insult.

yeah no tuning for the 3.4 out there really.

i suppose this is the ultimate way to go.

funkz fouled up plugs with 19 lb. injectors AND the AFPR at a lower psi, but then again he drove his car in the winter, and mine is just a summer car so i think it will be ok.
