I have a t3 .48 trim turbo with RC 195 injectors, and heres the deal. The car doesnt have a tune, but its ran great for the most part. When I get to boosting around 5 psi with the wastegate spring set at 7psi on a tial setup, the car wants to cut out due to a fuel cut issue I think. So I was going to up the injectors to 560cc out of an evo which it should swap over due to the harnesses being the same with the RC injectors, but thought I might try 110 octane fuel first. I dont have a fmu, but I do have a walbro 255 in the tank. Im 95% there with my project, please help me get over the top.
Tune it.
180hp in 1989 or 260hp in 2008, you decide. Quad < Ecotec
Ok you have no FMU, so you put what size injectors in? 195'cc?? how are you getting extra fuel. has it been tuned?
FU Tuning
I got a vortech fully adjustable FMU 55 shipped
Get the bigger injectors and tune it. No need for a FMU if you HP Tuners. And 195's are way too small.
I was thinkning about just getting biggers injectors and then a map 2 or 3 bar map sensor. I dont really want to tune it.

you have to tune larger injectors,the ecu doesn't have any idea that you have larger injectors for one,it will over fuel cuz the pulse width on your stock setup isn't the same as pw on bigger inj. if you're not going to tune and you stay at low boost use the fmu,all you have to do is figure out the proper rate of gain and get an adj fmu it's easier .

Do you even have a wideband? From the info you provided, you are "wishing" for your engine to blow up. Provide some more info on exactly what you have for your setup, so that the "Experts" , certainly not me
, on here can help you out. Don't get bent out of shape when "Open & Honest" communication is being put forward to you. This is how you learn, especially in a Forum type setting.
SOLD!!!!!!!!!!!!
Sorry guys I mean i dont want to tune it but I will if that is what needs to be done. I was tlking to a guy near me who specializes in forced induction and was thinking about a sfmu neo but didnt know it that would do it. Also I tried putting bigger injectors in the blue top DSM's it ran great for a min then went back to @!#$ does anyone have blue tops in their car? if so lemme know how u got them to fit please. I also did put the resistor to change to low from high so its at the right OHMs.
The setup so far is
48 trim turbo
Turboxs BOV
Intercooler
450 DSM injectors
Walbro 255
i think that is about it
wanna know anything else just ask
This kid is a moron, i think we just need to give up.
If he doesnt know this, who is to say the turbo is even hooked up right?
How am I a moron? I'm asking you guys cause I want to get everything I need before I tune it. I just want to know. If anyone has jdm blue tops in their setup. And fyi the car ran with the old injectors just not the greatest its alll hooked up right so no need to name call I just need some help finishing it up. So if someone who isn't gonna make fun of me could help I would appreciate it. I just want to have it done so I can get it tuned and tae it to the track. Thanks guys
Simplified: NO TUNE = BIG BOOM.

If it's not finished, you shouldn't be driving it.
As far as the injectors.... you need to understand how the system works. Stock you have 19# injectors, the car fuels X% with these injectors. If you stick, say, 42.5# injectors in... the car is not going to see that the fuel range increased, and it's still going to fuel X% of those injectors, which, in this case, would almost double fueling. For the car to run, you NEED to change the injector constant with HPTuners, the PCM will then make the necesary fueling adjustment to compensate for the larger injectors.
I am not driving, y does everyone think Im @!#$ stupid

Hey, if the shoe fits....
Tune your car. It's that simple. Sure, it's a little more money to do it correct the first time, but you'll be regretting half-assing it later when your engine goes BOOM.

ok heres the deal I went to the junkyard and got used oem injectors for the car, out of the ohv motor. I went to put them in and I get injector open circuit across all my injectors I was wondering why that is? I didnt do anything to the wiring could those injectors be bad? I doubt it but what else could it be the car is rejecting them? Got any ideas for injectors I have the tune which Im saving up for, but I need to get the damn car to run so I can move it to the shop to be tuned.
I had my car towed to the tuners shop on a flat bed truck. AAA Son. Get it. Then tune you Sh!t. Don't get upset when Ryan tells you your going to blow your motor. If Ryan says KaBOOOM dude its KaBOOOM!
Ok I understand all that with the car needing a tune, but I dont understand why Im getting an open circuit with the oem injectors out of a ohv 2.2. The car wont start going to try the old rc injectors that car came with so I can at least move it. I do need everyone to not give up on me, just I want to get the right injectors so my time at the tune will come out with positive numbers.
Earlier in the thread you said you put int the resistors, then you said you never messed with the wiring. Which one is it? What year did you get the "stock" injectors out of?

I took it to the shop for him to figure it out so hopefully it should be fine after that
did you plug the injector harness back in when you removed the fuel rail? the odds of all injectors failing is slim to none.
