ok as most of u kno i turbocharged my 7afe and right now im in the tuning process i had to dyno the car like a week ago and i cnt because my car keeps choking on fuel i been tuning my car with the emanage and it still chokes on fuel so any body with the 7afte and a emanage in it plz let me kno how is it setup like the 4 little knobs it has like where are they and what size injectors u guys have and how u setup the emanage with the software? the size injector tht u guyz have i want to kno so tht way i can compare i hvaew 315cc injectors.

Fuel pump?

the 315s are good for just under 200hp. You are choking, you need bigger injectors.

Exactly, after seeing 315 I didn't need to read anything more. After you run some larger injectors you may want to look at your fuel rail.

im using a walbro fuel pump....and if i use larger injectors it just going to be worst its going to choke even in more fuel. also idnt kno but can it be because idnt have the 3sgte map sensor on it yet?

I will never post another reply to any of your questions.

You completely ignore everything anyone says in other posts you make.

If you continue to do things half a$$ it's like you are driving a bomb.

I hope that motor goes pop the next time you drive it

i did everything u guys said the same step u guys told me everything in order idk what could ive possibly done wrong the car running fine it just chokes on fuel in high rpm all i have to do is tune it so idnt what u talking about i hvae the emange on it im tuning the car but still chokes on fuel all i wanna kno is why its doing it? the 3sgte map sensor is not on yet cuz the car isnt boosting cuz i took of one of the intercooler outlet so it doesnt boost till the car stop choking on fuel...so i wanna kno if its cuz the map sensor not on it ?

idk what u talking about cuz i did every single thing u guys told me and the car still chokes on fuel i tune the car the emangae on it idk what else to do seriosly anybody who has an emanage let me kno how u guy programmed it plz.

First off, you need bigger injectors.

Secondly, you need to go get your emanage tuned professionally.

Lastly, put the map sensor on

If you don't get this stuff done, you are going to be blowing that motor in a relatively quick fashion.

you dont know what there talking about??? maybe its the fact that 3 people told you...not suggested, but told you what was wrong and you completely ignored them

chances are i will havse the same problem then, im still in the buying phase and was planning on buying the green top supra 315cc injectors but now that i see it needs bigger ones. What do you guys suggest, the turbo probes? or sumthing else?

Larger injectors will not be worse. Who told you they would be. If it was your tuner then god forbid find someone else to do it.

>>The car is choking in high RPM because the injectors are at max duty. They can not flow any more fuel then they have. Hence why it is having issues. You want more power, you need more fuel. More fuel only comes from better flow. Better flow is created by larger injectors. I could care less if you are running a Power FC and claim your tune is perfect. Small injectors will not cut it. You lean out the motor, it goes bang.

Now this is exactly what you need to do. Go to RC Engineering and purchase some 350cc or 360cc injectors. While those are being shipped you then go out to your car and install your 3s map sensor. You then reconnect all the plumbing which you have moved around to fix your leaning issue. Hook up your intercooler piping to the turbo. Then you ask a friend with a truck who can tow your car, or you call a tow truck. The car is then towed to a tuner who knows what the hell they are doing. You then let them work with your emanage and map your car properly. When they do, you ask for a conservative tune and a high tune. You then drive the car DAILY ON A CONSERVATIVE TUNE. Do not, I repeat do not **** with your boost controller when you feel like it. You leave the boost settings at exactly what your tuner tells you. >>

ok this what idnt get ur saying get bigger injectors when the car is already choking on fuel because to much fuel is going threw second why did everybody tell me to buy supra top lime green injectors? third the car isnt in a critcal state all is doing is choking on fuel. im a take ur advice im a buy rc 350 injectors i hvae a question thoe do they fit right in or no? also i put the injectors before my turbo was even on and it was still choking on fuel .

How do you know its choking on fuel? Do you have a wideband? You cant tune a car without one.
It actually sounds like your hitting fuel cut from having the stock map sensor on there. You need a 2bar map.

doesanyone know the part # for the RC 350cc or 360cc injectors that wud fit the 7a. thanks

And the map sensor will take you all of 2 minutes to install. Unplug one, plug in the other. Done.

This really isn't something you can half-ass. If you don't do it right the first time you will blow your motor.

Like Art said, how do you KNOW that your car is choking on fuel in high RPMs? do you have a wideband to show that?

ok guys im a tell u exactly what my car is doing when i turn my car on u can feel it stalling i mena like the rev is prob 2 point above 0 another thing when i rev the car u can fee it like pushing idnt kno how to explain it but it kinds of gets power tehn lose it get the power then lose it like tht it just not right also i kno its choking on fuel cuz the freaking gas smell it live in my car when i turn it on and if u put ur finger in the exhaust it stinks like stright up fuel. it prob can be tht its cuttin on fuel also my car has the emanage setup up and running the difficult part is tuning it im not the one tuning itso this what im a do im goin to install the 3sgte map sensor turn on my car see if anything diffrent if not im a put the coupler the attaches from the intercooler the turbo and turn it on then see if anything diffrent then im a take it to m mechanic and he goin to tune it see what happens then but getting bigger injectors is not the problem cuz my injectors are so big it choking on fuel i get bigger ones and it just going to *******drown in fuel. my ring and piston are going to b all **** up if with these injectors doesnt work yea im a try ur way. what u mena by wideband the air/fuel ration gauge yes i hvae tht on the car is running really rich.

I give all of you a lot of credit for even reading THROUGH these posts. Even if I knew HALF as much as a lot of you, I just don't have the patience to read through the half typed words that comprise a REALLY Fing LONG run-on sentence.

ok are u here to correct ppl's grammer or help them figure out whats wrong with thier car?

i cant even read your posts, but i have 3 questions.
DO YOU HAVE A WIDEBAND?
if not, how are you "tuning" your car? do you know what "tuning" is?
having one long run on sentence makes your posts REALLY hard to understand and decipher.
use grammer, and punctuation, and you'll prolly have better results getting better replys.

ok this is a problem i had with my probe injectors and a safcII , i tried to tune it my self and did not know what i was doing. and trust me the air / fuel ratio gauge will not work to tune a fuel injection car, it is more of a pretty light show . you need a wideband to tell you anything. or if you dont want to kill this little motor trying to learn ,go to a shop that knows about the emanage unit and has a dyno that will read air and fuel ratios, pay them for about 3-4 hrs and let them tune it. i did this with my probe injectors, and safcII , cost about 450.00 and i learned that at idle it was flooding in gas, but as it would increase in rpms and build boost it would settle down but at high rpm it woul lean out way to much for the boost i was trying to run. at that time i was trying to run 12psi. so we tuned it to run 8psi and it would run good at idle and at full boost it would richen upto about 14:7 . that would be a ok tune for the setup you got . if i where you i would call a tow truck and take it to a shop let them start to tune it . they well tell you what is going on. this is not a old muscle car that if you smell gas it is rich there is a little more to it. sorry for the mistake , when i said a 14:7 that was befor we tuned . as lagos pointed out it would blow your motor and you should try to run a 11-12 afr .sorry again i did not explain very well, and on a lighter note i did do some very bad typing in this , that was wrong of me.... he..he.. wont happen again.

pabel89, your post is hard to read. there is no fullstop, comas and so on. I don't even know when is your sentences complete. With plp hard to understand what you're trying to explain, how can plp help you to troubleshoot?

TRD94,
yeah, basically im having the same "issue" as you do. at idle it was running rich but lean out nicely to 11-12 ratio on boost. I was told its due to limitation on piggyback (im using emanage blue) but its ok with me

>yeah i am ok with it to but i think there is a little more my tuner might be able to adjust ... we will see when it gets warmer out right now it is body work time

Jesus Christ... some of you guys need to go back to school.

>

14.7 under boost will blow your motor. You should be aiming for anywhere between 11-12afr.

>
sorry that is my bad... you are right i was totally thinking of something else . boy i feel like a retard. it was a 12hr day at work and i was up way to late last night. and sorry for the bad typing. i will try to do better. sorry again.

ok i order wideband from ebay $300 freaking crazy...if i knew this setup was going to be so expensive ive would of gone with the 3sgte swap.ok now tht i got my wideband this what im planning to do: right now my car is in my driveway, what im a do is install the 3sgte map sensor,drive to my mechanic, im a install the intercooler to the turbo so it can start boosting then go one with the tuning from thier. anything wrong with tht let me kno should i get a tow truck?

well do you know what wideband you bought and why it was $300 as opposed to some cheaper ones out there

>

first of all, these should all be installed at the same time.

1) without it your car is not capable of reading boost properly
2) by leaving that off, that is how you destroy your turbo
3) a wideband is the one that reads your a/f ratio in numbers. anything else is useless.

Ok, first off.

WTF is your definition of choking? Is it:

A: Smells like gas because it is running far to rich

or

B: Lacking fuel because its lean with no tune.


Proper answer is B. Choking means you are lacking whats needed. However, it seems you are using A.


This is still irrelevant and refer to my last post in red. Install everything the way it should be, put the damn map sensor in and tow the damn car to the tuner.

the car is running like tht cuz it isnt tune, it feels like the car is running on fuel then in between air then fuel again.
