Please dont bash me. I just wanted to know if I could piece together a kit for less that 500 dollars. I got everything except the wideband.

Is it possible to get a car tuned without a wideband O2?? I recently pieced together a turbo kit and I ran out of money before I could order the wideband. Im running a walbro 255 high flow with stock injectors, cause I only want to run 8 to 10 pounds. I have a SAFC 2 put in and set to gradually raise the fuel when boosting. Im new to all this tuning stuff. I also have a un-named FMU (Got it from a turbo Neon).

I guess what Im trying to get at is, is there anyone near Harrisburg Pa that knows a lot about tuning, and that could help me out. Right now my car is running like sh*t, but there are no codes. When I lightly press the accelerator the car boosts well (5pounds), but when I press on it normally the car sputters like its getting no fuel, or too much. IDK, I just need some help.

I forgot to mention that I have a Missing Link. And besides the 200 dollar SFMU, what could I use?

Ok, Im going to park the car til I get a "name brand" FMU. Looks like my car will be sitting for awhile. Thanks.

Luis.

do you have a fuel pressure gauge or any way to monitor if in fact your rail pressures are rising when you get into boost?
could be that the fmu you have now is faulty or *may* be hooked up wrong so that it wont rise propperly.
or (contrary to my friend above ) the fmu could be just fine and you are hitting cut because your missing link is fubared, which is why more and more people here are switching to a FCD instead.
now THAT piece you can get cheap from people here.

Well I followed everything that is said on the SAFC tuning guide on here by RS_Guy, and now it takes my car a couple times to turn over and it really idles like crap and runs like crap. I do not have an open empty road that I could tune it like the guide said to. So now Im completely confused, and I need some hands on help ASAP. I could pay someone to look at it, I just want it driveable again. Im desperate here. LMK

Luis.

take all that crap off your car....you don't seem to know what your doing, and u don't know how to figure out what ur doing by searching....

you could piece 1 together, but it would be crap, so why would u want to?

you say ur desperate, which prolly means u need this car reliable...so take all the crap u tried to put on it off..im really surprised the thread went on this long...after all it did start out with "don't bash me guys"

look luis , its called search function. if you want to boost a car , u need more then 500 bux, and in your case, you need daily diver b/c uve now screwed ur car over so bad it wont drive or idle normally.

Its not my daily driver. Also I have pieced together a turbo kit before on my buddy's car a long time ago. Last that I heard (he moved outta state) the car is running great. He was really good with electronics and understanding them. The only thing I need help on is this air to fuel ratio crap, and get rid of this fuel cut.

Luis.

Yes I have the pin outs done correctly, and I set up the AFC just like the AFC guide on this site. Im going to try to do set it up again, and read the guide over again and see if I missed something. That how to should at least get the car driveable. That way I could try to get it to a dyno or something. According to the how to, your supposed to hold the accelerator to a certain rpm and adjust from there, but I dont have an empty open road and also dont really have someone that could sit there and help me out.

never said i was a tuning expert...

as for the ?, i thought it was newbish, it didn't seem like he had a good grasp on "tuning" (not saying i know all either), but theres more then just the A/F crap, what bout EGT? do you plan on monitoring that? sorry, it just bothers me how were all do it right or not at all around here, and then this sorta post pops up. i know were all on turbo budgets, but 500$, come on lol..neways..im not understanding why the advice is to continue using an SAFC? i thought it was general consensus that they suck. if your running a SFMU, why not get #30's, and eliminate the source problem (the SAFC). From my understanding and searching on here, they cause way more problems then they fix..so sorry if i hurt some ones butt..
Imo, since u have the Missing link, get an SFMU, get #30s, and sell the SAFC. that way ur good to go for the 8 psi u want to run.

Ok ok....so what exactly do you guys suggest I do / get?

I did happen to find a dyno thats around 10mins from my house, should I just try that? I tried that RRE website on the AFC and I put in the setting that has pretty much all stock 2gn turbo Eclipse w a T25. The car idles fine now (steady 900), but when I accelerate, even just a little, the car shutters like it starving for fuel or its getting too much fuel. IDK, I think Ill just let it sit til I can get an appointment to dyno tune it. Unless there are different suggestions. lmk

Luis

I'd start by removing the safc for now. Your current setup doesn't really need one. If you still have problems after its removed then you know its something else.. You just need to narrow down the places that could be an issue. And get a real electronic FCD.. They are cheap and much more reliable than the missing link

Since yuor using stock injectors, remove the SAFC. its most likely what your issue is. Your high settings are off. Either "Zero" out the high and lo settings or remove it.

Terry

How exactly do you "zero out" the afc, do you mean go to the Initalization menu? Sorry my afc didnt come with instructions. lol.

Also I have a walbro 255 high flow in, should I go back to the stock fuel pump? Do you think that would flow enough? I only want to boost 8 pounds max til I can build up my other block with forged internals.

So right now Im thinking of taking out or zeroing the afc, Im also going to put on my stock fuel pump, and see if there are any other issues. Im going to be purchasing a FCD sensor, and getting rid of my missing link.

Am I missing anything? I guess what Im really trying to ask is what is needed to run 8 pounds of boost, safely?

Thanks
Luis

Leave your pump in, stay with the 12:1 FMU you have. LEave the missing link in since you already bought it, just remember to clean it when you do oil changes.

I am real rusty on the SAFC but if you press the arrows it should take you to the RPM points If i recall (graphic display). Just move to each RPM point and set it at Zero or right in the middle. You have two graphs, one for the high throttle setting and one for the low settings. Zero both of them out. If you can figure it out, you can download the instructions from Apexi or I can look it up for you.

Terry

Alright heres an update. I zero'd out the SAFC 2 like starturbo said to. I kept the Walbro in and my FMU. I started the car and it seemed to idle fine, but when I pushed the accelerator, the same thing happens. The car really struggles in the 2-2.5rpm, and the 4-4.5rpm.

Could there be something wrong with the FMU?? Also my walbro fuel pump has a loud steady humming sound, is that normal?? I had one in my 94 Talon ESI and I dont remember it being so loud.

Tell you guys what, Im going to try to get a video of what my car is doing tonight or tomorrow, and then yall could tell me whats up, maybe.

Luis

Well I tried recording it last night, and when I went to view it on my computer, the sound kept cutting out and the picture was blurry. I guess my camera is taking a shit. Ill try again tonight to see if I can get it to work.

I turned the car on to go fill up, and when I pushed the accelerator the car really bogged down. Im guessing way to much fuel. Im going to try to adjust the FMU, to see if that helps any. So when I lightly press on the gas the car sputters, does that mean lean?? And when I press it normally the car boggs, to rich?? My fuel curve seems to be all jacked up.

Luis.

I tried adjusting the FMU, and the car seemed to run a little better, but when I took it out for a spin it doesnt want to boost. It sounds like it but theres no pull at all. It still wants to sputter around the 2-3.5 rpm, but when I hit the gas it doesnt bog down too much.

Ive been trying to call my so called friend that put together my kit, and hes no where to be found and he wont answer my phone calls. I think he knows that Im pissed off and that maybe he put something on the wrong way. Is there anyone on this forum thats in or near Harrisburg Pa?? Im up shits creek without a paddle here. Just need someone that can look over my setup.

Luis <---PISSED OFF!!!

Hey man, wanted to know what if you found your problem. I live in york and would be happy to help any way that I can.. Im nowhere near as good as most off the guys on here but my car runs pretty good I think with out actually being tuned. So let me know if theres anything I can do to help and its kinda nice to know that theres someone close to ya thats on the forums

Doing a 850 dollar turbo install on my 420a, is that okay with you? you can really bring down the price if you have months of sitting and emailing people on forums, checking for sale posts and comparing prices. plus it helps that i am getting my megasquirt for 150 bucks. so if the guy says he spent 500 dollars on the turbo set up, what if they are all great parts, and he just found some people who just had it laying around?

I dont know what you do for a living, but I cant afford a 3000 dollar kit, or even a 1500 kit. I would love to just go out and buy a kit, but I just cant. I had to make mine and cheaply, so thats my life. Im going to make sure it runs really good, and keep up with the maintenance.

Luis

Its just taking your time man, who says you have to boost your car right now? Hell its taken me 2.5 years just to almost be turbo'd but I now have all the supporting stuff to go along with boost. Just take your time and make the right purchase the first time or you will end up buying parts twice.

I am taking my time, I bought this kit of a Turbo'd Neon really cheap. They pretty much have the same setup except for a few things, but Im getting by. Slowly but surely Im going to get this car on the road again. I just have to get the dam fuel issue taken care of.

Hey Mike I put in a bid on a Vortech FMU, so hopefully this would be the last part that I purchase.

Hey Luis...so I see you're finally trying to get the car boosted. IMO, just keep it simple with the FMU 12:1, stock injectors and the 255 Walbro. Definitely lose the SAFC because you don't need it. This setup is fool proof and should require no tuning. Hit me up if you need help, since I'm live closer to you now. I also have a Votech FMU and FMIC w/piping that I bet you could use.

Hey Ron what up?? Yup Im finally boosting my car. I have ordered everything needed except for the 12:1 Vortech FMU. You have one for me?? Im sending you a PM

Now is it ok to leave the SAFC in just incase I get bigger injectors, or just take it out completely?? Right now I have it zero'd out, also set to 4cyl with the up arrow, 7 in 7 out, karman and I believe thats it. LMK anyone.

Thanks
Luis

Karman is the wrong sensor type.

Pull it out.

Alrighty then, Im going to take it out tonight. Kinda sucks cause I soldered the wires.

What do you mean Karman is the wrong setting? The safc wont let me change it.

Luis

I tried changing it to 6 but then the car started bucking and eventually die. SO I left it at 7in 7out.
