turbo wit no O2 sensor???
 
can i do that?
i dont have a swnpipe for my turbo yet but can i run it without. plan was to take it to the shope so they could run a new exhaust for me?

and the hole in the back of the vavle cover that use to go to the intake,
do i just put a brether filter on that?

oh, you're just going to drive it to the exhaust shop, and they're gonna weld bungs in for your 02? if so, yeah, that will be fine, the car will start and should run fine, especially for just a short distance. yeah, you can just put a breater filter on the nipple on the valve cover, or you can make a catch can down the road, but a breather is fine for now.

naw
there isn't a pipe at all!
just the exhuast housing
i was gonna try to put a pipe on there til i go the shop so the exhaust fumes would at least go towards the ground.

yeah, i know, that's what i meant, but when they make your exhaust, they're gonna weld bungs in, so you are gonna have your 02 sensor, you'll just be driving to the exhaust shop with no exhaust/02's? if so, that should be fine, but yeah, just make sure you don't have any wires or plastic too close to the housing where the exhaust can melt them.....

assuiming its a honda (i only know about hondas) the car is gonna drive like ----. if u plan to just go to the muffler shop, no prob, but if intend to leave it like that for a few days, expect the car to be very slugglish.

coo

why is the car goin to be sluggish?

people say that, but i didn't have my 02 sensor hooked up on my old integra and it ran perfect, no difference at all (except the cel :-\)

well generally, when you have a cel on, there is obviously a problem with one of your sensors, so the ecu usually goes in "limp" mode, which basically, it just runs rich (which makes the car lack power), and doesn't let you rev over 4k usually, this is basically just a safety precaution, but i've never known it to go in "limp" mode for an 02 :-\

Re:turbo wit no O2 sensor???
 
wow
i dont think mine has gone into limp mode..(yet:()
i have two sensors and only had one hooked up all least year because of my hi flow cat
i was defintely rev pass 4K
and was near it when lauching at the track
i hope it dowsn't go crazy now that ther is one at all

it'll be fine man, just go get that damn exhaust put on so you can post all your pics ;D

Re:turbo wit no O2 sensor???
 
well the oil is in and it's runnin
loud as ---- with out a downpipe
finishing up some toher stuff and i;'ll have pics up in a couple days

just lettin yoah know the install was succesfull

I recently blew a fuse messing with my o2, and was getting cels for both sensors (heater circuit). The car ran fine. Don't worry about it.

Re:turbo wit no O2 sensor???
 
my d16a9 engine from europe does not have an o2 sensor, i cant rev easily past 4k rpm, but i can if i literally stamp on the pedal. does this mean my ECU has gone into limp mode...
do all turbo cars require a o2 sensor?

thanks :)

Re:turbo wit no O2 sensor???
 
ok listen to a little story i have to tell the no O2 sensor user no o2 sensor the ECU picks up a lean and rich exhaust reading meaning the ecu will then pump more fuel when lean and less fuel when rich . meaning that the ecu cannot pick up the correct and best fuel,spark and air mixture not very good when you are trying to tune your car .... put the o2 sensor on and run the car a CEL is just gonna piss u off cause a CEL can mean more than just an o2 sensor going bad... good luck

Your good to go without and o2 sensor... I have had a code 41 (primary o2 sensor) on my car for a few months and I have benn driving my car a lot. I guess I have noticed recently it has been a little sluggish maybe, but she still revs to redline like a champ. ;D

I do have a new o2 sensor, but I am waiting until I go turbo to stick it in.

Re:turbo wit no O2 sensor???
 
QUESTION????

if im hookin u a SAFC wit some DSM's
would it even mater what the O2 sensors read since i'll be
controlling how much fuel to mix?

Quote by TurboEF9:
AFC Hack - The AFC hack refers to a MAP sensor input scaling device (AFC) "hacking" the signal to your ECU and fooling it into thinking that it is not seeing positive manifold pressure. These are normally small electronic devices connected in-line with your ECU. Some more elaborate devices, such as A'pexi's V/S-AFC, SMC, and so forth, accomplish the same thing, but have the feature of being able to tune a specific percentage of "cut" at designated RPM increments. How does this work as a management solution? As positive manifold pressure builds, the MAP sensor sends a voltage signal to the ECU. This signal, if above ~3.1volts on a stock Honda MAP sensor, will cause the ECU to "shutdown" and go into limp mode, rendering your vehicle inoperable until it is turned off and restarted. The AFC intercepts this signal and scales it by a user-defined amount. This scaling allows positive manifold pressure to build while keeping the ECU happy. Fuel compensation for this setup is done by installing larger injectors. These higher flowing injectors allow more fuel to flow through during the same pulse duration to compensate for MAP signal scaling (which decreases fuel flow). No fuel pressure regulator is needed. No upgraded fuel pump should be required. This setup is normally god for ~10psi.

even with the afc the ecu still corrects values based on o2 feedback during cruising/part throttle operation.
