o2 not ready

[Icyu11725]

Recently bought a 1996 eclipse gsx. With a full turboback exhaust, with no cat. Right now when i scan the car it says front o2 not ready, cat not ready, rear o2 not ready, egr not ready. I need these all to say ready. I kno to trick the comp. I have a cat i need to space the rear, but how do i get the front and rear o2 sensors to say ready? What causes this?

Well, a faulty sensor could be the problem to start. Are the emissions under the hood still there? I'm guessing they are eliminated seeing you have v3 of Link. Are you using a wideband in narrowband simulation or is the stock o2 sensor up front?

Are you getting a CEL or are the readiness monitors just not "ready" for emissions testings?

Im not getting any cel codes. Its just saying not ready. But my car is running very rich but i have 750 injectors with a big 16g turbo. So i was wondering if my o2 is bad. But my mechanic failed me becuause i have to many not ready monitors.

Ill hook up my laptop and take a screen shot of the readiness monitors. Give me 20 minutes

Im really sorry, im really new to this, how do i get the log?

There should be a button once you open link that says "Capture log". Once you capture it (and then stop it after a while), it will autosave to a folder inside the link folder structure. Then just make a post, click Go Advanced, and upload it like you would a picture.

ok got it, doing it now, but now my car is idling high =/.. ugh this car is just a headache.



edit: how long do you want me to log it for? until it warms up??

here is the log ran it for about 2 minutes.

From the log, it looks like you may have a messed up front o2 sensor, if someone didn't put a wideband in the front spot.

Wow, that log has all kinds of messed up stuff in it. Ugh. Did the person before you actually get it tuned? Just trying to figure out where to tell you to start.

supposdly he said he had it tuned from a shop. and what do u mean wideband? if youd like snowborder i can talk over the phone if you'd like might be a little easier. just pm me if you'd like

Well, if you don't know what one is and the previous owner didn't mention one, then it probably doesn't have one. Then you need a new front o2 sensor. Although, it's odd that it's stuck in the middle of the range and not at/around 0v like it usually does.

Interesting that it was tuned by a shop.

it needs alot of work before i start playing around with the tune and stuff, thats why i really need some help


edit: btw should i buy a stock o2 sensor? or should i buy a universal wideband o2 sensor?
