02 volt reader

[Ghostriderdsm]

Well first off, hello i'm new to the board. I'm from ontario canada.

Now I'm wondering about the 02 voltage reading.

When i'm WOT i get around .094-.096, Idle i'm at like .02-.013, When i shift i'll go to -.043 to -.012. Is it the higher + side the richer you are what are levels that i should be looking to be around.

Your 02v should cycle from about .2 to .7 at idle if it does not do this and stays at a relatively low voltage you are either running lean at idle and have a vacuum leak somewhere or your O2 sensor is bad. Also I hope all your settings on the SAFC are at 0 for the Hi and Lo maps since you still have the stock injectors and MAS.

setting are so on the s-afc
LOW
3000 -5
4000 -4
5000 -3
5500 -2
6000 -1
6500 0
7000 +1

HIGH is -1 off each

I would suggest resetting all of your settings to 0 across the board both Hi and Lo and see how that affects your O2v. Remember do not tune based on your O2v. It is not reliable for WOT tuning.

Do you have a logger?

Fill out your profile with your mods so that you don't have to post them every time.

Just did the profile.

Also i'm throwing a CEL because i have no 2nd O2 due to bigger exhaust.

I am not as familiar with 2g's as I am 1g's but I think most people just leave the 2nd O2 sensor plugged in and zip tie it up against the frame of the car. I think that keeps the ECU happy. 2g owners please back me up on this!?!? So, if you don't even have a sensor plugged in that would be a cause for your CEL on the 2nd O2 Sensor.

Did you try what I suggested?

 

[Ghostriderdsm]

NO change.. I'm thinking maybe a 02 sensor on it's way out? Would that suggest why i'm running rich aswell?

Like were talking 280-300 miles to a tank IF that

If you set the settings to 0 and your O2v didn't start to cycle at idle then yes it's probably on its way out. But 280-300 to a tank isn't bad either. My 1g gets 19mpg that's about 200-220 miles to the tank. Then again the 2g has a larger tank.

yah thats driving like old people f#$K tho. When i pound on it at the track i'm maybe looking at 120mile-150miles
