I installed one but i do think im getting the right reading and im not going to lean it out just based on this gauge. The gauge reads 2-3 greens lights when idol, then 3-4 greens when wop. Is this right or is my o2 sensor done??? The guage dosnt pulse at all like i hear it should do. I go instructions but jsut wanted to know what you guys think?
thanks

from what I have read (i dont have one) they are NOT accurate.

 

It is using your narrowband 02. That means it only tells you if it is rich or lean. They are nothing to try to tune with.

 

yea ... there jus another flashing LED .... IMO... unless you have a what i thought was called a "Wideband O2" meter ... for acurate tuning...

 

with your stock o2 sensor, it might as well be a light bulb. because thats all it reads, on or off. it only reads rich, or not rich. there is no inbetween..

 

its a great light show, thats about it. get an egt guage and a five wire o2 with a/f ratio if you wnat somthing to work.

 

its just flashing lights and nothing more.

 

ha....mine stays in the green when i'm driving and when i start to slow down to come to a complete stop, it goes to the red section. don't go by what this type of guage reads.

why dont u just get a wideband for $300?

A/F guage is pretty much worthless.

 

first make sure you have your purple wire from the guage hooked up to the right wire off the O2 sensor. it should be the white wire or signal high wire. i don't know what your car has OBD 1 or OBD 2 but it should be hooked up on the first O2 sensor that the exhuast gasses will hit first in this case it should be on the header.

 

Without a wideband, you may be able to watch what is happening in the small area that your stock 02 sensor reads (0-1v) but a wideband reads 5 times that (0-5v).

 

not accurate like a wideband is...

 

but then without decent mods and some dyno tyme.. wideband still isn't really even needed

As far as the A/F lightshow you have....I wouldn't bet MY motor on that.
