hmmm A/F guage not reading right

[h22sparkle]

Okay people heres my next problem or ponder on something. Now i have a autometer a/f ratio guage it reads lean then it goes out on its own now does this guage rely off the o2 as well as the catylic converter to give it a more suitible reading?

It only gets readings off the O2 sensor, there's no feed from the cat.

An A/F gauge on the stock O2 sensor is just a lightshow. You need a wideband to know anything other than that there's air and gas pumping through the engine.

yes I used to have one of those light shows too. lol. it really is pretty pointless. If anything I would go with an egt gauge.

ive had this to it is not accurate at all they do make wideband ones i forget the site but have seen them. if you want a real a/f guage get one of them hale meaters i thinks tahts what its called its like a black box

An AEM UEGO Wideband with gauge [with center digital display] can be had for $500 now. Kudos to AEM, it's a great innovation on a great product.

So where do you hook the A/F sensor into?

[Accord SiR]

You would connect it to the o2 signal wire either at the ecu or the near the o2 sensor. Don't remember which color wire the o2 signal wire is though.
