A/F gauge help !!

[johnnyluvchx]

Greetings all, I am about to install a autometer cobalt narrow band A/F gauge on my car. does anybody know if it is better to tap the purple/green wire on the first pin on the pcm, or the o2 sensor before the catalytic converter. any help would be great. please let me know the pro's and con's to each.thanks for any info in advance.

are you running a power adder? or can you weld a bung into your exhaust? i purchased the o2 sensor kit for that gauge, and it works perfectly, i did not wanna tap my pcm. . just in case i screwed something up.

A/F Gauge assistance.

I am thinking about doing the same on my car, but not sure where to buy the gauges from, or which gauges to choose. Where did you purchase that kit for you gauges? Got a link? Sounds like a simple fix. Thanks.

appreciate the help. plan on doing the install myself, doesnt seem hard at from what i have read. any sugguestions on how to go about it or easiet way to do it, as far as running the gauge wires goes keeping a clean appearance?

the best piece of advice i can give, is there is a grey plug under your console that has a 12 volt ignition wire in it, splice into that

could you be a little more specific about what wire you are using? I am about to add gauges to my car too and have enough trouble wiring things up, lol.

I am also installing a narrow band a/f guage by autometer. One thing I'm doing is welding a bung in the center of the cross over pipe so it will monitor both sides instead of just one bank. It should read both sides and then avg it out. JMO

hmm, i will see if i can see under there, but its all covered now, but you can use a test light to identify it.

In case your not already away….get ready for the narrow band light show. Really, a narrow band AFR gauge won't allow you to do any tuning, and wont give you any usefull unformation that you don't already know. They are IMHO a complete waste of money. I'm not trying to rain on anyone's parade…but rather trying to help those from making a purchase they will regret later.

I saw this and was going to just pass it over in order to not offend any one. However I have to agree the cobalt narrow band is simply a light show as mentioned above.. You can't tune off of it and it doesn't supply any hard data.

The route to go is a wideband, they are ungodly expensive gauges for a reason.

If your tuner is worth his weight, no need for a wideband unless you will physically be datalogging and tuning your own car on the fly.

Outside of that, if your going through with the install of this narrow band, Do as previously mentioned, punch a hole in the exhaust and weld in a o2 bung for a clean install. If you ever hit the dyno, they can use that location for their wideband hook up.
