ANY BUYING/SELLING IN THIS FORUM WILL RESULT IN AN INSTANT BAN!

Read the rules: http://www.cb7tuner.com/vbb/showthread.php?t=43956

Myself, and the other mods have been very nice and lenient with the rules. We have been deleting threads, and giving out warnings. Some members didn't get the clue and re-posted over and over... Now ANY member buying or selling in this section will be banned... No IF's AND's or BUT's.

Beginner Forum Rules - EVERYBODY read! (old and new members alike!)

Beginners start here. Once you have 30 worthwhile posts (off topic doesn't count) you may post outside of the Beginner forums. Any "whoring" (posting simply to raise your post count) will return your count to 0, or result in a ban.

These are the rules. Read them. Live by them.

1) Absolutely NO flaming! "Flaming" is an outright attack on a member. ALL questions are encouraged to be asked here, no matter how basic. Members with over 30 posts will be subject to a ONE WEEK ban if caught flaming in this forum (and yes, moderators can read deleted posts). Members with under 30 posts will be subject to a ONE DAY ban.

2) Use appropriate language. Racial or sexual slurs will not be tolerated. A ban will be issued at the discretion of the cb7tuner.com staff.

3) No items may be sold in the Beginner forums. Any "for sale" threads will be deleted.

4) Temporarily banned members will be PERMANTLY banned if they are found posting on another account.

The rules can and will be added to. Any updates will be marked in the title.

The rules for the overall forum can be found here:

Read them. You will be expected to follow them.

    air/fuel ratio

    i have a air/fuel ratio gauge i am looking for the signal wire on the 02 sensor. It as 2 white wire,1 Grey wire and 1 black what wire is the signal wire? Thanks for the help

    To read properly with an A/F gauge, you need a wideband O2 sensor and controller. If you hook the gauge up to a narrowband sensor (standard 4 wire unit) the readings will jump all over the place and it will be pretty much useless.

      Yea, it's best to have a wideband, but some people have hooked it up to their regular o2 sensor, and got readings? Not sure if they were correct readings, but...the needles moved I guess. If you're wondering the wire, it's the white one. Which white one? No idea. Maybe you can get some info from these. Here's a few links of kids who've thrown these on...

          the only "accurate" reading ur probably gonna get is when u come to a stop. or in neutral.
