now this probably belongs in the boost forum. ok. the general purpose behined a wide is to accrutely tell you a/f mixutre right. so basically a wideband gauge, bung, and sensor would be all you need to properly tune your car. do you really need all that other stuff to tune it. there is so many different wide bands to choose from. im going turbo and running around 6-8 psi is my goal. i was looking at dynotunenitrous.com's ad on kit to be used with a stock autometer gauge. this seems like it would be enough for me. anyone want to explain these more in detail?

a wideband is more accurate than the autometer a/f gauges because the autometer gauge just taps into the signal from your existing o2 sensor, which is a narrowband. what you see on those gauges is essentially garbage- a constantly varying ratio as the computer tries to fine tune the ratio. a wideband works independent of your car's computer, and gives a wider range of readings so you can properly tune a car with forced induction or serious engine work. and what do you mean by "all that other stuff" to tune it?
I picked up the LM-1 wideband kit (your first link to the LM-1's, I believe) due to the fact that its quite accurate and it has data logging capability. I have this so I can keep track of my a/f ratio while I drive and I can use those charts later to tune the engine. It's pretty useful but if you have other means then try something else. It just depends on what you want. Sorry I can't help you with the Autometer wideband hook-up, I've never even heard of this until now ('this' as in narrowband gauge made to take wideband readings). Seems ok I guess if all you need is a quick reading as you go and don't need to follow up on the data.
Blown.
basically im gonna use it to tune while i drive. i live in small town and can go play around and watch the reading and adjust from there. this is gonna be a second car so i have time to tune it and not have to be in a big hurry. i have an adjustable fpr and fmu plus bigger injectors that im putting in.

I believe if you have an FMU, you can only adjust under the hood, not while driving or in cabin.
What other questions did you have?
Also, I plan on getting a Zeitronix (
www.zeitronix.com) Wideband. You can use it through a laptop and features Boost, A/F and EGT monitoring or you can buy an LCD Display for a bit more cash with the kit.

glad to hear from you again njhk. i know i cant adjust from in the cabin but i can use the wideband to tell my mixture. stop and turn it up or down and then try it again.

It's no problem. I figured that's what you were going to do but the way you worded sounded weird.

Can't you just use the long term trim to see if you are running too lean or rich?
Not really, long term fuel trim may give you an indication of rich/lean over time, but you are usually more interested in your instantanious a/f ratio. Plus the fuel trims are done by the pcm to try to maintain a 14.7:1, depending on what kind of modifications you're doing, you may wish to be richer than that, and its hard to determine based on fuel trim alone.

Buy stuff from CarCustoms Ebay! Won't be disappointed!
im gonna jack my own thread. what is a good a/f ratio for my car at aroun 6-8 pds. or does it matter how much boost im running as to what the ratio is? shifted is that 14:7:1 what i should shoot for?
"IF YOU PERSIST IN DOING WHAT YOU HAVE ALWAYS DONE .....

that's too high. i'm sorry but i work with one of the best tuning artists in the midwest and no turbo car should go above 12.2:1 AFR in boost. We tune cars for 11.5:1 at WOT, peak boost, max timing.
I was a retard, and now I'm permanently banned.
