Wide-band preliminary results, EFI guys must read!, Narrow-band sucks!!!! Options

10.5 AFR!! (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif) That’s what I was running!

I was tuning with a Haltech AF-30 narrow band and they are “supposed” to be pretty good. Since I was running so rich before, now my gas mileage should go up and the throttle seems way crisper. I’ll post my fuel values later (before and after) once I’ve fine-tuned them a bit better.

Wide band users! If you’re running an exhaust extension tube, your lambda is not getting hot enough for an accurate reading! Even if it is a heated unit…mine is.
The WMS wideband has an LED that lights up when it hot enough…It took almost 10 min. at the “Y” in my Ansa exhaust (with SSI’s) before I had a green “hot enough” LED. A header would most likely heat up way faster.

Is it just me?  I have no idea what any of this means?   (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif) Wide band - is that like my cable with Comcast? (IMG:http://www.914world.com/bbs2/html/emoticons/lol2.gif)   English translation - or better yet - the "For Dummies" version for the rest of us.

in very simple terms:

the narrow band is like a regular light switch, on/off (rich or lean)

the wide band is more like a rheostat potentiometer light switch, many variables (it's tell you how rich or how lean you are)
