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.

Mark/Herb,
This is funny. I tuned with narrow-band to get things roughted in before getting my LM-1 wideband. Guess what. My narrow-band tuned AFR was about 10.5. That lambda curve sure is steep. Wideband rocks. They'd sell more of them if instead of sighting the technical aspects they just said "Buy this. It will fix your AFR, but more importantly it will save your marriage, your relationship with your kids, keep you from losing your job, and help you avoid being institutionalized."
