Air/Fuel Meter

There was a user in this forum that gave a link to his online rotary shop... I found a cheap (approx $39.95) digital air/fuel meter on that site... I left the shop and never found my way back... If anyone knows what the link is or a similar link, it would be greatly appreciated if it where posted again in this thread... I tried searching for it for about a month now... You would be surprised at how many links come up for Air/Fuel... Or maybe not...

Whats the difference between the two...? I just get crappy gas mileage and I think that an air/fuel adjustment may be the key... When I bought the car it got about 6.5 mpg... It is now to 12.75... So anyway... I am rambling... What is the difference? I just want something for a one or two time use so that I can adjust it and be done...

using a narrow band a/f gauge is kinda like a deaf guy going to a rock show, or a blind guy "watching" a striper. you get the idea but the majority of the show is lost to you. get it? like the rest have said narrow band a/f gauge = shat

widebands are cool but expensive but if you have one you own if you want to do any tunning on your car yourself you have to have one

You gotta love the uniformed responses here...

It's not "useless".
The AFR gauge will tell you if you're grossly lean or grossly rich.
Don't try to fine-tune with it.
It will tell you if you're in trouble either way.

With an EGT gauge and an AFR gauge, I can tune both fuel and ignition, while the wide-band guys are scratching their heads.
Useless?
Hardly...

BTW, Summit Racing sells their version for under $30.

Like Ted said a narrow works fine for letting you know if you're too rich, too lean or in closed loop. BTW, I've been running a narrow band for 6 years. To me it's just basic protection like any other gauges you would add like water temp and oil temp/pressure. If you are tuning your own car a wide band is prefered by quite a few people.
