please let me know i am about to put some gauges in my 01 s/c silverado!

 

They will tell you if you have a lazy 02. Only the one its connected to. They will tell you if you are running extremely lean or rich. They will not tell you what your A/F is.

 

Most guys say that they are pointless. BUT, I have a basic narrow band gauge and when my nitrous was acting funny it would tell me that it was going lean. A cheap narrow band gauge saved my motor.

With a narrow band you CAN NOT target a specific A/F ratio but you can use it as a tuning tool (but then again most of the guys here dont play much with a carburetor where the tuning is done with a screw driver and not a lap top)

 

It's a nice light show, but I wish I wouldn't have wasted money on mine.

 

What about the wideband stuff. anyone ever use these, or have one to recomend? LIke the aem?

 

Beautiful display of magnificent lights seeming to dance with the lope of my cam, but the only usefullness of the guage is for filling a hole in the pod and to show extreme rich or lean condition.

 

I have the AEM unit but have not installed it yet.

IMO the non- 5volt units are not worth the money and effort to install them. It's better to just save money and get a real unit and install it in the right location.

 

Narrow band = $35.oo
Wide band = $200.oo (or more)
When I spray nitrous the lights on my cheap narrow band always do the same thing. If they do something different then something is wrong. A narrow band showed me that there was a something wrong with my dry shot before it manifested its self in a more expensive way.

A wide band is better but a narrow band does have its uses. And remember people have been tuning the internal combustion engine for over 100 years, the wide band is relatively new.

 

They were not doing it with a narrow band sensor though. They were reading plugs and listening for knock.

Not saying the unit doesn't work. It just doesn't work well and leads noobs to misplaced confidence.

 

I have a Air/Fuel gauge but it reads in millivolts. I always read were people said that they were pointless and way off and compared to a wideband yeah they arent as accurate but they arent pointless. I wouldnt buy one of the Christmas tree ones but I liek the one I have. The closer you get to WOT the more accurate they are and thats all I need it for is at WOT when spraying since my n02 doesnt activate untill WOT. Here is the one I have
