I know getting a narrowband A/F Gauge is almost buying it for a light show. But on the other hand a Wideband A/F Gauge is it really worth it for our cars or should I save the $300+ dollars on getting one? I have seen a lot of debates on different boards but I just wanted to see what you all think Wideband A/F worth it or not worth it?

 

If you plan on tuning a car, you need a wideband. The reason being is that the stock A/F reader only reads if you are above or below the desired stock A/F ratio. A wideband will allow you to read the true ratio of air to fuel.

However, if you don't know how to tune, or plan on have a shop do it for you... you really don't need it. That is, unless you are seriously pushing the limits of the car and you want to keep a watchful eye to make sure nothing breaks in the engine.

Which one is the best is a another debate. Just my .02 cents.

 

The WBO2 is really good if you have the ability to actually modify the fuel delivery.

If not... then it will just tell you when to back off..

 

I have a WEGO wideband and I like it alot.
