Does anyone know if a four gas analyzer is really any differant than a wide band O2 ? I dont want to go hog wild buying all these new gadgets If I have things on the shelf here that will work. I would think I could tune WOT just fine with it but then again Im a newbie to this tuning thing. Any Ideas or imput would be great. Thanks in advance

 

They are different and do provide more information. However, if your only concern is only to tune WOT, a WB is adequate.

 

Sorry I didnt make it clear I have a 4 gas but no wideband. The wide band would be a redundant purchase I guess. Thanks for the reply and sorry for posting this question in the wrong area . Im new to this site and tuning.
