i have seen people upgrading their wideband02 sensor. what does this do? and what is so benefical about this product?

another question is about the fuel cut defender, what does that to and also what is benefical about it?

 

Well I think you should post your mods so we can tell you if you should worry about it. I would say unless you are above stage 4 don't worry about either. In that you shouldn't be hitting fuel cut if you are tuned properly and wideband 02 I would assume your talking about a gauge. SO that just shows you your a/f ratio just to keep things in check. Im sure someone will chime in with the old "do a search noob" but don't get discouraged And we can always take this to pm so you don't get that

 

k thx, and by stage 4 what do you mean? since diff company offer diff stages.

 

well what i mean is anything past a bolt on turbo and supporting mods. What mods do you have so i can better help you. While you may not need a fuel cut defender at a certain point a a/f gauge isnt a bad idea

 

well currently i only have a ecutek and a catback exhaust, but i saw somone that lives around me with a sti and he is only running a TBE, WB02, and Fuel cut defender, and MBC, and ran a 12.8 at bandimere which is like 6500 above sea level, thats why i was wondering why he went with wb02 and fuel cut.

 

he has a boost controller.. That is the problem. WHen you are tuned using ecuteck it should take care of the problems that he has. THere is no reason for you to have either if you were tuned correctly. Then again i dont live at thoughs altitudes so consolt your tuner for further assurance.
