What is a wideband and what does it do and when should I buy one. My mods r agp fmic, intake, 3' exhaust, wastegate set at 16psi dropping down to 10, act clutch, nitrous intercooler sprayer, and downpipe.

 

A wideband is a gauge that uses a wideband o2 sensor to display your air/fuel ratio's.Before you change your stock boost levels you should get one.

 

yes, you have a wastegate and can 'play' with your boost levels. you definately need a way to monitor your a/f ratios.

 

What should b my a/f ratios

 

no more than around 11.5-11.7 at wot

 

so say that you have a wideband to monitor your a/f ratio so if it is runing rich or lean what are you suppose to do about that or does the the gauge take care of that for you and if i were to get one which would be a good one to get

 

if it's running rich you pull some fuel, if it's running lean you turn down the boost. the gauge doesn't do anything for you other than read your a/f's, you need a tuner to control fuel to tune properly.

 

"pull some fuel"? and what kind of wideband would you recomend and what kind of controler are th ones agp sells good because i live kinda close to them and it would be the easiest and cheapest way to go.

 

pull fuel, as in there isn't as much fuel going to your injectors.

the best on the market are the innovate and the aem. they're the two most common ones. the innovate is more expensive than the aem but it does more. as for a controller, a dtec fcor a safc-neo are the most common.
