whats a good wideband to buy?

 

aem hands down.

 

Cheap = DIY WB from 14point7.com

Best = auto meter or a LM2?

 

ima do the autometer from summit... http://www.summitracing.com/parts/AVM-30-4100/

 

Thats not an autometer gauge, it's an AEM
what is the difference between a wideband a\f gauge and the cheaper (narrow)band ones ?
accuracy?? I think wide band o2 sensors have five wires and older narrowband ones have four ???

 

oh crap wrong one... lol... wait but i was told this was a good one also for the price...

 

Wideband allows you to track your a/f ratios over a wide rang (10.0:1 all the way to something like 19.9?:1) while narrow band only allows you to see open loop/closed loop (so pretty much 14.7 is stoich anything under that is rich, anything above is lean)
NB = stock cars to see if your in open loop/closed loop

WB = used for tuning and tells you your exact A/F ratio

 

ok so this is a wideband im getting correct?

 

Yes it is, not sure if it comes with the sensor or not in that kit
