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 ???

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
