Stupid questions perhaps.. but I am curious..

Learning more as time goes by.. lol.. so now I am trying to figure out AEM Wideband gauges.

I assume that the AEM wideband basically monitors the Air/fuel mixture in the MKIII, but past that I am just wondering how you utilize the info. Does it protect the engine or just warn you if you are running rich or lean? Is it majorly useful for tuning and then just simply a monitor? I tried searching and just trying to wrap my head around this. I thought that on a 7MGTE, the AFM along with the ECU handle that all discreetly.. but then again, that could just make me sound like an idiot.

Anyone have a minute to give me an understandable explanation?

Thanks in advance!


Also.. what the heck is this 2-stepping. Looks like its simply a gimmick to get flames out of the exhaust, but it dont look healthy to me.. lol.

A wideband gauge will provide you with valuable information with any modified vehicle about the air-fuel mixture and provides accurate information when tuning your car. There are dangers with running to lean and to rich and this gauge will help you determine this. for an example I use this information i get from a wideband because i run an APEXi SAFC2 which is a device for tuning the air and fuel mixture and it lets me know if I need to make changes to my tune.
so yes, your assumption was basically correct.

A two step is the same (mostly) as a raised stall in an auto vehicle. Without making your head explode, it will basically give you boost off the line, instead of having to wait until higher RPM's for it to spool up. It can be switched on or off, so you don't sound like a popcorn maker everytime you stop.
