Im looking into getting one of these and wanted to know what is the best brand to get? I plan on putting it on my pillar so it would have to be that size, etc. Thanks.

 

Are you planning on buying one of the gauges that uses your stock narrow-band O2 sensors?

If so, save your money. During normal driving the gauge will bounce rapidly back and forth between rich and lean, responding to the PCM's closed loop fueling strategy. At WOT, it will move to "rich". If you are running lean enough at WOT for it to move to "lean", its probably too late to save it. The only useful info you will get from the gauge will be whether or not the O2 sensor its hooked up to is working.

On the other hand, if you plan to buy a wide-band unit, including controller, wide-band sensor and a display, look at the FAST dual band, the LM1 from Innovate Motorsports, or the Altronics O2 Alert. A dual-band setup is going to run you $500-750.

 

AEM wideband $180 on ebay.

 

Same here, works great and can log data with Datamaster for tuning.

 

Who on ebay specifically did you all buy them from? Also, My computer is obd2 and didnt know if datamaster worked with that. What is the easiest/cheapest/best tuner program for obd2? I was thinking about tunerpro rt. I read up on an old thread and it seemed pretty decent. I know this should go under tuning but oh well. Thanks guys.

 

Got mine from http://stores.ebay.com/MK3TUNER.

 

Many believe the current best tuning program is Jet Dynamic Spectrum Tuner. You can get it in lots of places. I personally own LT1Edit, and it su#ks on so many levels I cannot begin to say. AFAIK, those are your choices.
You will need to find an fbody OBDII data collection package. I use AutoTap. It is expensive but does a decent job, except for one critical deficiency: It does not allow external inputs, so you cannot easily plug your wideband into it for time synchronization.

 

I plan on getting the AutoMeter Phantom 5770 wideband. I believe the release date is sometime this month.
