It seems like everyones preference of gauges in order of importance goes:

1)boost
2)egr
3)oil pressure

A turbo can blow your motor by forcing in more air w/o pumping enough fuel correct? So why shouldnt an air/fuel gauge be like #2 after boost?

 

the only air/fuel guage worth running is a wideband. autometer and the rest are jus a light show, and something for the girls to say "wow look at those pretty lights, i like how they go back and forth like that!"

 

LOL! Well my fiance is the only girl that rides in my car and it take more than a light show to impress her. Does everyone feel this way?

 

Most people here on honda-tech fell the a/f gauges are junk. They are deff not something that can be used for tuning but are NOT usless. They are kind of like dummy lights. If you have no fuel press gauge in your cabin and you are runing a vortec fmu or something elce that raises the fuel press to insane amounts of fuel I would NOT run with out the a/f gauge. This is the only way to tell if something goes wrong with the fuel.

 

But with a Hondata you dont think they are needed?

 

an egt can tell you the same thing as an AFR meter. (to an extent)

 

i've got boost, EGT, water, and fuel press.

 

a/f gauges are useless unless your running WOT, then the ecu is in open loop mode and doesnt correct all the time. I have an autometer a/f gauge and the its only usefull for ROUGH tuning.
An example, if I flored it froma stop in 3rd, the gauge would read rich but when Vtec kicked it it jumped to lean.
Thats about all there good for.

Some people with VAFC and SAFC units use the "blue wire mod" to monitor O2 sensor voltage via the AFC and make adjustments based on the readings (at WOT of course)....

 

could I hook up a regular A/F gauge to my AEM wideband? it has 0-1v and 0-5v outputs.

What gauge is this??? Im pretty sure you cant. Its either calibrated for a narrowband or a wideband.
