I have a few questions regarding my AEM Uego Wideband.
This is the first wideband Ive owned so I do not know if this is normal behaviour for a wideband.

First, when I installed it I also installed a boost gauge so I connected both gauge's power wire together, and connected it to a 12v source.

Second, maintaining a steady speed, is it normal for the wideband to read from (for example) 14.5-15.3 and traveling this much?

I also noticed at idle, it reads 12.9-13.0 for about 40 seconds then the afr raises to about 15.

 

You aren't tuned yet I am assuming!

 

Nope not tuned...

Another question...

My boost gauge, under light driving only hits 10psi.
but under heavy driving (WOT) it will read 21.
normal also?

 

yup everything sounds normal...the wideband will move quite a bit when just crusing along, but it will remain within 1 full point usually.

 

sounds perfectly normal. it bounces around and cruise and idle because the car is running off a narrow band which oscillates around stoich. (14.7)

 

Sounds great, thanks. Im a newbie when it comes to Turbocharged vehicles and widebands

 

My Eclipse is the same way. If you actually log the narrowband O2 sensors you'll see why the ECU is up and down. Those things bounce all over the place.

 

For being a newbie, thats quite a mod list you have in your signature.

 

Mine use to hit 23 psi, but after all the mods (FMIC, Pipes, Turboback), it dropped 2 psi.

 

Thank you
Im not a newbie to modifying, just to turbocharged vehicles.

At WOT my AFR is 11:1
