I have an AEM Uego and have had it's readings verified on 2 different shop widebands. I can't speak for the thousands of Uegos out there, but mine, for one, is accurate.

I also have prosport gauges with the warning functions. I have boost, egt, water temp, and oil pressure. The oil pressure one is a little annoying because it's warning is low. The way mine is wired, if I turn my car to "on" but not start it, the gauge starts reading. It reads 0 oil pressure and beeps. It's a little annoying when I have to have the car set to on to read the int-x but it's livable. My boost gauge consistently reads almost 2 psi low. It isn't really a big deal as I don't check the boost gauge much. I just noted it when I set the warning and set it a little low. The reading is consistent and that's good enough. Prosport would have warranteed the sender unit, but I had already had it for a year. The red gauges match the factory interior fairly well. When setting up my idle, it would bounce (common issue with int-x). I didn't really care, but I could hear the beep of the idle falling and the oil pressure dropping with it. It actually inspired me to get the car to idle a little better as to maintain oil pressure. EGT can tell you a lot of things over time. Mine is in the downpipe though and only really measures long term trends.

^thanks for the input. Hopefully my AEM UEGO is accurate as well, I'll make sure when I get it tuned on saturday. I'm gonna end up going to Maximum Autosound in NJ. If I remember correctly, you were the one who told me about them.

Yeah - tell Rob I said hello. I might stop by. I need Rob to order me some parts and I'd like to see what's going on with their shop 8. I haven't been by there in a while.

The only chance that AEM UEGO wideband will be accurate is if it's way downstream in the exhaust and not directly behind the turbo. Those AEM widebands use the Bosch sensors and those sensors are garbage. I cannot stress that enough. If you guys are wanting a good wideband, get yourself an NGK Powerdex or AFX and make sure you get the one that uses the NTK sensor.

Ah, well then I should be golden. My turbo is front mounted, and my sensor is in the last bung on my TurboXS exhaust, back in the pipe between the cat delete and the tail pipes. It' basically at the limits of the cable length, can't get any farther downstream.

Will do when I go, but I probably will go next week not this week, I gotta fix a problem with my coils.

I have my wideband installed after the downpipe just before the shell of the cat.

I read on the AEM instructions that you should install the sensor down stream a minimum of 36" as it can't handle the heat (anything over 800degC ) closer to the turbo . So I'm thinking i'll put it in the hole in my gutted cat .

my UEGO was installed on the catless midpipe (where the cat would have been). It worked flawlessly for 2 years there.

The Bosche sensor that some of those widebands like the AEM use can't handle heat, will begin to become inaccurate with alot of heat, react more slowly, and they also do not last very long. Cheap, cheap sensor. Toss it in the trash and use a controller that can utilize an NTK sensor.

Ok ok we know where you stand on the AEM w/ Bosche sensor situation! :lol2:

:rollingla

Fine, then. Don't listen to me. Learn it the hard way. ;)

i am using the cobalt, it's little bit expensive, but i think it's one of the best, and it's also blue. haaha
