ok so i installed my aem uego wideband today on my vibrant downpipe... i used the stock rear o2 sensor bung... (catted but cored) my questions are...1.... the gauge is jumping from like 13.6 to 17.... did i install wrong or is it cause of a band tune??? question....2.... i only used the power and ground wire and dont know where to put the blue and white wires???? if someone could let me know whats goin on that would be awesome... im gonna be driven to nashvilla early sat morning to i need to do it after work tomorrow.... thanks alot for the help in advance.....

 

bump.....

 

The blue and white wires are the 0-5v output and ground for hooking them up to a tuner.

Not sure why the afr is jumping around though, never had that problem with mine.

 

Did you buy it new or used?

 

my recomendations:
1) put ur 02 sensor back in the factory bung and go get a bung welded in before the cat closer to the flex pipe, this will give you a lot better and more accurate readings, it should help your ratio from jumping

2)if option 1 doesnt work for the jumping ratio part then buy a new sensor lol

you still need to get a bung closer to the flex pipe!! its like 10-20 at ur local exhaust shop.....and you only need to instal the two wires the hook into the back of the gauge...being the power/ground wire and the sensor wire

 

yes, you need a bung welded in, at least a 10* higher and not in a straight line. taking out your rear o2 is not the way. The wideband gauge came with a little bung that needs to be welded in the dp, a shop near me I only paid $20, but make sure you get it before the cat, gutted or not.

the blue and white wires are for your tuner (you have no use for them)

afr is probably jumping around because you took the rear o2 out. 17 is extremely lean, when you get it all said and done your wideband should read 14.7-15.3 at idle, light throttle is around 13.8-14.8, and wide open throttle or wherever Zach06blowbalt put where you go into wide open throttle.

 

Ok.... thatnks....

 

Great timing on this one!!!!!!!!! I am saving to buy a wideband so I can get a tune. Was wondering about installation how 2s.

 

Its real easy... get a new o2 bung welded in put the wideband in there... and just run the wires... the hardest part is the power source... but its not that bad...

 

Nope, just a slight pain in the **** running the wire down,( I used a coat hanger) ADD A FUSE....easiest way for power.

 

I have found that bulding a fuse block is the easiest way to power multiply things in you car, but for a simple wideband an add a fuse will do.

 

or you can just run the power wire (red wire) to your injector fuse and wrap the WB power around one of the prongs of the injector fuse and plug in vwwalllaa!! easy and I've been running this power supply for a month now.

 

well drawn out!!

 

took me a whole 5 mins!

 

I had mine isntalled yesterday and it went in p[ost cat also. Thing is jumping around so much you cant even read it half of the time.

 

yupp thats ur problem too, go spend the $20 to have a bung wleded in before ur cat and it will work perfect....

 

or you can just tap into the sunroof fuse, why mess with something important.....

 

yea mine is tap'd into my windsheild wipers from the fuse box in the passenger side floor board....works just fine

 

it doesn't matter which fuse. just use a fuse that gets powered when car is turned on.
