Hey guys i just ordered a AEM wideband kit the other night. Im not to sure how to hook it up so if any one has any helpfull tips on how to install it would be great. Also what is a good air/fuel ratio i should tune for? My mods are all up todate please look at them.

Thanks.

11.5 : 1 Under full boost.

As the turbo spools i see high 12's, but once im 1bar+ its 11.5:1. Hooking it up is easy, power and ground and install the 02 into the exhaust.

Thanks man when i ordered my stage 3 keydiver chip jeff set my chip to a 10.5:1 does this seem about right?

Also when installing it is there any wires i need to tap into the ecu?

This is false information, unless you're running meth or race gas. For a novice tuner, I would NOT go over 10.8:1 until you full understand a/f and the theory behind it. It doesn't take much to understand either, i'm not insulting you, just being sure.

The UEGO has 2 harnesses. 1 for the sensor (4 pin, no wiring) . and you just use the power and ground for the UEGO, unless you want to wire the third for logging with dsmlink/EMS.

wasn't that you i was PM'ing back and forth about what wettings on the back do what because you were wanting to log it? Maybe i'm thinking of the wrong person???

Leave it set stock if you acna log 0-5 volt... P4 is 0-1 volt and P2 is 1-2 volt with the output actualy showing an AFR if you move the decimal over one spot to th eright when looking at the numbers

Ive heard some people say to use p4, and some people say to use p3?

Mines is on p4 at the momment, I hope that its the wrong setting and that im getting a off afr reading
because my car has been knocking lately if I do a pull, and the funny thing is its the same timing and boost its always been, I just adjusted the AFR with the gm maf-T to whatever looked ideal on the WBO2 and the wide band is showing me 11:1- 11:3 during WOT... 2 weeks ago my knock sensor kept blipping a bunch of knock randomly and disappearing as fast as it came. It was triggering my knock buzzer at any given time, and I was getting a CEL going on and off for the knock sensor. I wiggled some wires around back there and unplugged the KS and plugged it back in and it went away, but maybe my current knock is relevant to what happened 2 weeks ago and not the WBO2 settings?

Sorry to thread jack.
