so i took out my front 02 sensor and put my widebang sensor in its place i wired it into number 76 pin and the wideband reads but my dsmlink throws the check engine due to 02 sensor but besides the fact wen im 30 percent throttle it reads in the 14s but as soon as any more then 30 percent the a/f drops to 10 and it barely pulls and bogs? do i need the stock 02 sensor?
 
You can run on just a wideband with dsmlink. You need to have the input set properly to the kind of wideband you are using and have it set for narrowband from what I remember. Sounds like something in dsmlink is not configured properly.
 
Narrowband simulator from what I understand is an option in dsmlink. Need to have it checked.

This is normal, just uncheck o2 on the DTCs tab

wen im 30 percent throttle it reads in the 14s but as soon as any more then 30 percent the a/f drops to 10

This is because the ECU is switching to openloop and/or the fuel table is set to do this. Completely normal, unless your fuel table is a mess...

it barely pulls and bogs? do i need the stock 02 sensor?

Did you try simulating narrowband? Why don't you post a log so we can see what's going on...
 
link v3 is the only version that will let you run a narrowband simulation. that's what you need to setup then input into link what kind of wideband your running.
 
I have a aem wb02 and I have v3 I put all the settings back to stock I put my 450s back in LOL ill try switching the settings and ill let yous know and ill try an post a log wen I get out of work thanks guys
