Wanting to disable my rear o2 sensors completely for troubleshooting. Pretty much just make the ECU not even look for them as if they where not there. Is that a possibility? I know you can simply dissable codes related to them, but Im not going for that. I basically want my rear o2's deleted as mentioned above. I have osiris tuner. Thanks!

 

Anyone? I read the Osiris user guide and only saw code disabling via ROM editor. I always here people talking about turning off the sensors, but that may be with another program...

 

Pretty sure it's doable, but I don't know the software well enough. My tuner was working on some of that the other day but like I said I'm not that familiar with it all yet.

Someone will likely chime in soon enough

 

Not sure about that. you might want to PM seymore as he's a licensed Osiris tuner. If he gives you an answer please post it back up here, I'm curious as well.

 

^ Sent him a PM. I'll let you know what he says if he replies. Trying to sort out why my AFR's keep richening up causing it to fight to hit targets and eventually throwing the dreaded p2a00 & p2a03.

 

Received a reply and it is possible and is done frequently... However, even though I have the full Osiris tuner w/ cable I cannot do it myself. It can only be preformed via a pro-tuner/cable.
