Ecu Wiring Nightmare

[thricestrat]

Ok so when I bought my TSI the previous owner was a hack job. I am getting ready to buy / install my wideband. After checking out my new eprom, I realized that the front 02 wires have been spliced and also feeding the rear. Ive heard about doing this with an NA motor but never a boosted engine. My biggest worry is that if I leave the wiring as it is, I wont get a correct reading. I am currently running a cat delete DP if that matters. Also whats a decent wideband to buy? I want one more for monitoring purposes, and tune via safc II and my maft. Im completely new at tuning any suggestions would be HIGHLY APPRECIATED!

Well I run the AEM Wideband and it seems like a good setup. Not sure if have the O2's together would screw it up enough to make a difference, but I'd undo it. There is a mod were you can jumper the O2 out. With dsmlink you just tell the sensor to hush up .

Thats what I figured. Im probably going to just undo it rather that deal with a headache down the road (potentially). Where did you get your AEM ive been searching around and cant find one.

thanks
