need to toss my o2 into the HF mani spot for the time being, any issues with this at all since its pre-turbo? i can disable it completely, tho the car runs like total *** in open loop, guess that means its just time to tune right?

The innovate website says an O2 will not work properly before a turbo due to excessive pressure. Wether it will work or not, I'm sure it will work for emissions.

I have my NBO2 in the HF spot and a WBO2 bung on the downpipe before the cat. Both work fine.

02 sensor in the stock hf mani. worked fine on my buddys car with the afc hack....

I ran the stock o2 sensor in my hf manifold for a while. When i tried putting my wideband in the same spot though I had all kinds of random lean spikes in the data that weren't there after I put the wideband in the downpipe. I think you should be fine running the stock o2 there though. Personally though I just tuned my part throttle and run my car in open loop all the time now.

yeah it'll be fine! i've ran mine that way for awhile. stock o2 in the hf manifold and when the wideband goes in it will be right after the turbo on the downpipe. i think with all wideband o2 sensors it is better to put it after the turbo on the dp for better readings
