So my new hot side is done and now I need to place my O2 and wideband.

Its a single turbo with crossover. The plan was to run the O2 for the stock computer in the downpipe with the wideband. Rears have obviously been deleted.

I was talking about this with someone the other day when I mentioned going with HPT over the Holley they went with. They mentioned that the O2 needed to be pre-turbo but wideband in the downpipe was OK. I said unless its in the merge it won't get an All 8 reading, and I didn't think it would take the heat anyway. He said put one O2 after each manifold.

So what's the deal? I was going to put a single O2 in the downpipe about 12 inches from the turbo and the wideband 6 inches or so after it. Is this the wrong way to go about it with the stock computer and HPT.

The stock computer looks for O2 inputs from both banks.
I put them just after the v-band on each manifold. The wide band is in the down pipe, about 12" after the turbo.

Mine is also set up that way.

Yeah I just wanted to double check on this. I've used a lot of different aftermarket ECU setups that'll run on a single O2. This is my first time with HPT and I'm just not learning some of the interface.
