Wideband placement with a divorced wastegate
I'm finishing up my nissan rb25det build and have a question about wideband placement. I'm running an aftermarket turbo and manifold with an external wastegate. The wastegate is set up to dump to atmosphere. The main exhaust is routed through the exhaust system as normal. The wideband is on the downpipe, in the main exhaust flow. I'm worried that having the exhaust from the wastegate bypass the wideband is going to skew my readings. At the same time, assuming its a homogenous mixture, even if some goes a different route it should still be the same reading. Is this going to be a problem? I may still be able to tie the wastegate into the downpipe before the wideband if it'll be an issue.

I don't know for sure if this is a problem but can't imagine that it could be problematic. I've seen several builds with your proposed scheme and the WB was working as expected, no unexpected drama...

Mike is correct. It'll work fine.
