On the Sniper EFI, where is the best place to put the WBO2 sensor? I've looked through the Sniper EFI instructions and there is no mention about the WBO2 placement. I'm assuming it would be similar to FiTech's instructions. I would prefer to drill into the exhaust and not the header collector. My plans are to use the passenger side about 2" behind where the header & exhaust bolt up, but on the exhaust side, and at about a 10° angle.
WBO2 sensor placement?

Danny, I put my WBO2 sensor about 2 inches before the bolt flange, instead of after (sensor is on the header). I erroneously thought the "collector" was the point on the header where the pipes came together, not the bolt flange. This would be about 4-5 inches forward of caverman's suggestion. Should I move it?

I'd have to see a picture of your header (merge) collector/WBO2 sensor location. I consider THIS a bad location.May God's grace bless you in the Lord Jesus Christ.

Yeah, the WBO2 sensor probe is right in front of one primary tube. It would be better located after the collector flange.

FYI: When viewing A/F Ratio, it did seem to bounce about +/- 0.25 from target.May God's grace bless you in the Lord Jesus Christ.
