O2 sensor question

Everett Vassar · 07-25-2017, 12:24 AM

Installing a single o2 sensor/logger in the header collector. Does it matter which one? Does it need to go right behind where the tubes go into the collector? Or further back?

Good info in this old thread... http://www.classracer.com/classforum...dvanced+timing

Sensors installed in a open collector will give bogus lean readings at idle/slow speeds...just a heads-up.

Had the same questions. I called the tech line at AEM were I purchased the AF unit from. Those guys answered all my questions about placement and why the readings were what they were in regards to placement, of the sensor, in the collector. Very knowledgeable and helpful.
