Close to installing my SPFI on my EA81. Waiting on a few things in the mail including a new O2 sensor from the states.
Would like to brainstorm you guys and my local Subie forum Ausubaru for the best location for the sensor. This is a trike and in Oz trike arent subjected to anti pollution requirements. So the custom twin exhaust has not cat.
There is a connecting pipe between both exhausts. This pipe is only 7" (180mm) from the exhaust manifold. I'm assuming it best be placed about 4" from the exhaust manifold meaning 2" from the connecting pipe? On a 45 degree angle. What are your thoughts?
