Here's a thought: If you are relocating the O2 sensor to downstream of the
header flange, you may want to find and twiddle with the code which
determines how long the engine runs before going off of its start-up code
and tables, onto closed loop--don't leave it trying to go closed loop
before the sensor is hot enough to work properly.--The relocated sensor
will get hot enough, but it WILL take a bit longer to do it!
