Hello again! I remembered, low voltage is lean, high voltage is rich, so simply adding a resistance to the output of the "spaced out" O2 sensor would allow you to enrich the mixture if desired. If what is stated above is correct, moving the sensor out of the exhaust stream will increase the sensor output voltage causing the ECM to lean the mixture in attempt to bring the voltage down. Adding a restance in line would bring the voltage down and the ECM wouldn't lean the mixture as much or at all depending on the amount of resistance. Maybe one of the double Es out there can work up a simple pot plus resistor circuit for us. I believe this is correct because till now fancy circuits were created to add to the O2 output to make the voltage higher so the ECM would lean the mixture. Then we need an inexpensive EGT setup. - Scott
