I had in mind some sort of electronics wizardry to get the air from the hottest part of the exhaust manifold and keep it at a fixed temperature no matter the airflow. ( but i sold that car, and now have a turbo car, so i am not sure if this is such a good idea).

What i should have asked is, should the input temperature be dependent on rpm and load. Or is a fixed X F or C best or is there a more complex algorithm.
