You seem to have slightly missed the point with regards to how temperature calibration tables within an ECU work.
You map at one temperature, then you setup tables to tell the ecu how to vary the fuelling and timing at other temperatures, this setup is based on where you have the temp sender and how the values it gives are calibrated relative to the actual mean average temp of the charge entering the ports in the head.
You also have tables to approximate the amount of heat soak you get into that charge from the ally of the head and inlet based on water temperature of the engine at the time, as this also effects the final intake temp of the charge itself.
No i havent, Your have missed my point,
Edited to say,
on awaiting in the fire up lane to run, My ACT's raise to 60+oC when at the plenum, but were less than 30oc at the boost pipe.
@ the end of each run @ the 1/4 mile point, my plenum temp had gone down to 50oC, but the actual ACT was still only about 30oC.
And due to this mod, i managed the same terminal speeds @ 4 psi less boost.
