The chart for the CTS has now been 'constricted' to a shorter ranges of values but it has the SAME shape as the original. At the hot end of things it impossible to tell the difference from the original 'curve' vs the modified curve. I charted both. It's at that end where the 'goodies' happen.

Note that this is A/C's sensor not the ECT. So we're not fooling anything associated with the engine power train management.

At cold, 20 deg C, my normal CTS looked like 4.7K; with the mod it looks like 960 ohms. This is well outside any normal function for the A/C. Even if it thinks it a little warmer than it is, so what? No harm, no foul!
