That's exactly what I meant. The difference in what the ECU is expecting for each sensor.

Here's an air density vs. temperature chart that illustrates what Old Mechanic is saying above:


The difference in density between 70F and 160F is 15%. Can we assume that this difference will equate to a 15% difference in engine load, providing all other variables remain constant?
