After reviewing the calibration (using HP Tuners) the TIP Sensor and MAP sensor have identical calibration values. However, while logging data it is apparent that the two sensors are in fact no the same....

While the TIP Actual is reporting 77 inHg, the MAP sensor maxes out at 75.3 inHg while the throttle angle is at 100%..... I've performed multiple runs and the MAP consistently Maxes out at 75.3 inHg...

If the two sensors are in fact identical, then there must be a max value limit in the tune......

Or is the MAP sensor a 2.5 Bar sensor???

Take a deep read from our in-house guru :)

Thanks for that reference..

I was already familiar with the EcoBoost Load control strategy.

My question was in regard to an apparent mechanical range limit of the MAP Sensor....

The calibration has the same slope and offset for the TIP and MAP Sensors (Slope: 19.455, Offset: -1.876). This would support a maximum value of 95.39 inHg.

With the Throttle position at 100%, the TIP sensor reads well into the 80-85 inHg range while the MAP Sensor reads a maximum value of 75.3 inHg.

It seems apparent that the MAP sensor has an upper range limit of 75.3 inHg. Seeing that the sensor calibration data supports values up to 95 inHg, my thought is that there is a MAX MAP Value Limit or that the calibration data is for a different sensor.

In either case, something dosent seem right....
