2015 Coyote F150 Map settings

[speed 365]

Tuning a 2015 F150 coyote, boosted, there is no slope setting in the tune, looking at other tunes here, some have and some don't. Can anyone shed some light on this for me please? Thanks in advance.

Sure post your tune and your stock read

Just for clarity you are referring to the Baro, MAP, TIP, and SIP sensor slope and not the speed density slope correct?

NA applications will have a MAP senor. Turbo charged applications will have a TIP sensor and MAP sensor. Supercharger applications will be SIP sensor and MAP sensor.

NA and SC applications don't need a barometric sensor, they can calculate it. Calculated Barometric pressure comes from the throttle body data and estimated airflow between BARO and MAP pressure difference for NA. Then BARO and SIP for superchargers. Turbocharged application can't use TB data and airflow to calculate BARO as the two pressures on each side of the Throttle are TIP and MAP, so a barometric sensor is required for anything that uses it.

If you are missing the slope for the MAP sensor, it may just be misrepresented as another of the sensors in HPT's editor, contact support with the ECM number for MAP sensor slope you see in other calibrations and your stock calibration and make sure they have it represented accurately.
