ESE - 2.7L And 3.5L GTDI With Satellite Radio Only

ESE is an audio system feature that enhances certain engine tones typically induced under wide open throttle or heavy part-throttle conditions. The system uses a DACMC (contained within the ACM) and the audio system speakers.

The DACMC determines the engine tone to enhance based upon engine rotation speed data, engine torque data, and accelerator pedal position data from the PCM. The data from the PCM is processed and converted into an analog audio signal, transmitted to the DACMC internal tone generator, and output by the ACM to the LHF and RHF door midwoofer speakers as fluctuating AC voltage.

:roflmao:

VW is spending a whole lot of engineering time and effort figuring out how to pollute the world.
While it sounds like Ford is spending a lot of engineering time making the engine sound better.

:high5:
making fake engine sounds through digital processing.

DACMC

The DACMC ESE functions only operate while the engine is running and all doors are closed.

The DACMC is a digital signal processor that consists of an internal analog/digital converter and tone generator.

The DACMC uses engine rotation speed data, engine torque data, and accelerator pedal position data from the PCM to calculate the targeted frequency needed to enhance engine noise within the passenger compartment. The DACMC ESE frequency signal is output by the ACM to the LHF and RHF door midwoofer speakers as fluctuating AC voltage.

When the engine is running and the audio system is in use, the ACM fluctuating AC voltage output signals to the LHF and RHF door midwoofer speakers as fluctuating AC voltage contain a mixture of the ESE frequency with the audio signals.
