One of the nicest features of the Giulia Q are the switchable exhaust valves. As soon as they are in the open position, the Ferrari V6 clears a throat that bleaches the late Mr. Pavarotti. In short SPECTACLE !. But unfortunately Alfa Romeo software engineers have not thought about when the valves should be open or closed.
It is logical that the valves must be permanently open in Race mode, but not everyone always wants to ride in Race to enjoy the sound. The enthusiastic switching behavior in Race is not always necessary and some backup of the traction control system is often desirable. That last is missing when driving in R mode. Traction control is present in the other positions of the DNA button, the most in A mode and the least in D mode. However, the valves will only open at higher engine loads and revolutions. This often happens at a time when you actually do not expect it, which causes you a certain amount of shock/unrest. Outside the car it also sounds strange when the valves open and close again a moment later. Not so tough ….
The ESC dongle puts an end to this inconvenience. In this case, ESC does not stand for Electronic Stability Control, but for Exhaust Sound Control. With the ESC dongle the outlet valves can be opened under all circumstances. So also in the A, N and D position. However, the original control strategy runs parallel. So either the dongle opens the exhaust valves or the car does it itself. The dongle cannot force the outlet valves to stay closed.
How does it work?
The ESC dongle is plugged into the EOBD plug next to the steering column under the dashboard. The green LED on the ESC dongle comes on and then needs about 4 seconds to start up.
The outlet valves are opened by pressing the button on the gearselector for about 2 seconds. On the clock panel, in the speedometer, the ESC light flashes for 3 seconds to indicate that the system is active. The red LED on the dongle comes on.
Closing the valves is done in the same way; press the button on the gearselector for 2 seconds. On the dashboard, ESC OFF lights up continuously for 3 seconds and the red LED goes out.
When the ESC dongle stays in the EOBD port, it remembers the last set position of the outlet valves.
The dongle is designed to be able to sit semi permanently. About 1 minute after the ignition is switched off, it goes into sleep mode to minimize power consumption to 24 mA. This allows the dongle to remain connected for several weeks without any problems.
What is the difference with the ESC v2?
- The ESC v2 is based on the hardware of the Performance Logger. This means that an ESC v2 can be upgraded to a Performance Logger in the future.
- In addition to the ESC/ESC off light in the tachometer, the ESC v2 also indicates via messages on the information line on the TFT screen between the speedometer and the tachometer whether the exhaust valves are open or closed.
- The ESC v2 is about 25 mm shorter, which means it sticks out less far below the dashboard
SGW firewall present?
When a SGW firewall is present, the dongle does not work. In that case our SGW bridge can be installed.
All Giulia’s and Stelvio’s are equipped with the SGW firewall from production month February 2018. Therefore, if in doubt, include the chassis number of the car in the E-mail so that we can find out whether an SGW is present.
