MY17 New VDC “TRACK” – US Subaru Technicians help
 

As described here, a new management of traction and stability is performed in MY17. Minor changes are related only to switch on central console but the relevants are in VDC/VSC management.
When accessing in TIS (Techstream with J2534 read/write capable cable Mongoose official i.g.,or SSMIII) you can identify engine FW release and VDC FW release. Therefore you can upload new engine ecu fw and VSC too.
The questions:
#1. Is it downloadable (upon payment I suppose) the MY17 VDC/VSC FW?
#2. If positive, a prior MY17 board (car) can be upgraded?

Has anyone confirmed if pedal dance works on the MY17s?

Don't need to do it on MY17 -

Holding the "Traction-off" button (leftmost button, looks like a car with skidmark and the word "off" at bottom) for 3 seconds while he vehicle is stopped get you into an ALL-OFF (aka. You're on your own) mode -- This is what Toyota/Subaru intended for completely turning off TC and VSC. Brake LSD will be off as well if it's a MT but in an automatic transmission the Brake LSD will be in "TRACK mode" still. In the first gen FRS/BRZ with MT, Brake LSD remained on in this mode and often cause interference when the driver wants to take full control. This is perhaps why there was a need for the pedal dance
Indicator light so you know you're in this mode: "TRAC OFF" and "Car with skidmark with word OFF at bottom"
To turn off this mode, simply press the "Tracktion-off" button. This mode will also be turned off when:
- regular key-start vehicle -- engine switch is turned to "LOCK" position
- push-button-start vehicle -- push button ignition turned off
- note this mode will NOT turn off even after reaching 50km/h (~31 mph)
