You need a SD2/3 and a laptop with dealer software combined in order to re-flash the dash ECU with the new settings.Further to this discussion on the Launch X431 system - has anyone used it to adjust the suspension? I notice on the KW suspension site they mention using the SD2 to turn the Skyhook system off when fitting KW3 coil overs:
see installation manual part...
Of course this does beg the question whether in the interim you could simply switch the Skyhook off and retain the faster gearshifts and exhaust noise?? Anyone done this with the Launch or SD2/3??
Without the laptop the SD2/3 can only access those settings as "read-only" so you will not be able to change anything
If the Launch can even access those menus I highly doubt it can change the settings
Also it is not a matter of changing one setting and switching off SPORTS mode... As I suggested above the entire ECU firmware needs to be reconfigured from blank factory settings
