OEM ABS software was not written for what track rats and autocross guys are doing. Ice mode has been around for twenty years and will probably be around for some time to come.
The old solution used to be (and still is) to swap out the OEM ABS for another, better system - which itself is an OEM system, either from the same or another manufacturer. Racers with money go Bosch Motorsport.
How those would integrate into the twins' systems, I have no idea, but based upon this text from the GT86-specific MoTeC M1 stand-alone ECU datasheet, I suspect it's a bit of a job:
ABS / VSC
• While this product uses some sensor information provided by
these systems (for example Wheel Speeds) no further interaction
occurs.
• Any operation of these systems that does not require engine ECU
interaction (for example VSC Disable Switch) will function normally.
I don't know how VSC is controlled but I'd guess that ABS is controlled via a stand-alone ABS controller/ECU.
