What you guys experience is absolute nothing new...even the Porsche 997 street cars experienced this in Conti series...as well as mustangs...camaros and even the BMWs so it isn't just a Nissan thing.
Almost all the cars is ST run the Tevus system (allowed to or not) and
every car in GS is now allowed a Bosch Motorsports or Tevis abs system.
When ran the ST 128 BMW after 2 events on the OEM stock pump ...it was toast and only got worse.
Basically I think ice mode burns up the pump and once you start having "ice mode" it will just keep getting worse or more often.
The man to talk to is Kurt Jung..is an electronic guru espc. on ABS systems.
He is also the main dealer Motorsports for the Tevus system.
The Bosch system is pretty advanced 10 preprogrammed maps and 2 specific maps based on inputs for specific car measurements....front and rear track, vehicle weight, wheelbase, and front and rear tire circ.
Both systems are expensive ...but so is crash damage.
