NISSAN CAS disc options 24-1 24-2 24+1

Just ordered my emu black for my single cam Ka24e turbo build. Super excited. I have LS coils. Need a CAS disc for better signal. Running both cam and crank off dizzy as most single slammers do.
Does the software care what disc I get??

24-1 or 24-2 or 24+1??

There are a few made but looks like only the 24-2 APM EFI model is available for what I need. The 54mm disc. Thanks all!
