What do Port a, b, c and d log?

I'm wondering what these ports actually log? thanks,

They host a multitude of flags by setting bits in each. For example:

Code: Select all

   fanOn            = { porta & 0b00100000 } ; "Fan/W Inj Off"
   nosReq           = { porta & 0b00010000 } ; "NOS/W Inj Off"
   nosActive        = { portd & 0b00000010 } ; "NOS/Tables On",   

So you can see that if bit 6 (counting from 1) is set on port a, it indicates the fan is on, bit 2 on port d indicates that NOS is on. I just got these looking through the extra ini file.

Maybe someone has a comprehensive list.
