I know the JDM 06 imprezas have auto water spray facilities (amongst others) - is there any way to get this amended in my rom to allow me to fit a switch to the IC sprayer and have the system auto spray for me?
At present I have a manual IC sprayer button.

I'm not 100% positive, but I don't think that the 32-bit ECU is involved is controlling the IC spray as is some of the 16-bit ECUs. I'm guessing a separate module is involved.

hmm. I am sure I saw a 06 JDM STi hex with the IC tables in there, I will investigate further as it would be nice if this could be added to the std UK rom.

IC tables where? There are no IC tables defined in the RomRaider definitions other than for select 16-bit roms.

Yep - definitely in A4TJ121B JDM 05 STi but I believe that is 16bit

Yes, that would be one of the select 16-bit roms. 'Intercooler auto-wash relay' is one of the potentially supported SSM switches that could be monitored (and is so on those select 16-bit ECUs). None of the 32-bit roms of vehicles that have IC spray that I've checked support logging of that switch. So, my assumption is that it is not handled by the 32-bit ECU.

There's a how to post over on Nasioc for a boost controlled IC spray using the above mentioned switch. Should do just what you're looking for.
