Hi,
I have the intercooler spray on the version 8 sti, I can convert it to run automatic on boost pressure for a tad over £20 is it worth while doing?
I will retain the manual button to squirt as well.

Nope, it is not as simple as that, the JDM cars work off the inlet temps which works far better than off the boost, for instance in hot weather your boost will be lowered by the ecu to protect the engine, hence that idea is out of the window, and in cold weather, well....
The only sure way is to buy a JDM car with said auto ic spray if you want it to run properly.

if your a wiz at electronics may be done fairly cheaply, using the existing inlet temp gauge signal, some control logic and a voltfree relay, then wiring the Manual I/C switch it.
If possible, a data monitoring using the OBD 2 port, which can trigger a voltfree relay by inlet charge temp (Not sure if the latest PSi3 or an Apexi unit can do this) and run I/C manual switch in parrallel through it.

For what it cost it maybe worth it then. I have been looking at adding a temp sensor to the intercooler wired back a temp control module.
The only thing that I am thinking is I may need to wire round the timer relay other wise it wont spray again till it clears the dead band of the switch.

Just looking I know its best with the temperature probe in the air flow but do you think it will work with it just mounted on the intercooler? Surely this get just as hot.
I'm thinking log the inlet temps via obd and monitor temp of intercooler to find the difference between them. That way if there is an offset I can adjust the switch to suit.

Mine is "automatic" in that it uses the boost pressure sensor switch feature of my PSI3, through a DIY relay box with it's own switching if my water tank gets low- not including the PSI3 cost me about £8 in parts from Maplin.
