Hey guys, just wondering if anyone knows what is required for the 'Auto' button intercooler water spray to trigger? A few Subaru forums point to the ECU controlling this (unconfirmed). Does anyone have more info on how this works and under what circumstances (e.g. from x PSI boot & y intake temperature etc.)?
Specifically after info on how this works on the GCs, as it may be different on the GDs and newer.
Cheers.
