I'm running an Alcatek on my (UK) widetrack blob and noted that it supports automatic water spray control, but according to Duncan it's only valid for JDM cars fitted with auto water spray, so my question is - how easy is it to retrofit that and what bits would I need?

Anyone done it?
The car's on a FMIC anyway (relocated the nozzle to the bumper to spray the core in the centre) so probably won't add much performance anyway given the size of the front mount's core vs the standard top mount, but I'm curious to see how easy it would be and if there are better spray mist jets that will do a wider arc where I could buy them from.

I'm guessing I'd need the Auto toggle button here plus a wire from there into the ECU and another to trigger the manual button's circuit, as the ECU will be responsible for calculating when the spray would need to be triggered.

Is it that simple?
I'm not interested in wiring up loads of relays or sensors; in theory I'm guessing it shouldn't need any of that anyway as the Alcatek can read it all, so it should really just be a case of how to connect the Alcatek to the intercooler circuit.

Yes it can and has been done and you don't need an auto switch fitting to the car.
Let me have your email address and I'll email you the instructions.
