a small gimmick: first system: because the cleaning I no longer need the headlight cleaning system. therefore I have the system used for a water cooling of the intercooler, and it's controlled depends the boost pressure. so the water consumption is kept within limits. second system: electrically switch between original pop off valve and the open hks pop off. regulatory strategy: the hks pop-off can be operated alone, or in combination with the water cooling of the intercooler. but in return, the water cooling not alone. the immobilizer diode still blinks as usual. of course, also at ignition off etc. here shown in pictures: system off / original pop off valve active: hks pop-off active, original pop off valve inactive & intercooler water cooling off: intercooler water cooling on / standby & hks pop-off active, original pop off valve inactive: intercooler water cooling active & hks pop-off active, original pop off valve inactive:
How did u manage to control the ic water pump using the original lever? I adapt some sprinklers to another water pump and original was thinking on puting a switch, but its a clever idea use the oem lever
thanks! the orignal lever, turn on only the system. the control takes place in the black control unit (selfmade, boost depending and adjustable when it should cooling) in the ebox in the engine compartment. so that the switch responsive to the pump lines, I had "only" to put on a few cables at the uch / ebox for the interior.
an electronic circuit, for which I use the boost pressure sensor signal, and 2 pot to switch on and off set. The LED shows you optical, when the waterpump will be run:
And is not more easy use a mechanic air switch, conected to the vacum pipe. Was thinking on this last night. Duno if there is something usable, something like a selenoid. Similar found a preassure switch but they work over 80 psi
Find these http://www.kronosvarese.com/tecnica/pressostati_principi_funzionamento.pdf MPL-503 sensor, think it might work as automatic switch
