today i've tried to control the actuator with the Arduino but it didn't work, I should remove it from the car and do tests at home but it's a bit complicated and testing the signal from the car is complicated too as you have to start and stop it everytime, also I don't want to burn something inside car's ECU. So i've decided to do something easier, as the valve opens when the car starts and it stays open for like 10secs I'm thinking of making a sort of remote disconnection of the valve by putting a relay on the +12v wire on the valve and controlling it with a 433mhz RF remote to disconnect it by opening the relay so the valve won't get the power supply and will stay open. Do you think it should work?
