At the moment I left the idle speed work from ECU, but I wanted to connect everything to invent for more control. About the connection error, I cut the cable which is number 3, I checked it with a multimeter and if I do not connect it back to the ECU again the revs are 1300, so the cable is definitely responsible for the idle. I'm wondering why the voltage on the idle cable does not change from "invent" even when I select manual idle in the settings and change the settings to 50 or 100 percent.
Of course I can leave it like that and drive, but please understand and help me, because it just annoys me when something is not done right. 😉
