OK so i have such issue with mostly all bmws when i wire Vanos solenoid to ECU does not matter is it single vanos, double vanos M54 or S54 there is same issue to not make things complicated lets talk about M52 vanos solenoid that has just switched +12v through relay and ground control when i use OEM wiring and leave +12v feed from injector relay, i can not turn ignition off when solenoid is connected to ecu, it back feeds everything if i start engine, turn ignition off, engine is still running and meanwhile if i disconnect vanos solenoid it will shut everything off (as it should when ignition is off) i'm talking about E36, E34, E46, E39 cars it is not car / chassis specific it is wiring related. i wired relay for vanos solenoid separately which does feed solenoid separately and relay activated by injector power relay. but still does same thing it leaves ignition ON (but not always) i put diode on power wire between vanos and relay.. worked for day and then it did same thing and now it does always - leave ignition on how do u guys solve this issue? used exactly those methods of wiring as well - no luck

Hi, I've just fitted my new ecu (Fury) to work with my e46 s54, so far I've got it running and idling (just using base parameters) but I need to set up the vanos. Has anyone got any info they're willing to share for getting the vanos mapped in correctly? Eg. a vanos map or base settings that can get me going Thanks in advance
