David Pereira Posted December 5, 2019 Report Posted December 5, 2019 Hi, I have a E36 M3 single vanos s50b30 I am thinking install the e36 plug in ecu It is possible make some changes in wiring to control vanos? has anyone done this before? Quote
Brad Burnett Posted December 5, 2019 Report Posted December 5, 2019 Pretty much anything is possible. Yes the vanos is controllable. Quote
Adamw Posted December 5, 2019 Report Posted December 5, 2019 If your is the USA S50 version then it should have the Bosch M3.3.1 which the Link plug-in is designed to replace. The Euro S50 uses a Seimens ECU with a completely different pinout. So start by confirming what your original ECU is. Quote
David Pereira Posted December 5, 2019 Author Report Posted December 5, 2019 This is a bosch ecu i think that only S50b32 is siemens So if i re-wiring the vanos sensor to a empty DI and the two solenoid to a empty aux outputs, it´s enough? because the car have a module only to control vanos "VNC" and i think that it comunicate with ECU via CAN. My idea it´s eliminate the VNC and re-wiring to the link plug-in ECU and calibrate vtc control. It is possible Other doubt, I have vanos only at intake cam but the system uses two solenoids, how can i calibrate which is which Sorry about my english Thank you for the help Quote
Adamw Posted December 6, 2019 Report Posted December 6, 2019 Use Aux 3 & 4 for the vanos solenoids as per below. Set both to Inlet L/H, 50Hz. The cam position sensor can go to DI 1-4. Also, I think the factory connectors on the vanos solenoids have diodes in them and they need to be removed, usually just chop off the connectors and use something common like a deustch DTM or similar.
