BMW N55 electronic wastegate

[Richard L]

I can think of two ways to controlling the rod length.

1. Positive biasing the rod position voltage at pin #4. to the control loop should extend the rod and lower boost.
2. Positive biasing the T-MAP sensor.
3. Combination of the above.

I will set out a method to make this happen. I notice BMS sell a male/female plug for this wastegate sensor. If you can purchase one of those, I will pay you back. This will make life a lot easier.

Ok cool I have that harness already. I was actually going to mention it but I forgot. This harness only loops the wastegate rod position through the jb4....

Quick question, can this be done with a hfs-4 v2 controller? That's the controller I have...
