Re: BMW N55 electronic wastegate
Thanks for the quick update. This is good, all makes sense. It appears the rod is at 1.2V at idle.
I think the next steps are leaving the sensor unplugged, go for a drive...
1. Slowly squeezing the throttle, if there are no boost, you can continue to squeeze the throttle slowly until wot.
2. Again squeezing the throttle slowly, if it starts to build boost. abandon the test.
This test is to confirm at what rod position in relation to boost or no boost. Once we have established this, we can then manipulate the pin #4 signal and control boost.
Do you think this is a good plan?
