Electric diverter valve?

I see on the russian blogs some people are converting 1.8Ts to use the (electric) DV from 2.0T.


Makes sense, since the existing one is controlled electrically anyway, via vacuum. thoughts?

Welp I ordered the parts to try this... I'll post a diy for the wiring and whatnot when it shows up

It looks interesting. Curious to see how it works.

What's the point?

I'm guessing you can control the bypass in your tune. Not sure what that means in terms of performance though

Deletes the N249 and a couple vacuum lines, maybe faster response / better reliability? I'll need to try it and log, I can't find much information about the swap.

I think coming off boost it should work properly, as currently the system notices you letting off throttle, hits the N249 to apply vacuum reserve to the DV before the throttle slams shut. It would just be taking the vacuum out of the circuit - the N249 wires would be directly actuating the electric DV now.

What I'm not so sure about is other situations. Is there any time when the N249 is 'off' (so DV is effectively connected to intake manifold, not vacuum) and it is open? As this will only have N249 signal as an input, not vacuum, and that opening would be missed. (eg. low throttle % cruise, maybe.. so intake manifold vacuum is high.. if N249 is 'off', the pneumatic DV would still be open..?)
