Hello everyone,

I am currently working on a Renault F4R engine with VVT (from Clio RS / Mégane RS) using an EMU Black.  
I would like to ask if someone has already configured the crank (PMH) and camshaft (VVT) sensors on this engine.

Here is what I know / have tried so far:

- **Crank sensor (PMH):** VR sensor, 60-2 toothed wheel, rising edge, works fine.

- **Camshaft sensor (VVT):** Hall sensor powered by 12 V, 4-tooth asymmetrical wheel.

- The cam signal seems to be similar to a “VW R32 4 teeth” pattern, but I am not sure if this is the correct trigger type to use in EMU Black.

- I am wondering if I should configure it as “1 tooth”, “VW R32 4 teeth”, or another option, in order to get proper VVT control.

- Also, should I use the **CAM sync tooth window** for extra stability with VVT?

Has anyone already done this setup on a Renault F4R VVT with EMU Black?  
Any advice, example configuration, or Triggerscope screenshots would be really appreciated!

Thanks in advance 🙏

If not resolved already, N+1 is the correct setting for the cam pickup. I have done this on multiple F4R’s with VVT working.
