Default 95 turbo, DIYPNP, bak bak on cold start.
Msq attached and a link to the bak bak video on cold start - on warm start no bak bak.

I'm running the same msq, fuel and spark are a bit different.

Let me know what you think
Elior

Thanks

Can you push the space bar while logging when anything like a backfire happens?

This may just be a case of the WUE needing a little fine tuning.

All the way to warm engine (>65C) the engine shakes badly.
