Elite Rampa downhill issue

When going downhill I have to stop pedaling. My wattage drops to zero yet I keep picking up speed. I’ve search around and tried different P values, finding some that work to match my real world riding, but the downhill issue is annoying when I fly by people at 50mph. :grin:
Any ideas? …well besides by a new trainer.

Depending on your weight you should be picking up speed going downhill.

The P value should have no effect while going downhill at 0W.

Sure. I understand that but if I’m with other riders I begin picking up speed without pedaling at all and passing them up. I can see they’re wattage compared to mine at zero when I’m the only one going super fast downhill. The Rampa and Zwift have been a challenge since I bought it.
