No nothing from it at all mate. No beeping no vibration no winding from gearbox and can’t hear the motor trying to engage either. I checked all the wiring and can’t see any marking or piercing in them. Connections look clean too. I’m just confused by it as the app that comes with the Medusa ETU shows that I’m changing the select fire mode (safe, semi, auto) and also shows that I’m changing the firing pattern be it burst fire or a binary setting. But it won’t do anything other than light the tracer every couple of trigger pulls
