I really need to filter a pressure signal from an analog input. I’m struggling with a noisy fuel rail signal causing issues with a PID I’ve setup to control the pump, filtering would help greatly. ![Screenshot 2025-09-11 072235](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/6/62fa83cba59fe6fc96a4552a361405d452c54654.png) ---

Hi, We will add a native way to filter the signals in future updates. For now, you can make a simple IIR filter in the project tree. Filter strength is from 0 to 100. ![obraz](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/9/945154e136afd03a208833a72c9859edab1d0e62.png) ![obraz](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/6/699f5ec877c3ec5891830c1bf8098f088745c883.png) ---

Many thanks, I’ll give it a try
