Hi everyone, I am experiencing an issue with the Short Term Trim correction on my Ecumaster EMU pro. Even though all the configured activation criteria (RPM, load rpm RATE…) are fully met, the Lambda status remains stuck in **“Recovery Delay”** for exactly **600ms** before transitioning to active. The issue is that my **Recovery Delay** parameter in the software is explicitly set to **100ms**. Many thanks!!! ![image](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/7/7634088cc3c972b85a80d0fc4a8ee39c0fe57d8d.png) ---
