Hi I started to play around with the Boost lately and notice the Solenoid DC% does not follow the base table even though there are no corection active at that moment. In the log the Solenoid DC is reported as 33.4% when from the table it is 29.3% What could cause it? ![image](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/9/9b92b4d2590b66221dce67e15ca7ede13dfe3b1d.png) ---

Hi, look at the help description for _Control_: ![obraz](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/9/905bf53b2b81770698e86a73d4171f9103c0c1af.png) The base table does not define the duty cycle directly, but the percentage of the configured duty cycle range in _Min_ and _Max_. Let’s make the calculations of this case: control \* (DCmax - DCmin) + DCmin = (29.3 / 100) \* (90 - 10) + 10 = 33,44 ---

Understood! Thank you!
