Reset learned values?
 
After replacing my actuator position sensor, tcv, coolant temp sensor and oil pressure sensor I want to reset the values as I'm still getting ECM-P003A17 code when I reset and drive for a small period. I cannot see anything in Vida to reset.

I also have ECM-U032200 and CEM-U030100

It wasn't on the car before I got it mapped.... I take it that it's nothing bad just saying there has been a software change?

It's an error saying that the software has been tampered with. The CCM and ECU compare signatures of the ECU software and if they don't match, the fault is logged.

It's one of the easy ways insurers/investigators can log whether a car has had the software modified from factory. As well as for warranty etc.
