A: rusEFI does not write to internal flash memory while your engine is running. In order to really write the values into the permanent memory you would need to stop the engine (or disconnect your stimulator). Online tuning is not affected by this issue - you can still tune and the new values would be applied right away, they just would not be saved until you stop the engine.
A: For most of the pinout changes to be applied you need to reset rusEFI. Do not forget to stop the engine so that the new config is saved into internal memory!
