Global default engine configuration This method sets the global engine configuration defaults. These default values are then overridden by engine-specific defaults and the settings are saved in flash memory.

This method is invoked only when new configuration is needed:

• recently re-flashed chip
• flash version of configuration failed CRC check or appears to be older then FLASH_DATA_VERSION
• 'rewriteconfig' command
• 'set engine_type X' command

This method should only change the state of the configuration data structure but should NOT change the state of anything else.

This method should NOT be setting any default pinout

Idle control defaults

between variation between different sensor and weather and fabrication tolerance five percent looks like a safer default

hasRememberedConfiguration

bool hasRememberedConfiguration = false

Current engine configuration. On firmware start we assign empty configuration, then we copy actual configuration after reading settings from flash. This is useful to compare old/current (activeConfiguration) and new/future (engineConfiguration) configurations in order to apply new settings.

todo: place this field next to 'engineConfiguration'? todo: not great that it's a global variable which we have to clean, move to 'engine' somewhere?
