Current global default tune available at https://github.com/rusefi/rusefi/blob/master/simulator/generated/simulator_tune.msq

Current vehicle defaults for a few selected vehicles are available at https://github.com/rusefi/rusefi/tree/master/simulator/generated/canned-tunes

Problem: reference custom tunes have a birthday somewhere in the past. We keep adding features with defaults for those features, we keep improving global default. While useful custom values go into canned vehicle defaults, at the same time reference tune should take reasonable defaults from current defaults.

For example primingDelay = 0.5 global default was added, https://github.com/rusefi/rusefi/blob/master/simulator/generated/canned-tunes/COUPE-BK1-comparing-against-current-COUPE-BK1-default.md reports override but really it's just COUPE-BK1 reference tune was created before that default. It's recommended to manually pick reasonable new global defaults.

See [CannedTunes] tag in all below mentioned files.

simulator\Makefile makes sure simulator has all needed compilation guards.

rusEfiFunctionalTest.cpp exports tunes into simulator/generated folder as .bin files - key point here is invoking firmware global default and engine-specific defaults logic in order to create a dump of that.

WriteSimulatorConfiguration.java exports tunes as .msq and github action persists those.

TuneCanToolRunner.java compares current vehicle-specific default to provided reference tune.
