This is great data. Thanks for taking the time to do this, especially by taking the time to get real data with o-scope samples (Ham Radio op here, so I truly appreciate).

It's a shame BMW didn't augment the sound at rest. It sounds like getting anything decent out of the BMW stock system is unlikely, but I personally appreciate your ability to gather good data as you continue to test and tinker!

Regarding #8, it is possible to rev the engine in Park after you turn the vehicle On by kicking down the gas pedal to the floor. It should start and stay running in Park. I needed to do this in order to have the emissions facility test my car via OBDII. The test wouldn't run without the combustion engine working. Upon start up, it worked fine. But it sounds like your standard Geo Metro 3 cylinder. No sound augmentation.
