Test Results: Compression vs. Ignition
This is the test engine I started with, for reference. Run-of-the-mill eco four banger: http://www.mediafire.com/?8tjha04twkasb75

Maximum power and fuel economy were achieved with an ignition setting of around 80, while more spark is better for response and emissions. I haven't tried any other engines yet, if I notice a large discrepancy with other motors I'll try to put up those results also. Feel free to post your own tests in this thread, as well.
