Subtleties of ECM tuning
Following are three graphs that show some of the subtle differences in tunes. These are spark advance vs rpm vs air flow, just one on many that make a full tune.
First is a stock tune for an NA Solstice. Note the jaggedness.
Second is a performance tune. Note some of the values or boundary conditions are changed, but the graph is still jagged.
This is a more refined performance or dyno tune. Note the smoothness.
