Default Megasquirt Spark timing maps?

--------------------------------------------------------------------------------

I've been working on my fuel maps and I got the car to run a clean 11.5-12.2 air/fuel ratio throughout the rpm band at 12 psi. How does the stock spark timing map do, is it extremely conservative and is there any room for more power? I considered running megasquirt pnp closed loop/static timing at 14 degrees BTDC with 93 octane? Suggestions, any body got some good spark maps for a 12 psi 97' Miata?

Dont touch the spark map until someone who knows what they are doing can tune it on a dyno, just like savington told you the last time you asked.

Not sure what kind of gas you run over there but on average many people here get away with 3-4* throughout the boost portion of the map on 93 octane without any dyno tuning.
That does not mean it will be safe for your car. Be careful.
