default spark table

[screamer69]

how safe is the default spark table as im running it and the car seems fine but just wanted some feedback on the default map and whats the best way of getting a good spark map

The default MS1/Extra spark map should be pretty safe in NA applications for sure. But as with all parameters, it is up to the user to be sure.
Have you read the "setting up an initial spark table" Sticky ? This gives some good rule of thumb guides.

My map is at the top. 2.0L 4 banger with a turbo in similar size to a t3/t4. I've tuned the spark map up to 15psi boost on 93 octane pump gas. Although, I have about 9:1 compression so you can probably get away with a little more spark advance. It will be a good place to start from though.
