Ignition system

[carsounds_dan]

Hi,
Just looking more into the idea of fuel injection for the sv and need to find out some stats on the ignition system... anyone know much about it?
I need to know things like at how many degrees BTDC the ignition fired. Also does the tacho get an input off of one of the coils? if so which one and how many times does it fire in each engine revolution.
cheers

not sure how much but there are basically 3 different curves depending on throttle opening.usually I lock it in wide open curve.
