A good starting point would be 18 initial and 34 total. Build the curve as a straight curve that has full advance at 3500. You can fine tune from there.
As you said you can develop multiple tunes so to speak to run different fuels etc.
Let me advise you of this... Most people here will tell you to run a lot of initial and have a very quick curve. Most people here complain about detonation and speak highly of low compression engines. So you see a relationship here?
with my MPP dist I had 24 inital 32 total and it was in really quick 1600ish. I run 15 inital now and 35 total in by 3500. Car runs cooler and faster. No changein street manners. If the car has a stall of 3500 what is having the total in at 1500 doing for you?
