non sequential map
 

What do I have to change when going non sequential?
Can I use the standard base map and ignition or do I have to change them?

You will need to tune the fuel map a little. You may need to add some fuel. When I did it I added a little fuel to the PIM table for boost first and then tuned the fuel map with my wideband dataloging. You don't need to change the timing maps.

Since boost buildup below 4000 rpm will be slower, you can increase onboost timing below 4000 rpm.

Detemine the area within the lower left quadrant of the map where your engine goes through when accelerating to column N10.
Add some timing in there for the used P rows from about P11-P20.
2-4 degrees is safe.

Look at the base mod map for that area.

ok, thanks guys ;-)
