IGN Advance under Ignition
The IGN Map's under IGN Advance are used in the Map Index above for the Cyl1, cyl2 gear map etc.. Example. When you click on Cyl 1 gear Map Index, those numbers for each gear are referencing the IGN Map number under the IGN Advance. Each gear can run its own map or you can call out the same map for all gears if you like.
