the megasquirt has a 3d map for ignition timing. You need this so that you can run more advance under light loads, this increases fuel economy i think. eg at 3000rpm i run about 35 degrees under WOT, but coasting it runs over 40 degrees.
boost retard can be just done in the boost section (MAP > 100kpa) of the igition map. don't need an extra section.
air temp, and coolant temp corrections are separete.
Megasquirt'n'Spark-Extra or Megaquirt-II is what you need if you want ignition control.

You can even do COP with MSnS-E with the right sensors. cheap way, but don't expect it to be a walk in the park though.
if you want ignition only control look at MejaJoltLite Junior or something.
