FI Ignition

panteradougMember

OK. Things are moving along in my planning stage.

In previous discussions the subject of engine management systems was briefly touched.
Some have suggested to use a ECU that controls both ignition and fuel.

Dan Jones mentioned that there is software that blends MAP and throttle position. The reason being that neither system was optimum for either economy or performance alone.

If that is so, with an IRFI system, what would be the best to consider for ignition? Would a mechanical advance distributor now be obsolete?

With the ECU Ignition control do I just plug in an adapter and then all ignition advance is taken care of by the ECU, i.e., the initial advance, total advance, rate of advance? This would be set in the software and for the sake of discusion I could have 36 total advance at 3600 engine rpm and
28 degrees at 3601rpm?

I have a feeling that you guys with the running systems are running on the "as delivered" software maps. Can someone tell me differently?
