I'm starting to think I may have a good reason to run all 4 injectors at once, unless Tracy adds a feature to compensate for mismatched injectors.  Mine should be fairly close, but the secondaries are farther upstream, so they won't have as good of an atomization effect, and they're also a bit smaller.  Now how do I tell the EC-2 to run all 4 at once...

Rusty;

The normal mode for the EC-2 is primaries only below the stage point, and both primaries and secondaries above the stage point.  If that’s not what you’re getting, check your wiring (again).
