Hi Bill,

The HP reading is useless until the fuel flow has been accurately = calibrated and the mixture monitor is operating=20 properly.  Calibrating the fuel flow is sometimes no = small=20 task. I could have made it easy by using an external fuel flow = sensor=20 (the Lycoming version of the EM2 uses one) but that adds over $250 to = the=20 cost.

Have not written up the details yet but have discovered a = big reason=20 why the Mazda injectors appear to flow much more that the numbers on = them=20 would explain when used with the EC2 engine controllers. Steve=20 Boese was very helpful in identifying this anomaly. It's = been=20 driving Ed Anderson and me nuts for some time.

I'm testing a simple mod right now which makes the = injectors=20 flow much closer to what they should. It also makes it = easier=20 to get a smoother engine idle at a lower = rpm.  More after=20 testing is complete.
