Hi Bill,

The HP reading is useless until the fuel flow has been accurately=20 calibrated and the mixture monitor is operating = properly. Calibrating=20 the fuel flow is sometimes no small task. I could have made = it easy=20 by using an external fuel flow sensor (the Lycoming version of the EM2 = uses one)=20 but that adds over $250 to the 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 would=20 explain when used with the EC2 engine controllers. Steve = Boese was=20 very helpful in identifying this anomaly. It's been driving Ed = Anderson=20 and me nuts for some time.

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