Hi Bill,
The HP reading is useless until the fuel flow has been accurately
calibrated and the mixture monitor is operating
properly. Calibrating the fuel flow is sometimes no small
task. I could have made it easy by using an external fuel flow sensor
(the Lycoming version of the EM2 uses one) but that adds over $250 to the
cost.
Have not written up the details yet but have discovered a big
reason why the Mazda injectors appear to flow much more that the numbers on
them would explain when used with the EC2 engine controllers. Steve
Boese was very helpful in identifying this anomaly. It's been
driving Ed Anderson and me nuts for some time.
I'm testing a simple mod right now which makes the injectors
flow much closer to what they should. It also makes it easier
to get a smoother engine idle at a lower rpm. More
after testing is complete.

"Doesn't have to be long, doesn't have to be prose, doesn't
even have to
be the truth - just write and make some outlandish claim
- like 250Hp at
4200 rpm {:>) or the unbelievable efficiency of
pinched ducts - that'll
get some attention."
Hey! I didn't
build the instrument...I just read the numbers off of it!
Heck!
I don't even know how it works well enough to understand why it
reads
so high!!?? :>)
And I still think it looks good!
