Chris,
The only thing I can think of that might cause this
problem is your battery / charging voltage. Are you running with your
alternator on? What rpm does it start charging?And what is your battery voltage
at the low rpm when it trips?

Wow, apparently real life progress. I have
had trouble starting the engine. I would seem as if the coils would just stop
working. Well, they were. I had a bad wire at the coil switch. It is still
hard to start but I just did a search of the of the achieves and will be reading
those in a bit. The search on surging is proving very useful.
Ok, here is the problem though. A
question for the more electrically savvy. When I get the engine to a
low/very low idle I am tripping the coil circuit breaker. It does not seem
to be a problem at mid idle to high RPM. It has been consistent. I don't
even know where to start. Thoughts please.
I got it close to 6000 static today by
advancing to full throttle, flattening out the prop and adjusting the
mixture...couldn't hold the plane with full brake so I pulled back. This is
on a newly built 2nd gen turbo block (currently w/o turbo) with a medium
street port and a Mistral intake, Tracy's ECU, EM and 2.17 PSRU. The
engine was built by me, but the street port was done by Mazdatrix.
The surging is being brought under control with
tuning. It does seem that I have to hit the program button a few times to
get it to actually recognize the change, but it is changing. I briefly
tried auto tune, but it went from smooth to surging....don't know if I have it
close enough for auto tune yet. Temperatures to reach my max, while
sitting there on the ramp but it is taking a while. I am actually pretty
happy with cooling right now compared to the past. Also, when shut down,
the engine is just sitting there...no leaks, now weird hissing or moaning
<g>. It is just off. Kewl.
All the best,
Chris
