Glad to hear about the progress, Chris.
Sounds like you are moving in the right direction.
Interesting problem about the coil, Most
of the time if a coil pops a circuit breaker due to operating load its
naturally at the higher rpm where the coil draws more current.
Are you using stock Mazda coils or the LS1
or? What size is your circuit breaker? Are your coils on separate CB
(recommended) and if so which coil is popping?

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.
