You didn't see 5 specific items? You don't see any value in having ECU respond when it sees change in crank pulse rate? It normally sees 1 pulse each 100 ms, then next pulse it sees is 200 ms? 100---100---------200---100---100.
If Johns ECU responded any time the engine rpm drops in half, then his risk would be greatly reduced. He would have probably gotten an alarm weeks before this failure occurred.
 
I also provided specifics shared by one of the other posters. The design that automatically switches to ECU #2 when crank signal fails.  I also provided specific solution to Eds plug fouling...the recent post regarding lead scavenger.
 
It only takes 3 private posts telling me to leave, then I'll not post.

Hmm,
I understood Dale without any problem, let me try to clarify it for you Al,
 
You have a tendency to talk in generalizations (and platitudes), rather than presenting a practical solution for an issue that you feel important.
 
Some of your generalization may be well founded, but offer no insight into 'solving' the problem.

At the risk of making a "me, too" posting, I'd like to thank Ed for his
posting.  He wrote almost exactly what I was trying to find a reasonably
nice way to say.

May I add that, if a person isn't on this list to advance the art of _rotary_
propulsion_, or at least improve their own knowledge therein, then their
time would be better spent on whatever they do love.  We don't need
platitudes about how close to the trees we are flying, or generalities
about this risks we are taking.  We need practical ideas on how to
better implement the systems necessary to keeping our aircraft aloft. 

As a not-too-humble example of what I'm talking about.  When Tracy
was bemoaning (okay, that's probably overstating the case) having to
make a bump in his cowl to clear the oil filter.  I went out to the shop
and designed a whole new filter mount that put the filter out of the way,
without the need to add extra plumbing for a remote filter. 
(Unfortunately, my first iteration wasn't a "universal" solution, so my
adapter block has been a much better seller.) 

Platitudes don't solve problems - it takes practical ideas.

However, these postings have sometimes been taken out of context, misunderstood or misconstrued by others in ways not always accurate and sometimes in a clear attempt to put down either the individual, the motor, the technique, etc,  - which is not always pleasing.   But, I won't  let that deter me for posting, I feel I have done my part by raising the issue for others to consider.  Sometimes, I find out from others  that my incident may have a possible cause I had not considered.

Clearly, if a list is not encouraging individuals to post their incidents - no matter how embarrassing it may be (I have a quite a few in that category) - or otherwise not keeping the discussion professional and in a "problem solving" mode, then fewer individuals will post - to the detriment of us all.  

...

I don't think taking issue with a posting - if it contains inaccuracies, or appears out of context, or is intentionally misconstrued is necessarily defensive - just a matter of setting the record straight so that others will have a clear and accurate picture of what happened.  Also, lets face it, e mails are certainly lacking as a communication medium, just too many way to read something - drawing incorrect inferences that were unintended.

In any case, lets all agree to keep posting our incidents - it may save someone's bacon.

Best Regards

Ed
