John,
More good feed back, especially after = hearing about=20 some ongoing problem on the discussion sit ( probably = yours).
A couple of other questions of you , if = I may -=20 within the body of your response.
Hi George,
I've had horrendous problems getting = the EM2/EC2=20 working. Much, if not all, of the problems have probably been to do = with my=20 wiring, not RTFM
 
What does RTFM stand for = ?
 
properly (ie grounding the wrong = wire), not=20 using shielded cable for everything,
 
Is that an Aviation type=20 cable?
 
 not mounting the Program Control = Module=20 properly, long cable runs, etc. etc. After many many months of = sporadic=20 results, I'm still fighting with it. I have 30 hours on the plane, and = I have=20 to say that despite all these issues, the EC2 has never let me down in = flight.=20 Hiccupped, yes, but silence - never. My wiring harness tests = out=20 perfectly, but still no joy. The EC2 won't communicate with the EM2, = and won't=20 trigger a spark. I'll be doing a definitive test later today by = doing=20 what I should have done months ago, and installing my EC2 in Buly's=20 identically configured airplane. THEN we'll = know.
 
Good idea!
 
Despite the severe frustration and delay = caused=20 by all this, I really HATE to consider the alternative of an = aftermarket=20 ECU like the Microtech
 
Well I must say I have some good advice on = the=20 Microtech and it was to leave it alone in relation to Aircraft use. = Don't get=20 me wrong it is a good cheap aftermarket unit for the young blokes = cars, but=20 the mechanics have said they have had problem with a few=20 units.
 
where installing redundancy will be a real = bear and=20 the total solution will be a lot more expensive and complex (read = fault=20 prone). I'd also prefer to continue supporting Tracy's efforts for the = benefit=20 of rotary aviation in general. I think he'd rather be rid of me, = but I=20 just aint going away. :)
 
On the EM2, I much prefer analog input for = quick=20 glance confirmation and trend info,
 
I'm afraid I grown to rely on the analogue = gauges as=20 well, especially so with reduced ( age related) vision - I actually = hired a=20 plane in Tasmania and forgot my reading glasses. All the gauges had = three=20 pointers on landing - had to guess it.
Which bring me to the next question - what = size =20 screen ( big or small) do you think would be best for my poor old = tired eyes=20 and I suppose from reading the garb the LCD screen is the better=20 option.
 
 but its = well worth=20 the cost and panel space to have ALL the data available when you = have=20 time to study it, the graphic access to the EC2 MAP data, and the = range=20 warnings working for you in the background. =
 
Do you think there is a cost savings on = using the EM2=20 as compared to analogue gauges?
 
 
I installed 6 analog engine gauges (coolant = temp=20 & pressure, oil temp & pressure, MAP and Fuel pressure) = alongside the=20 EM2 which allow me to do a scan and also confirm calibration = /=20 sensor failure.  The promised autotune and data-logging features = of the=20 EM2 will be worth the cost on their = own. 
 
Another good idea, I figure they could be = added when=20 finances permit!
