TO: Dynon engineers!!!
Hi Folks.
I installed my Dynon 100 & 120 units (including the data swap bus) in my RV9a 2 years ago, and launched the maiden flight a year ago last July. All was working great. I LOVE the ease of reading, the display size, and the functionality. I am EXTREEMLY happy with the units!
I uploaded and installed 1.08 and 1.07 ... all still great.
I uploaded and installed 3.0 to get the new enhancements, and the following items DO NOT work correctly: :-/
1. EFIS % Power indication is erratic, and doesn't "feel" at all right. Example: I'll be at 2400 rpm and see a 98% Power indication.
2. EFIS "Peak and Lean" indications do NOT correlate to what I am seeing using EGTs as a guide
3. EFIS crosswind and winds aloft overlay on the HSI are really off ... Example: I have indicated an xwind component of 90mph
As a result, my in-cockpit response is that I just ignore these indications.
All of these above issues are neat enhancements, but are NOT required.
It'd be nice if they worked correctly.
BUT the MOST (!!!) important indication that I CANNOT ignore and that has changed is:
4. The EMS Carb Temp that WAS funtioning correctly prior to 3.0 ... NOW reads a constant -27 degrees, and it never changes.
With winter coming, I need this fixed ASAP.
I would seriously consider reverting to the 1.8 and 1.7 versions, hoping to restore the correct Carb Temp indication, and to remove the 3.0 enhancements that DO NOT function correctly.
I am willing to receive any Dynon help or assistance on this.
Also please note that I am NOT a computer whiz ... but can follow simple directions.
Therefore, I am also willing to schedule a time to sit in the aircraft and push buttons as prompted, to trouble-shoot these issues.
And ... here is my engine type and equipment:
Aerosport Power 0-320
MS carb
1 slick mag
1 p-mag
Fuel flow meter
Thanks in advance for your help and response!
