MGL Avionics User Forum

As a test only, I screwed the SP7 to a large piece of wood and put that in the baggage compartment behind the rear seats. This is a little behind and above the center of rotation, but still very close (~30 centimeters), and connected the device using an extension cable. During some tests the SP7 see...

thanks for the detailed reply. My iEFIS is showing correct airspeed and true airspeed as well, but I will check the double flash LED on the SP7. I will also check the mount of the SP7 or otherwise move it around and do some test flights to see if I can get any better results. Will update this topic ...

Hi, I am testing my new MGL setup and have some issues with the SP7. I couldn't find anything similar on this forum, I hope people can help me out. While testing during a test flight when I bank (+/- 30 degrees or more) the virtual horizon starts to bank but then quite quickly levels back off again ...

Hi, I am installing my MGL (ibox + iEFIS challenger) system and trying to test as much as possible in the simulator. It seems there is a function for the digital inputs that is labeled "EFIS Audio On/Off". I am wondering if this is a "toggle" function or whether high means "audio-on" and low means "...

I found out that the active is high or low only is applicable to the function that is selected, but not to the alarm.
Apparently the alarm is only/always triggered when the digital input is high, but the function that is selected is executed depending on the active is <state> that whas choosen.

Hi, I have a device that pulls a line to gnd which I want to trigger an alarm on the iefis using the ibox digital inputs. To test this I installed the simulator and configured the digital input and configured "Active level is low" and enabled the alarm. However, the alarm is triggered when the input...

Thank you for the answer. I assume this is done because if the fuel flow sender was installed before the fuel regulator the reading would be less acurate/useless since it would include the flow from the fuel return line ? I think it makes sense to install it into the carb feed, however the fuel line...

Hi, I am installing the MGL fuel flow sender but don't know which Jet size to choose for my engine. My engine is a Rotax 914, burning aprox 20l in cruise. I am a bit confused by the Jet sizes and the flow ranges. Is there anybody who can give any advice on the correct jet size for a rotax 914? Thank...

I am preparing the installation of MGL avionics and had the idea to connect some alarm signals as analog inputs so that they will be displayed at the screen with a good name/description and drive an external alarm led. One of the things I planned to connect is my Rotax 914 TCU warning + error wires....

Thank you for the very detailed explanation!
