Re: baro and transponder stopped working

Some findings from a weekend debugging/troubleshooting: - when power from the ibox (v2) removed I can change the baro pressure on the iefis, but it jumps back immediately when the ibox is powered on. - removing all the can connectors from the ibox doesn't make a difference - the 440 messages seem to...

baro and transponder stopped working

Hi, Because of personal reasons I didn't fly for +/- 6 months and my airplane was in a dry hangar all the time. A few weeks back I pulled the plane out of the hangar for a flight but the efis displays a big red cross over the transponder (trig transponder with mgl interface) and rotating the baromet...

Re: SP7 leveling off in turn

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...

Re: SP7 leveling off in turn

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 ...

SP7 leveling off in turn

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 ...

EFIS Audio On/Off function

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 "...

Re: digital input not working as expected

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.

digital input not working as expected

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...

Re: Fuel Flow Sender Jet size for Rotax 914

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...

Fuel Flow Sender Jet size for Rotax 914

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...
