I have it working in my RV8 with an Explorer Lite iEFIS circa 2022. Works like advertised. You have to enable flight mode to transmit the black box data to the serial port. Really fun. Fantastic value for giggles per dollar. It’s also an easy way to let a back seat pilot see flight data.
Thanks

My iEFIS lite has been having issues on startup, losing the Hobbs time and other settings. It seems to be getting worse. I removed the back cover and the solder in battery is obviously failed. I’d rather not send it for repair and have the capability to change it. 1) Is the part number available? 2)...

I found a new diagnostics menu on my Explorer Lite for Lite systems. There is a prompt to refer to documentation.
How do I find that?

The iEFIS lite audio out produces a signal that is too high to be connected directly to the V16 aux audio in. A 10:1 resistive divider was recommended by MGL. By adding the network shown below and adjusting to aux audio level on the V16 I was able to get a reasonable audio quality and reduce that cl...

I used the 10:1 resistive divider recommended by MGL and described by LaneRM and adjusted the V16 aux input level to get a good comprise. The audio is still slightly distorted but good enough.

I loaded the data viewer on a new windows 11 computer and it works fine. I find this to be a very good tool. The FWF RDAC allows easy connection of additional thermocouples in the engine compartment for troubleshooting that get logged without modifying your iEFIS screens. I also use flight data view...

Thanks for the scoop. Good luck. I guess I don’t have that problem. I have used a couple of SD cards in my gen 3 iEFIS and they worked with the FAT32 format out of the box.

My V16 works great in my RV8 but I’d like to try the mic filtering of the new software. I’m gun shy about making changes. Has anyone installed it using an SD card through the iEFIS?

Thanks for sharing. My iEFIS lite 8.5” does the same thing.in an RV8. I sent it to MGL Torrance and they couldn’t find a problem.
I have a hunch is a limitation related to the vibration of the panel itself.

I too am struggling with the audio output of my iEFIS lite. The AOA system works very well and would be so much more useful if the vario tone worked
