    Dual Buss, EMS volts and Lightspeed questions

    I have been struggling with the dual bus decision as well--your plan is to power each screen independently? How well does Dynon's internal power distribution handle this scenario?  Say for instance one bus (and one screen) is 14V and the other is at 12V--are there diodes to protect from...

    Simplified autopilot addition?

    I'd venture that all pilots--technical people or not--know the difference between heading and track. Duane also makes a good point about previous generations of autopilots.  Every autopilot I've ever used had heading hold, and only the fancy ones could fly a track.  I'd suggest that people...

    SkyView External Dim - Ok to use PWM?

    If my programming voodoo is up to snuff, my plan is to have 0V default to max brightness. The dimmer knob has an on/off switch at the very bottom end of its range--I'd like to leave it off during the day, and have that command max panel brightness. Hopefully...that means if the dimmer...

    SkyView External Dim - Ok to use PWM?

    Just wondering if SkyView will function with an external dim signal from a PWM dimmer...or if it actually needs a specific voltage input. Thanks!

    Out of serial ports - anything I'm overlooking?

    I'd like to add a serial out for telemetry, but I'm out of obvious options.  I was hoping for a second opinion to answer the following questions: [list bull-blackball]Can I steal the TX side of the port from either the SV-ADSB-470 or the SV-GPS-250? If so, I'm pretty flexible on baud rate (I...

    Help with EMS pinouts - custom sensors, SDS EFI

    Ha! Sounds like I'm in for a bit of a redesign. I was using the kit harness as a starting point and it never crossed my mind to completely isolate the ECUs. Time to get smart on how SDS deals with ignition coils! Although I have considered the aux battery plan, I'm drawn more to having two...

    Help with EMS pinouts - custom sensors, SDS EFI

    Hi mmarien!  Your posts on this forum have been a great help and inspiration for my system--thanks for blazing the trail! It's an EFII dual ECU kit with some modifications. The airplane's mission involves flying over hostile terrain, so I've tried to design in as much redundancy as possible. ...

    Help with EMS pinouts - custom sensors, SDS EFI

    Wow, thanks for the immediate and detailed response.  You guys are awesome! It looks like Kavlico makes an appropriate sensor (PTA5000-3000-2-B).  Now if I could just find someone who sells it... For anyone who's curious, here's what my pin table looks like: 1. Left Bus Voltage 2. Right Bus...

    Help with EMS pinouts - custom sensors, SDS EFI

    Hello! I have an EMS-220 with an EMSKIT-L4F probe set that's going on a Lancair 360.  I'm sketching out what pins to use for everything, and I'm out of ideas. In addition to everything in the probe kit, I want to install the following: [list bull-blackball]Left Fuel Quant: VM probe with...
