SDS EM-6 EFI ECU

Looks great, Ross. I bet it's going to be much easier to read at an angle too. I have mine on the far side of the cockpit, so it's a bit of a challenge.

Really pumped about the closed loop option with the EM6 after learning more about tuning process! Real time/effort saver.

The closed loop option will eliminate a lot of the tuning time required but can only be reasonably implemented using unleaded fuels in our opinion, given the demonstrated variability on the lifespans of WB O2 sensors on leaded fuel to date.

So if you fly locally and haul mogas or can plan your trips to airports selling mogas or Swift fuels, this could be a good option. Whenever we get widespread unleaded avgas availability, closed loop will become the cat's meow for aircraft EFI.

Ross, I really like your new programmer and look forward to implementing the EM-6 on my airplane.

For the fault light, do you provide a discrete output as well? I would prefer to have that fault also show up on my EFIS, which is a pretty simple task to implement if there is a discrete output available.

Thanks for the feedback. I expect that external output will remain for this purpose.

We have dimensions now for the Design1 panel cutout posted on our Aircraft Page for those who've been waiting (about 3/4 of the way down the page). I can also email that info if desired.

Ross - this is a great design. Any chance that you'll come out with a Design1 form factor controller for the CPI-2? I'm struggling having space for the existing controller in my new panel design for the RV-7A.

Not for some time, if ever. We made the CPI-2 one as small as possible and given the lower numbers sold plus time and cost to design and manufacture a second shape, it wouldn't make sense for us at this time. The CPI-2 delayed development of the EM-6 parts for at least a year so it's time to forge ahead now and get it done.

I had a thought last night that perhaps the Design1 could be re-purposed with a new keypad for the CPI-2. This should only involve the cost of a new keypad which would only be a graphics change.

I'll investigate that with Barry and see if there are any other pitfalls in that idea. It still wouldn't happen too quickly as EM-6 stuff has priority but it would make it financially viable at least and speed the process considerably.

Thanks for the input David. Might be possible this way.

Design1 PCB files have gone to the PCB manufacturer this morning.

We are tweaking 2 small items on the enclosure and that should go to machining late this week for production parts.

Have a big box of LCDs and keypads in hand now.

New software for these completed and tested now.

Just have to wait for the production parts to come back to us now.

Design2 LCDs in hand now. Designing the PCBs and keypads should commence by the end of the week.

Just picked these up from the machine shop this afternoon: https://youtu.be/tv6NQlY-MW4

Face plates off to anodizing tomorrow.
