Le sent me some screenshots a couple days ago and I intend to do another short video showing what happens to TAS, fuel flows and EGTs at various altitudes and power settings. Hopefully get that up next week.
The numbers in question are the negative numbers where the EGT are (on that EMS). At a point where you reached LOP, the EGT numbers switched to numbers that were between -20 and -40 on each cylinder. What does -20 mean?

As far as the future video, if you can list AFR/MAP/EGT/FF, and IAS(TAS), that would be ideal....

Thanks!!!

Charlie

When using the "Lean Assist" feature, as you continue to lean past Peak EGT for each cylinder, the actual EGT temperature values are replaced by those numbers which show how many degrees LOP each cylinder is.

We don't have the AFR info but will have the other parameters showing in the screen shots. Will try to get that together some evening next week.

Default LOP Video

I put this together tonight. https://youtu.be/6Cf9Pjt-6Vc

Thanks again to Les Kearney for providing the screenshots.

Default Magnet Position Values

In case this was missed on our website:

"We've eliminated the need to set Magnet Position with a timing light on Lycoming engines. For engine using the dual pickup, set Primary ECU Magnet Position to 88 and Backup to 97. For single pickup installations, set it to 92."

Main reasons were to make this an easier install, people didn't like to be close to the whirling prop and many younger guys don't own or have never used a timing light.

Default 2000th Aviation EFI ECU!

Today was a big milestone for us. We shipped our 2000th aviation EFI ECU to a customer already flying with a CPI on his Conti 520. His dual EM-5 is pictured below.



This is very fitting and timely considering 2019 is our 25th year in business manufacturing EFI systems.

We believe that we've supplied more programmable EFI ECUs for Experimental aircraft than all other manufacturers combined. We sold our first aviation unit in 1995. A fair portion have also been supplied for military UAV projects.

We have 3 high time Experimental users with over 2000 hours each on their systems and we estimate the entire fleet has accumulated nearly 700,000 flight hours to date now. We are also proud that SDS is the only EFI system to have won 3 Reno Sport Class Gold Championships.

I want to thank all our wonderful customers who have supported us over the years and made this possible today. We're excited to be working on the 6th generation ECU and programmers which will bring new capabilities and features to this market.

Congratulations Rosa. I can’t wait to fly behind mine sometime soon!

Thanks guys. We're in the middle of new production runs on CPI and EM-5 boards at the moment. Need to get those in process here as they take 3-4 weeks to get loaded and baked usually and that will be slowed down by the holiday season most likely. It's been a good year and these items are running low at the same time.

We've loaded and soldered a few Design1 EM-6 programmers to start getting those out to a few customers next week. Just tweaking software for those and the face plates are in anodizing now. We'll also do a production run of these boards at the automated loading facility along with the CPI and EM-5 boards.

The basic layout of the new round 3 1/8 Design2 programmer is roughed out and that will be next to proceed to production.

Once all that's in process, Barry will get into the meat of the EM-6 ECU design. Realistically, with all this other stuff to do and getting CPIs, CPI-2s, EM-5s and CNC'd parts built and out the door on a daily basis, the EM-6 isn't likely to be released much before the end of 2020. Just too many things to do for our small team to happen much faster. We always want a couple months to do exhaustive testing before we release new stuff and we want to revamp and improve the documentation as well, which is another really time consuming task.
