Default SDS EFI in 2020

Many thanks to all the VAF members who placed orders with us last year and I hope everyone on VAF has a healthy and happy 2020.

So far this year, we have an order backlog of around 14 days presently. CPIs are sold out at this time, more PCBs are in process now at the loading and soldering facility. We expect those to ship to us around Jan. 21.

More EM-5s are also in process with the CPIs and we expect those to ship at the same time. We probably have nearly enough of those boards to carry us through to that time.

We have a good supply of CPI-2 components on the shelf.

Default Service Bulletin

We've seen a couple instances where temp sensor wiring has been tie wrapped to spark plug wires. This should NEVER be done and has led to ECUs being damaged. No EFI/ EI wires should ever be touching spark plug wires. Maintain at least 1 inch clearance.

Default Airflow Systems A/C Flywheel Drilling for SDS Magnets

Adrian Port from Tasmania was kind enough to put this page together on how he did his install here: http://tasrv10.com/?p=2822

We have a special drilling jig for these to compensate for the slight differences between the AFS flywheels with serpentine drive vs. the SDS or factory Lycoming V-belt drive flywheels.

Thank you Adrian.

Great info to have and very timely. About to work with Penn Yan on the engine build (with SDS of course) and Synergy Air South on the Show Planes Cowl and AFS air conditioning. All of these "off the reservation" mods are time consuming and sometimes quite challenging, but hopefully, very worthwhile.

Krea, I have your dyno test harness done now. Just wanted to be sure you have the proper drilling jig for the AFS flywheel. Yours should have 3/16 holes. Let me know before I ship this other stuff.

Outstanding customer support as always from SDS. Canít wait to get this engine assembled and running.

Default Design1 Programmer Upgrades

We've had tremendous response for the Design1 programmer and have had a number of people ask if their older EM-5 ECUs can drive these.

The answer is yes if you send them in to be reflashed.

We have some discounted prices on these programmers for those who purchased complete kits after Dec. 31/17 and would like to upgrade.

People who own SDS EM-5 ECUs or re-branded EM-5 ECUs purchased prior to this date, we can still upgrade you to the Design1 programmers at a higher cost.

We are building as many of these programmers as our busy schedule permits so it may take a bit of time to fill all the orders. We appreciate your patience here.

For those who don't have the individual cylinder fuel trim, PC data logging or digital fuel flow output options on their earlier EM-5s, any of these features can be added to most (check with us) when your ECUs come back for re-flashing. Costs apply and for the fuel trim, you'll need to shuffle some wires on the injector drive harness (16 pin white connector). We can supply instructions and a pin extraction tool to do that job.

Default Design2 Programmer and Engine Temp Sensors

Given the amazing positive response for the slim, rectangular Design1 programmer, we've decided to delay the design process on the 3 1/8 round type replacement (Design2) until after the EM-6 ECU design is completed due to the likely low demand for this package shape in the majority of today's panels.

This will allow us to concentrate all available spare time and energy into the new ECU immediately.

On a second front, we've had two customers who've reported intermittent problems with their CHT sensors. These sensors typically see under 280F in flight and under 320F in heat soak conditions after hot shut down. The solder and potting compounds are both rated at over 430F but the reports say the potting compound was separating.

We've now gone to a single design for both air and CHT sensors where the brass body is drilled right through and the thermistor and potting compound project through the body forming a mechanical lock on both ends of the body to prevent separation.

We're also investigating increasing the curing temperature and duration during the manufacturing process to improve strength and temperature resistance.

I'll be evaluating a different potting product as well later this week and we'll settle on which one performs best after testing back to back.

If anyone sees intermittent CHT (ET) readings in the Gauge modes, let us know and we'll send out the latest type replacements at no charge. These are really only used for cold start and warmup enrichment phases. The ECU doesn't use them once the engine is over about 150F.

Be sure the sensor leads are supported from movement. Physical loading on the leads isn't conducive to durability.

The new sensors also use Delphi connectors which have proven to have better reliability than the white or gray connectors supplied in 2017 to mid 2019. We'll supply both genders to make the change there as well if you have the earlier type.

Default Website

One of my customers said he was unable to see our Home Page for the last couple of days. Sure enough, I tried to view it today and there was nothing there at all, not even a 404.

Was my fault after updating it a few days back, the FTP did something wonky and I didn't check after the upload. The server was showing the file uploaded but 0 bytes there.

Anyway, fixed now and no other pages were affected.

I think most folks here probably enter through the Aircraft Page so you may not have noticed.

Sorry if it inconvenienced anyone.

It's been a crazy week with ECU re-flashes and Design1 programmer upgrades.

I'm hoping to find time tonight to shoot some updated programmer pix in my studio tonight to get some current programmer photos up on the Aircraft Page tomorrow.

Thanks for all the support from our customers on the new programmer design.

We received our new batch of EM-5 ECU boards yesterday afternoon from the loading facility.

More 60mm throttle bodies are out of the machine shop and anodizing now too and we got a new shipment of coil packs, fuel pumps and injectors earlier this week. We'll be able to continue filling system orders again today and try to clear our backlog.

We shipped a Design1 programmer to Stein so they can finish laying out a few panels for customers too.

Have some new videos I'm working on in the evening that I hope people will find interesting.
