We might consider that if there is enough call for it. Easy enough to use much of our existing hardware.

How complex is converting Rotax 912 from 2 carburetors?

We've sold a number of kits and parts to do the conversion, dating back to 2007: http://www.sdsefi.com/rotax.htm

You have to check each installation for cowling clearance and depending on the manifold and ignition used, you may have to relocate/ remove the coolant bottle and stock ignition boxes.

Ronnie Smith from SMLA has installed many SDS units on his custom 912/914 builds: http://flysmla.com/

Gets rid of the carb synch issues, adds a few hp and allows you to have modern ignition control as well.

Thank you for quick response.

Default Clarifications

I wanted to clear up some confusion some people have about our 2 current electronic products.

The CPI and CPI2 (the latter under development and testing now) just control ignition.

The EM-5 and EM-6 (the latter under development now) controls fuel and ignition or fuel only if you already have mags or another brand of EI. You don't need a CPI if you have an EM-5.

To clarify another question that's cropped up a few times recently, our panel mount, dual connector, 3 1/8 inch programmer can access either ECU on a dual system just by flicking the selector switch for primary or backup ECU. You don't need 2 programmers or have to swap cables. This has been available from SDS for a couple of years now and has a dimmable display when using V29.5 software.



Other misinformation circulating about our 6 dual cylinder systems was saying the engine will quit if one ECU goes down. This is not correct. The engine will run on either ECU, you just lose spark on one set of plugs and the ability to trim fuel. This is a similar situation to losing one mag.

Trevor's Haas VF2s have been churning out new parts for us all through the month of January with a bunch more coming next week. Here's a small sample just back from the anodizer. Feb., March, April are typically some of our busiest months so we want to be able to ship systems without big delays.



Coil mount bases



Fuel blocks, coil brackets and Hall sensor mounts

On another note, we sent off a new fuel pump frame to Tom at TS Flightlines so he can complete mockups of the popular RV layouts to build line sets for people fitting SDS. We're very happy to have Tom as an SDS partner. Great guy, great quality products.

I need a single boost pump also, to go with my stock Bendix RSA. Havent bought it yet, but Andair was top of my list. If you have the capability, not sure why you wouldnt add this to your inventory. Plenty of non-recirculating injections you know.

Not to speak for Ross, but with any business decision it's not just "can we?", but "will it be profitable?"--and beyond that, "will it be more profitable to divert our limited resources into producing some of those than to focus on producing more of our main product?". If pump module production is maxed out on dual units, then making single-pump units would detract from sales of the (presumably more-profitable) complete injection systems.

Same goes for "why won't Van's make a matched-hole RV-3?" that pops up every now and then.

Ross;
I am looking at Duplex fuel valves for the EFI on my high wing (Bearhawk) application. The designer recommends running the fuel valve in "Both", especially for TO and Landing. Andair doesn't make a 4 position duplex valve. SPRL makes one, but the feed is 3/8, and the return is 1/4". Is the 1/4" big enough for the return line on a IO540? I haven't found any other brand valves doing a bit of googling

Because of the significant amount of return fuel (>50% of the fuel feed flow), I think running in R or L is better for most of the flight. But with low fuel,manuevering close to the ground I think "Both" might be a good choice for my application, at least during TO and Landing.

Uhhhh...Yeah. I was responding to his "if we have enough call for it".

So I'm seconding the original call.

FWIW I find Andair to be difficult if not downright unresponsive to deal with. But thats currently what there is to work with.
