This is way beyond my comfort zone, but I love to watch and learn.
All the best to you Casper, enjoy yourself.

Stay out of Poochies Hooch.

82aspy, you have to be physic man, or great minds think alike. I spent the entire weekend, and its a long weekend up here, as you know ( For our US friends Canadian Thanksgiving is in mid October, if we waited until the US date we would all be shovelling snow) looking at various ECU options. I pretty much ended up at SDS, I liked their approach, a bit more pricey than MicoSquirt, but not near as pricey as some of the bigger name systems. Go on the Bosch EFI site, if you want sticker price shock . Sort of a middle of the road system, IMO. So it was just a couple of hours ago now, I was reading through the SDS information, I was at the point of looking up the contact info as I thought I would drop them a note, or give them a call. First thing I noticed was the (403) area code, that is southern Alberta where I live! Next I noticed their address . It is about 500' from where I will be working on the bike, at my hanger at the Springbank airport. They are in a Hanger just down the road. I can also see it from my darn house, as I have a view of the Airport from my deck. So I figure you can't go wrong with tech support being on the same street. I plan on dropping by this week to have a chat. Weather is still nice here so I will take the bike and let them have a look.

Good call! Hopefully lots of experts to assist you. Very cool.

If I was going to do an FI system, it would be exactly the components you have picked.

I was looking at the bike the other day, and was thinking where the heck I would put a dual turbo set up, and how I would plumb it all in. I had a 2005 Smart Car, with an 800cc turbo diesel, I used it while I was working in downtown Calgary and had to commute each day. Sold it when I retired. The turbo on the engine was not much bigger than a good sized fist. The actual turbo wheel inside is 1.2" in diameter and spins at some 280,000 RPM. I figure it would be a good option for a dual turbo set up on a Wing. But for this winter, I will stick to the Stage-1 normally aspirated upgrade, Stage-2 might come next winter

I took a ride out to the SDS facility today, a great day for a ride in Calgary, nice crisp fall air and wonderful colors in the trees. Put the warm liner in the leather riding jacket, and put on some warm riding gloves, and off I went. A small operation, seems like just two guys. The techie and the business fellow. I was lucky only the techie was there, so I got more of a techie tour than a sales tour. That is exactly what I was hoping for. I got to see all the raw parts and how it all fits together. They had everything I will need, in stock, for the ECU and the various required sensors. I would say their design standards and physical build quality is high. My working background was in the design/fabrication, and installation of special mission aircraft radar systems, so I think I can judge their work fairly well. They have a history going back some 20 years, with lots of systems in cars/trucks and custom aircraft. They never went after the motorcycle market as their ECUs are not designed for 'outside' use. That does not worry me, with the air filter/plenum removed from the GL1000. I can fabricate a sealed aluminum box to house the ECU, to keep it high and dry. Their control technology is simple, the newer style ECU systems have more complicated control algorithms, using higher power and faster onboard computers. My 'read between the lines' guess is they have kept a simple, and proven, approach to best serve the aircraft side of the business, but that is indeed just a guess on my part. I am OK with that, as I do like the KISS principle. Interesting, the fuel injection system in the wife's Piper Mirage aircraft is very old-school, it is a 'simple' continuous flow system requiring no electrical inputs what so ever. So I am pretty sure I will going with the SDS system. Sorry no pictures just yet, still in the early design stages. Going to order the Jenvey TBIs tomorrow. The Randakk Manifolds were shipped today.

Cheers,

Having them as neighbors seems to have really speeded things up! Looking forward to more.

Watching this thread! I've always thought that if I were ever foolish enough to do EFI, this is exactly the path I would take

seeing as how you are going with a seperate ignition systym Pauls C5 the sds would probably be fine otherwise the microsquirt might be better. some has to do with the size of the brain. I was going to use a gl1200 sei brain and complete sei package on a naked bike but the brain basically needs a trunk due to its size............ JB

I did like the look of the Rotax aircraft engine set up on the SDS website, and I think it is a very viable way to put EFI onto an old GoldWing. However, part of the inspiration for going the route I am, comes from the 'look' of the Weber 40DXF installs, such as on; Wang-Thang, Greg's White-Trash and Randall's RC003. It gives the bike a unique custom HotRod look, IMHO. There are alway many ways to 'skin a cat'. In general I like taking proven systems from proven suppliers and just doing the integration, whenever I can. But I certainly do applaud, and support, those who take a more fully custom approach.

It makes feel much better now knowing that I made the same foolish choice that a true GoldWing Guru would have made.

I did look at both the Mega and Micro Squirt systems and was close to going down that path for the ECU. I still wanted to stay with the C5 because I feel the multi-spark will help, on its own, to make the bike run better. SDS does offer systems that also do the ignition timing part, but as with the Mega/Micro units you can also just operate them as fuel control only systems. My trunk will be pretty full, my plan is a drop in aluminum 'box' to provide a dry home for the ECU, the MAP sensor, along with the Wide-Band O2 electronics box. SDS offers their control/display unit in a round aircraft instrument style (3-1/8" Dia) that I will be mounting in place of the fuel gauge on the trunk lid. Also a really big advantage, at least for me, in selecting SDS, is their shop in just a few hundred feet from my shop, so tech support during the install, and more importantly during system tuning, is just a walk away. It may cost me Coffee and Donuts from Tim Hortons, or a few lunches at the local Flying Club's Diner, but I have a feeling it will be well worth the price. While indeed the Squirt's have a very good sized custom project base, in particular on bikes, SDS has been successfully doing the same thing for 20 years in the auto/truck/aircraft world. On most bikes the SDS would not be a good choice at all, as the ECU is not water proof, but with a GoldWing one can install a dry home in the trunk.

As always I very much appreciate all comments and suggestions. I am trying to cover all my bases, but I am sure I will make some errors along the way. Input from you folks will help me make less of those mistakes.

ahh gotcha, ended up just seeing this build and those "looks" certainly do stand out!

The only concern I have with SDS is that the type of crank sensor they use is limited to their system only. At least that's the way they used to be and a quick look at their web site seems to confirm it's still true. Still, not a problem as long as their sensor can fit behind the crank pulley, and there's room to mount the magnets needed into the pulley. This is only a concern if you want SDS to control spark, no special crank sensor needed for a fuel only system.

Btw, the method I show for mounting a coolant temp sensor (in place of the fan sensor) does not really work very well! The method I used puts the sensor on the cold side of the thermostat, so it never reads quite what it should, especially during warmup. Am currently using the stock Honda temp gauge sender, with the gauge disconnected.
Good luck with your build, should be a good improvement over the sometimes tempermental Webers!

Hey socrace,

Thanks very much for the input. I am amazed at the extent of GoldWing knowledge on this site. Whenever I read a thread about various modifications done, as I just did with yours, the imagination and abilities shown are outstanding.

Any more changes to your set-up? Hows the bike running?

I will be using the C5 Optical Multi-Spark ignition system, it has a Tach output that the SDS can use for engine RPM. My EFI setup will be a fuel only, batch-fire system.

I really liked the fuel pump approach you came up with. Has that worked out well for you?

I was wondering how to best install the engine(coolant) temperature sensor. Your idea of using the installed Honda system is one I will see if I can use with the SDS system.

Cheers,
