Last update Aug. 11/18
EFI/EI kit for IO-550 engines. Dual ECU. Uses stock throttle body. No wiring shown here. $6969US with all options.
Please note that all SDS electronics operate on 12/14 volts. 28V systems must use a separate 12/14V system or a step down power supply to power the SDS and fuel pumps.
We can now supply quality, fan cooled 28 to 14V power supplies rated for 30 amps. Two are required for dual ECU systems. $165US ea.
Please be aware that there are numerous variations among engines of the same type. Some parts may not fit or may have to be modified in certain cases.
Supercharger in place
Mark Frederick is installing SDS EFI on his 550 powered Rocket in Texas. Fine work.
Andrew Findlay's twin turbo Lancair at 2017 Reno PRS. Dual EM-5 6F.
He also took first place in July in the Experimental Sport Class at the Air Venture Cup Race.
Perfectly aligned CHTs using the SDS cylinder trim function
Andy finished towards the front in several Sport Class races this year and showed tremendous speed in the Gold Race, shadowing the race winning Glassair of Jeff Lavelle for a couple of laps before bumping the mixture knob out of position which cut the engine out for a moment, unfortunately ending his race. With the SDS EM-5 6F system installed, the airplane was much faster than last year, clearly making massive hp in the Gold Race running full boost pressure. He'll be back next year to show what the Stihl Lancair has got. SDS worked flawlessly in the race.
Questair Venture Continental 550 twin turbo fitted with SDS EM-4 6F. At Reno on Sept. 20/09 this aircraft finished third in Super Sport Class Gold at 382mph. Sept. 2010- It wins Super Sport Class at Reno.

IO-550 Installation manual updated July 14/18
Fuel block, Hall sensor and mount, left side
Coil packs mount in old mag holes
Along with the six cylinder engines, we have done a number of smaller Conti engines, the first back in 1996. Mark Snow was an early SDS user on his C-85 powered Dragonfly, accumulating over 750 hours. Justin Mace had 350 hours on his SDS equipped, O-200 powered Dragonfly.
Fuel and spark control kit for O-200. Wiring harnesses, fasteners and plug wires not shown. $4611US for single ECU system.
See the article in the June 2018 Kitplanes magazine on our O-200 system
O-200 Installation manual
Bert Caron is doing an SDS EFI installation on an O-200. With some fin mods, he was able to fit the Lycoming style injector bosses into the Continental heads.
Mar. 15/17. We acquired an O-200 for jigging and development purposes. This was used to design and some new CNC'd parts to make the installation easier on these engines which resulted in our new EFI kit shown above.
Working on prototype Hall sensor mount
Machined up some engine mount hardware to mount the engine on the test stand
Prototype Hall sensor mount fabbed up
Coils mounted in old mag position
CHT sensor mount for starting and warmup
Engine mounted up on test stand
Engine with sump, plugs, fuel pump, starter installed and engine stand support arms fabbed. BMW is used for dead weight to keep the assembly from running away.
New CNC'd bits
Coil pack mounted up to left mag position
Injector mounted to induction elbow
Throttle body in place
Hall sensor bracket
Plug wires and throttle linkage installed
Both coil packs installed with plug wires
Fuel block for O-200
Engine all hooked up on test stand
