EFII current
The full system draws a little under 10 amps at high rpm (4 cyl).
Half of that is the fuel pump. Again about the same as AFP+Plasma+boost pump.
The ECU runs down to 7v.
Our system is not a power hog by any means and low voltage operation is very good!

Thank you.

The existing Carbon Cub 340CC application is carbed and has no pump. The Plasma III pulls 1.3 amps per side and runs down to 4 volts. The numbers suggest the existing system will cruise three to five times longer on battery...which is why I figure most customers would want a backup alternator with EFii.

We saw how good when it wouldn't start on the dyno until hooked to a separate battery. Sharing one with the dyno starter pulled voltage too low. The Carbon Cubs's B&C starter also has a larger than average draw. Anybody tried to crank a 340/EFii/B&C combo with a single half-flat PC680?
Of course, there is always the Bus Manager.

The standard Bus Manager installation uses two batteries and one alternator. A two battery, two alternator setup can also be implemented if desired.
The Bus Manager stops brownout during engine cranking!

But we are happy to just accept $64,000 each and throw in EVERTHING!

Thanks. Sometimes I wonder about web designers - seems that there are a lot of websites with critical information hidden in the most unexpected (at least to me) places....

Super Design
Does an electronic ignition make any performance improvements?

Typically, yes. You can go faster at a higher fuel burn or go the "normal" speed at a lower fuel burn. For P-mags the number most often quoted is a reduction of 1.5 GPH in cruise with two installed.

Carbon Cub customers have no idea what is going on under the hood. If they did, they would've just built their own cub, and saved $100k. They will buy the latest gizmo just because. It's the Cirrus of Light Sports.

Seems a little bias is at play here? I've tried to start a stock IO-320 with two Slicks on an Glasair I with a stock Bendix on a half flat PC680 and it didn't start... does that count?

Most conventional batteries have less than 10% charge remaining at an open circuit voltage of around 11.5V. You won't be flying for more than a few minutes when it drops below 9V if you have battery dependent ignition and fuel delivery.
Most critical avionics like transponders and comms will sign off at around 8.5-9V.
Electric fuel pump performance falls off drastically at around 8V.
Inductive system spark energy and injector response time falls off considerably below 8 volts unless compensated for by increasing charge coil charge time and injector on time.
No engine is going to crank over at an open circuit battery voltage of 9V. Any good battery/ starter/ cable setup should be able to sustain a minimum 9 volts@200 amps for 15 seconds. This is a standard load test I've used for 30+ years. If it doesn't, you should find out why and fix it.
I hope nobody is going to go flying any EI/EFI equipped aircraft with a marginal battery- you are asking for trouble IMO. Remember the Diamond Twinstar double engine out incident a few years back...

Greg, you're smarter than me navigating the titan website.
I failed the easter egg hunt - Kevin, can you post a link to the pdf price list?
Thanks!

bummer
It's neat to see the new stuff from ECI but I can't help but give a sigh when I see that in order to partake in it, you have to buy an engine by Titan. Bill isn't going to buy another engine just to get a forward facing sump so now he has to go to Superior who will gladly sell the sump to customers. I'm in the same boat. Same goes to the new unique filter housing and new design cylinders. The innovation is amazing and worth giving you guys a pat on the back.
My discretionary income can yield several Ben Franklin's for these interesting offerings, but not to the order of a new engine. I hope that your marketing strategy will indeed change in the future to allow folks with engine's to purchase things without having to replace an engine.

The entire Magnesium updraft warm sump weights just 7.5 lbs. Not sure what you mean by kit? Gasket and new hoses with clamps?
