Other Aftermarket Electronic Fuel Injection
 

I see the EFII question/review listed below (and see they are a sponsor). I?m a several months from getting my engine and started wondering if anyone has used any other electronic fuel injection systems? My current plan is to use a carb on the engine. Has anyone fitted a Holley aftermarket EFI or something similar to an aircraft and had any success or failure with it? Maybe I just haven?t kept up with reading my airplane magazines lately?? Or maybe I need to ask the order of magnitude cost of the EFII system for an O-360. Thanks!

Thanks Mike.

I was the Crew Chief for Mike Dacey. We used Ross's system on "Bad Intentions", a Questair Venture (highly modified). The Continental TISO-550 stock fuel system could not deal with running at 3,000 RPM and over 65" of boost. It required Mike to play with the mixture knob when going to high boost. No adjustment would work at high and low boost.

We put the SDS system on the aircraft and it turned it into a two lever operation, throttle and prop. We could control fuel flow so that EGT and TIT's stayed within normal operating limits from idle to full race power. (Estimated at around 700- 750 HP) We used ADI in large quantities to keep it from detonating.

To use the SDS system, or any other EFI in an aircraft you must have a backup fuel pump and a second battery. There is a simple way to keep the engine running even if the EFI system fails, but it requires fuel pressure.

We never had a single issue with the system. Once tuned, it was the one thing we never worked on.

Thanks guys!

Hi all,

I'm pretty new in the forum, I'm coming from Italy and I just started an RV7 QB.
I'm through the diffucult engine choice process:
I'd like to have a 360/370 fuel injected but, due to the high fuel cost in Italy, I'll run on Mogas.All of the people installing a classic mechanical fuel injection and running on Mogas are experiencing very difficult hot start due to vapour lock.
I'm seriously thinking about installing the EFFI ignition and injection system.
Do you have any suggestion and report about the affordability of this system?
Am I right or not about that just few of the Vans community installed such kind of system?Except for the cost do you think is a good choice for my new engine?

Thanks

Good to have you aboard :D

You really only need to look at Airflow Performance.
Hot starts are a none issue with their purge valve.
The system is fully mechanical and has been around for many years.

Ernst,

Do you basically consider mechanical injection safer that electronic?

Not really, just simple and inexpensive.
In addition AFP addresses one of your main concerns,
Vapor lock on start up. The purge valve on the AFP is designed
Specifically to deal with the hot start problem and is aproved for
All kinds of fuels,avgas, mogas with or without ethanol.
It has a long proven track record and Don Rivera, the owner of AFP
