Or you could trade it in for a new UL Power (www.ulpower.com) Model UL350i (same or better performance as the 3300) and get EFI/FADEC as standard. No messing with carburetors, carb heat or carb ice, fuel distribution etc. ULP has also introduced redundancy options for the ECU.   

See: http://www.ulpower.com/ul260i-qa-ecu.htm. Click on link at bottom of page for schematics of optional ECU arrangements.  

   

See attachments for preliminary UL350i specifications and performance. ULP is fine tuning/optimizing the UL350i design with release to the market expected 2Q/3Q 2009.

I'd love to hear any real world results of the AeroCarb on Zenith 601s.  

   

I also personally would love a fuel ejected fully computerized control  

setup for the 3300 as well!!!!!

 Andy,  

 That is a very informative post.   

 I have been testing with a twin injector throttle body feeding an  

 unobstructed plenum, then for comparison feeding the Jab collector. My  

 fuel/air mix should be better, in fact I tried 60PSI for greater  

 atomization, but the charge entered the plenum and too much of the  

fuel

 This is an issue independent of the splitter or the type of  

turbulence.

 This is similar to the principle used by Dyson when dust is separated

 After endless tests I think the problem is due to the fact that we

 I plan to reconfigure my plenum for bottom feed similar to the 0-200,  

but

Just wondering... there seems to be a preponderance of posting on this   

list that has to do with Bing carb   

tuning/jetting/adjusting/modifying/etc. Has anyone considered an   

alternative? AeroConversion's AeroCarb comes to mind :') I'm quite happy  

   

with mine (Sonex/3300/AeroCarb), and I know that there are  many other   

Sonex/3300 drivers that are, also.
