Have any listers looked at this system? I saw it at EAA NW/Arlington 2007. I bent the ears of both the Precision Airmotive guys and Bart LaLonde at Aerosport about it. Among its appeals are excellent mixture distribution, easy starting, no return lines, self-purging for easier hot starts and seemingly a lot of redundancy designed into the system.
Coming from an automotive engineering background, adjusting my R&D expectations to the reality of miniscule (by comparison) aviation sales volume has proven difficult at times for me. There just isn't enough sales volume to amortize a great deal of testing. Furthermore, I am probably a little more of a flyer than a builder, but there is nothing like an RV-7 and modern avionics available unless one builds it oneself.
Although I generally am uncomfortable with the idea of being a Beta tester, the Eagle EMS has definite appeal. The system appears to be the first common rail/timed fuel injection developed for aircraft engine use. Common rail/pulse width fuel injection has been the auto industry preferred choice for at least 15 years.
Precision Airmotive has had units flying in two different test beds for about 5 years, supposedly without issues. If one wishes to equip a Lycoming (clone) engine with an Eagle EMS the engine must be purchased from one of only three experimental engine suppliers, Aerosport, G&N or Penn Yann. All of these suppliers have stellar reputations. Their selection will provide some assurance of "proper installation." Perhaps this will avoid the "great debate" over whether any problems exposed are installation related, as we have seen with BMA.
At any rate, if you are familiar with this system and have comments I would appreciate it if you would share them, especially if they are "failure mode analysis' type comments.
Thanks,
Larry Tompkins
