Tom---In the 1 case that i'm VERY familiar with, yes the cube was sent back to EI for testing. According to the owner, he reported that EI passed the cube with 'couldnt find anything wrong with it'. He reinstalled it; same situation. We moved it---again---same situation. He purchased a new unit, went back over all the wiring to quadruple check things, same situation.
With all the other options having been eliminated, we came up with the only other common piece to this whole thing. I spoke with another build at OSH and he stated he had a similar anomaly, different numbers, but similar. There was 1 common thing between both aircraft.
So I'll put this out to all that have a FT60, inhopes that we can finally put this to bed. Has anyone had an anomaly where in cruise flight, with all engine paramenters (RPM, EGT, CHT, MAP, FP) being VERY steady, have you experienced the fuel flow to take a drop from, say 6.5 gal/hr, to say 4.7 gal/hr, and stay that way for a period of time, and either return to a more 'normal' reading, or after engine shutdown and rebooting, the readings return to normalfor a period of time, then repeat?
IF SO---I'd love to hear about it along with pertnant information, like engine, injection system, avionics, transducer location, and whether any other strange occurances happen. WE think we have a common thread, but would like some more data.
