It all depends, Henry Ford built the "best" car he could when he built the Model T, a 1962 Chrysler 426 Hemi would have really seemed like magic to Ford and a modern double overhead cam engine in a 2000 Acura would really would out perform that 426 monster cube for cube. Huh? GAMI is better than stock FI which is a very old, low tech constant flow system on Continental and Lycoming engines. Your car uses high pressure pumps a fuel rail and solenoid control metering at the injector, but engine roughness is caused by __________ which causes __________ vibration. Do you have any idea what GAMI injectors are? |

answered at the top, Yes.
But most engines do not have them or the same procedures that they allow.

Leaning (was Gene Whitt is back on line)
Jim,
Peak power is max RPM, some books recommend running richer, enough to drop the RPM 50. Do you have an example for a POH recommending that? And do you think this procedure prepares your students for complex aircraft adequately? -- Thomas Borchert (EDDH) |

Jim,
I think we are saying the same thing, basically and to a degree. Nope, not at all, I'm afraid. Different power per cylinder will be rough, but as long as the output is close, most pilots won't notice minor variations. I used the word misfiring to indicate what was happening that would be detected. There is normally no misfiring at all in an engine running rough from leaning. -- Thomas Borchert (EDDH) |

But most engines do not have them or the same procedures that they allow. You are talking in circles or something, since damn near every response of yours on this thread is virtually unrelated to the question asked, or the fact posted. First of all, very few FI engines are calibrated coming from the manufacturer, especially TCM engines. Second, GAMI's are nosels, not injectors per se. Roughness is NOT caused by a misfiring cylinder, but by an improper fuel distribution. All cylinders can be firing just fine, but if the air/fuel mixure is out of balance, it'll be running rough. |

Matt,
