Engine analyzers
Any recommendations (positive or negative) for engine analyzers. To be
installed in a Beech Sierra, IO360-A1B6 engine. What features are most useful, which less so. Is fuel flow per cylinder important? My mechanic likes the JPI. Any specific feedback on them would be helpful. We would install the analyzer for a few reasons: 1. Desire for early problem detection in an engine that is already beyond TBO (the engine was rebuilt, but not overhauled, as a result of a prop strike about 800 houir ago). If things are beginning to go bad, I am hoping that the analyzer will find them first 2. Desire to 'pamper' a 'senior-citizen' engine that, other than age and hours, runs great, great compression, consistent oil use 3. Maybe even save some fuel dollars thru more effective leaning (only have egt now) Thanks in advance for your thoughts |

I'm very happy with my JPI. I originally got it for the reasons you
did, however, what I really like about it now is that when I have a 30 year old factory instrument it isn't working as well as I'd like, I can just plug a sensor into the JPI and have a digital gauge for the same. I've added fuel flow (LOVE IT!!, couldn't live without it), OAT, oil temp. At one point I was tracking down a strange, intermitant electrical issue. Being able to read the exact voltage off the JPI really made it easier to dignose the problem in flight (low charge vs. no charge). The only complaint I have with the JPI and GEM systems is that you are doing a LOT with a couple of buttons. It gets to be quiet a dance trying to figure out all the combinations of things you can do with two buttons, especially once you add more features like fuel flow. Also, I often fly with students who hate their JPI and can't figure out how to make it show peak EGT. The problem is almost always that they have a really old version of the software. Upgrading the unit addresses the problem. Also, at one point JPI tried to make the output of the unit (you can download everything to your PC) propietary. That is now long since history but people will often bring it up as a grip. I don't have as much time behind the GEM system. -Robert pgbnh wrote: Any recommendations (positive or negative) for engine analyzers. To be installed in a Beech Sierra, IO360-A1B6 engine.

My avionics shop wanted to sell me a JPI analyzer. I said anyopdy but JPI, never, ever JPI. They readily acknoweledge they don't like JPI's attitude either and especially can't stand their president but they make good stuff. They do make good stuff but I'll never buy it. |

I spoke to their president once and complained about the fact that
their individual fuel flow unit was less expensive than adding it to my EDM. The company line is that integrating the two is of value, but unless you are running a full 800 with HP it really doesn't buy you much other than to graph them together. However, he took out a business card and wrote on the back that I could purchase the fuel flow addition to my EDM for the cost of the independent unit. -robert Newps wrote: Robert M.

I have the JPI EDM700 with fuel flow and consider it an excellent
instrument. It's been extremely valuable in both pinpointing and isolating abnormalities in cylinder performance. The fuel totalizer is really great on long trips. I have it linked to my Garmin 430 for "fuel at arrival" estimates en route. I also like the "mpg" readout for tuning mixture and headwinds. |

I especially like the feature that shows the number of gallons of reserve you will have at your destination. Once on a long trip with strong headwinds (5 hours!), It was very reassuring to know that after adjusting my cruising altitude, I would have a 20 gallon reserve. |

One of the employees of JPI got on the Cessna Pilots Assoc message
board, CPA provides free aceess to any vendor who wants it, last winter I think and basically told the whole community they were idiots, this went on for weeks. Quit bitchin' about our new proprietary software and by the way EI and everybody else sucks. It was a textbook case of how not to treat customers. There is absolutely nothing JPI can ever do to get my business. Nothing. If I had their **** in my plane I would immediately remove it. Robert M.

I remember that. I don't recall if it was in USNET or in one of the
owner's mailing lists but someone shared some quotes from the JPI rep. The guy was surely rude. I guess I can see why someone would not be happy with JPI. However, I'd not had much reason to talk to the JPI guys and I'm happy with the product, but I'm not buying gas at CITCO -Robert Newps wrote: One of the employees of JPI got on the Cessna Pilots Assoc message board, CPA provides free aceess to any vendor who wants it, last winter I think and basically told the whole community they were idiots, this went on for weeks.

I know the principles behind APS, GAMI and Tornado Alley are very much excited about a new player in the market: Xerion. See http://www.xerionavionix.com/auracle1.html Its shipping now for non-certified installations and STCs are supposed to be comming Real Soon Now. -- Frank Stutzman Bonanza N494B "Hula Girl" (mostly happy with my EDM-800) Hood River, OR |
