Engine Analyzers

[jlunseth]

Yes, sure, wilco.  We put quite a bit of thought into where everything should be located.  The MP over on the far right was not a good idea for example.  I mentioned the strip gauges for the engine functions.  We moved the AP annunciator over in front of the pilot, and the Icarus SAM is also located there.  The display is a button that can show two things, your choice, such as encoder alt., direction of flight, next WYPT, time to next WYPT.  And of course it turns the GPSS on and off with a button push. 

The objective was to get all the critical functions directly in front of the pilot for IFR.  The only thing we did not move, as I mentioned, is the suction.  There is an alarm in the Icarus for that however.

OK I'll continue this thread just a bit. I have been soaking in all the information about analyzers and have been convinced to proceed with either a MVP-50 or a JPI-930. The survey indicated that 10% of you liked the MPV and 13% liked the JPI. I did talk with Dave Campbell at EI and found him very helpful. Evidently you can add on the Vacuum pressure and gear indicators and fuel level module. With these add ons the price would be close to $6000. JPI has a rebate going now and am leaning that way if the basic unit comes with every thing. It appears that the MVP does a little more, so I'm asking for some feedback from those that actually have been using the product. I basically want to replace all the guages including fuel. Your help and advice is appreciated.

Eldon,

Sorry no info on the MVP. 

But I did just install the JPI 830 after reviewing the 830 and 930 models.  I decided on the 830 due to cost and also no need for more panel space.  Just a note after talking to the avionics tech about the 930, he stated "the 930 is a lot more labor".

It is my understanding that if you put in a 930, it is a must to have your fuel sending units removed and overhauled.  I think there may be 2 in each tank, but am not curtain.  I was told the overhaul of each is $150-200 each.  I guess if you don't do this, the fuel gauge option in the 930 is almost useless.

With all this in mind, with price no being a primary factor, I think the 930 is the best option for a very long term upgrade.  But for me cost did not allow it.

I would agree on overhauling the senders.  Mine weren't overhauled, and the readout on the 930 is very pretty but also pretty useless.  The exception is the fuel flow readout, which is based on the fuel line transducer, and that fortunately is very accurate.

Not to sound obtuse, but how do you "overhaul" sensors?  I thought they either "worked" or "didn't work"...

I have a sensor on my JPI 700 that keeps sending a jumping response to the JPI where it seems to jump 50 degrees in temp; up and down.

Fuel level sensors are mechanical devices that wear.  Bushings can be replaced, contacts cleaned, and resistors re-wound as necessary to restore proper operation.  You can replace them, of course, but that often costs more.

[jlunseth]

I think the problem with replacing them right now, might be finding replacements.
