JPI 8/730 Placement

[rogerl]

Santa brought a new toy, see attached photo for JPI730 placement.  Wasn't absolutely sure it was going to fit until unit was received - only thing moved was the go around button had to go down about 1/2".  Installed only with oil temp and oil pressure options, as am happy with the horizon digital tach and shadin mini-flow.

Installer made a call to local FSDO to confirm that indeed the only certified replacements are for the EGT/CHT functions on these units, confirming others' conclusions on mooneyspace.

For the money, both for the unit and the installation, the 730 is a great deal.  The original GEM 602 installation that it replaces cost almost as much, and that was in (1984?) dollars.  So far, the unit seems to work as advertised.

Oh, one installation note: the mounting 'collar' that goes on the inside of the panel to hold the unit in had to be pointed to the right (and reached from the side by removing the sl40), as the screw to tighten the collar could not be reached from below due to the switches/structural bars).

Boy, I want that!  I think I'm going to need to give it a year though to let the sting of the Aspens and the autopilot replacement wear off first though.

If one was not interested in having anything as certified for replacement would it be feasable to buy and install the 740 or is that truly just for experimental?

I was under the impression that that the 730/830 was not certified for any gauge replacement.  It is only supplemental.

I'm in the process of installing the JPI EDM 830 in my M20F right now.  I believe it can replace the CHT and EGT.
