Hello Cessna fans,

I have a non-cessna project aircraft (I belong to two other owner groups) which has an early on-board engine monitor installed. The brand is MPI (Masten Products Inc) which is now defunct and I can find very little information about the unit or company. I believe there were STCs for some Cessna models.

I do have the owner's manual, but need more information. The unit does work and seems to have been pretty advanced, including a fuel flow sender and computer. Mine was installed in 1992. Don't know how much longer the company continued.

If anyone out there recognizes this unit and knows of a source (I have tried the usual manual resellers) for a copy of the maintenance or install manual, I would appreciate any help.   Contact info: This e-mail address is being protected from spambots. You need JavaScript enabled to view it
