Hi Wolfgang,

 

My problem is that the VM1000 from Visionmicrosystems is a complete engine Monitoring unit that does not get serviced anymore.

 

All my wiring to/from the unit (inside the cabin) to the sensors (outside the cabin) is sealed in for the pressurization.

 

My amp portion of the system is not working correctly. I would need to buy a different engine monitoring system from a different manufacturer. But the newer systems use different wires for EGT, CHT, TIT – this would then require to change my wiring to the sensors (which would be a pretty big project: removing the panel, pull new wires, seal the cabin again)

What does a thermocouple have to do with an amp sensor ?

 Dear subscribers,
 
After 3 years of work N40941 flew again.
 
Charlie Kohler helped me with the inspection and he also did the first
flight. It was an overall great experience with him and we will also do
more training together .
 
The plenum idea and the engine sealing instructions from Fred Moreno
work very well. The engine runs very cool.
 
There is one problem that I cannot fix:
 
When I rewired the airplane I decided to keep the VM1000 from
Microvisionsystems (I wanted to save money - big mistake!) Most of my
sensors and wires are new now. My Amp sensor dies repeatedly after a few
hours of operation. 
 
It turns out that processor unit puts out too much voltage to the sensor
and kills it. Microvisionsystems (JPI) cannot fix the unit and cannot
sell me another one (dead product).
 
I am a little reluctant to put a complete new monitoring system in
because it would require to rewire everything (obviously the new systems
don't use the j-type thermocouple wire anymore). 
 
My question: do you know anybody that upgraded to a new engine
monitoring system and would sell me the old VM1000 processor unit?
 
Thanks for your help
 
Ralf
