We converted from a Blue Mountain EFIS to a Grand Rapids Horizon HX with their Engine Information System (EIS 6000). We had The VM probes for the Blue Mountain and are using them with the GRT. We bought a Princeton conversion module for each probe in order to use them with the Blue Mountain. We had to calibrate both the Princetons (1/4 tank increments) and the Blue Mountain (2 gallon increments). We had no problem connecting the output from the Princetons to the GRT HX. Since we had calibrated the Princeton modules in quarter tank increments, it was sufficient for the HX. The HX accuracy is very comparable as measured by comparing actual tank fills with what the gauge showed at shutdown - in our ES the comparison is between gallons to fill the 48 gallon tank with the figure: 48 minus the gauge reading.

Hope this helps.

Cheers,

John

I've had pretty good luck with my grt system. They make the eis6000 which is really what the Chelton systems use. I bought their basic EFIS for display purposes. I have not had problems with their hardware boxes or software. I did have to rewire my CHT and EGT probes to avoid shorting.
Anyway, I'm sure they would be happy to tell you if you can use your old probes or not.

Many people have had excellent service with the EI system. But they will probably make you replace all your probes. Again call and find out. I'm sure you won't be the first VM refugee.

Hello to all,

My engine monitoring system is a Vision Microsystems (VM) EPI 800 and worked
well for the last eight years – and still works fine.

I'm thinking of a replacement system – in case of a major failure of the actual system.

My recent research showed that most of the installed sensors are compatible with the
EMS used today.

Fuelprobe compatibility?
Does anybody knows about the compatibility of the VM Fuel probes? I have two of them
installed in the wings. A calibration was done back in 2002 to respect of the Fueltank geometry…

Which system to for?
What are y<our experiences with JPI, Dynon and others?

Any hints and thoughts are welcome, thank you.
