We converted from a Blue Mountain EFIS t= o 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 ta= nk increments) and the Blue Mountain (2 gallon increments). We had= no problem connecting the output from the Princetons to the GRT HX. Since w= e had calibrated the Princeton modules in quarter tank increments, it was su= fficient 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 fi= gure: 48 minus the gauge reading.

Hope this h= elps.

Cheers,

John

Anyway, I'm sure they would be happy to tell yo= u if you can use your old probes or not.

Many peopl= e have had excellent service with the EI system. But they will probabl= y 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 Vis= ion Microsystems (VM) EPI 800 and worked

Any hints and thoughts are welcome, thank you.
