Engine data display on ES78

[Shesby]

I obtained 2 ECI-100s (1 for each engine) and attempted to get the engine data to the MFD again. No luck. Actually get less data coming through with them than without.
I have had a Raymarine certified installer trying to figure the problem out with no luck. He basically has said he can't figure it out but that it should work. He now says the problem must be the engines because he can't find anything wrong with the Ray stuff. He is going to get ahold of the Ray rep in the area and swap out the display to see if that does anything.
I can't get a Honda tech to look at it for at least a week and a half.

Thanks.
