Im trying to get one of these NEMA 2000 analog to digital converter boxes to play with my Garmin 741XS chartplotter. I have everything on the network and the chartplotter can see the converter box. I am jumping the analog signals off the backs of the gauges and going to the converter box. When the system boots up, the chartplotter sees oil, pressure, oil temperature, boost pressure, voltage, RPM coming from the converter box. The Garmin system will not let me rename the gauges. Has anybody used one of these CX5003 signal converter boxes?

what make is that? I have used the Nolan units with great results -- sorry not familiar with that unit....

I actually ran into one those on a twin engine boat couple weeks ago. Only thing it read correctly was voltage. Not sure what sensors it was designed to use, but has like zero instrctions, and nothing was correctly scaled. Chinese junk.

I'd also suggest the Noland RS11. At least it has options to scale the sensors correctly.

Have you got those Holley systems running yet?

Yeah, running pretty slick with latest firmware updates. Covers all of their ECU models now, even the sniper.

I knew your stuff would be good!
I was inquiring about Patrick getting his Holley systems going on his builds.

I ran the fox electronics boxes from my old 502 mag mpi to my garmin chartplotter. Worked really nice and also had an iPhone app.

i have a small fusion head unit by my steering wheel and it is able to display any info that’s on the chartplotter. Fuel flow came in handy when I was on lake powell.

Not yet. I have the short blocks back from the builder and was going to start with the transom replacement and rest of the engine build on my Scarab when I found a 1/8 hole in the gas tank on my Sea Ray cruiser. Needless to say replacing the tank in that boat took 2 months. Ill be back on the Scarab build this winter though.

The 502Mags have fuel flow?

Subscribing.
