I bought an ESI to monitor my Rotax engine. It comes with a wiring harness that has multiple wires about 18 guage that run to the various sending units being monitored.
My question is before I start hooking everything up. Should the tach wires be separated or put in a shielded cable to Prevent Electro Magnetic Interference.?
One of the major reasons for an engine change was to get something that would have better radio reception .

If it is a E I S system like mine, then no.... just run all the wires together from the engine to the panel.

I shortened my wires and ran them up through the keel so the wires would be be out of the way.

I agree with Ron. On my Air Command, I did nothing special with the EIS wiring, and never had a problem with radio interference.

My radio was an an Icom A4 sport handheld.

Thanks Guys,
Ron,

E.... engine

I......Instrument

S......System

I have not seen a ESI yet.

And yeah I ordered it with extra wire, I didn't want to come up short and have to splice in more wire, so I had them do the harness long and I clipped off what I didn't need. They should have asked you how long you wanted your wires, hope you didn't measure too short!

Also I had them send me the optional stuff to use my EIS as a rotor tach as well.

Thanks for the correction. Its not Electronic System Instrument. Mine came from leaf, I did not know you could order it with longer wiring but I think it will be fine.

Whoops... forget it. I just located their site.
