I'm curious if there is any way to hook up an OAT probe on pin 6 of an EIS-4000 vs the Carb Temp probe that is shown on the diagram? I'm asking since I've used up all my AUX ports, and OAT is currently not in that mix. I've got a Long-EZ with the EIS mounted just forward of the firewall vs my EFIS ...

Great! Thanks Jeff.

Since the HPS-SS-01 comes with 3 wires and a bare shield in a black sheathing, just wanted to confirm that it's ok to cut the wires and bare shield shorter?

I'm building a pusher aircraft so the fuel pressure sender will be just on the other side of the firewall from the EIS4000 unit and I don't ...

Jeff,

I'll give it a try when I install it all and see how it works. My Electroair controller will sit within 8 inches of the EIS4000 control head, so no real pain in the physical wiring. If it works, great. If not, we tried. Thanks for providing me the settings to try it out.

Bob - Understand ...

Bob, I would like to know my spark advance on whatever EI it can be measured/displayed for, but I've never thought about wanting to know it out to a decimal point. Any discussions I've had or been privy to on discussing engine timing has always been regarding a simple integer number. But I certainly ...

Ok, more inquiry here since I got an answer back from Electroair.

Here's the statement from Electroair: the spark advance feed "is going to just produce a voltage in the range of 0.0V to 0.50V. The voltage output corresponds directly to the spark advance angle. For example, 0.25V equals 25deg BTDC ...

Awesome, thanks Jeff!

Is the GNS480 RS232 connection wired to both?

No. It's wired to the HXr, but not the Mini-X.

If it's only wired to the HXr, make sure the HXr is configured to Send GPS Data over the link (SET MENU, General Setup, Inter-Display Link).


It wasn't. Fixed.

In the common case, where the GNS480 ...

I'll be installing an Electroair electronic ignition on my engine that has a wire lead coming out of the control head harness for a spark advance meter. In talking with Electroair, apparently seeing the actual spark advance is out of vogue and they no longer sell the meters, which I immediately ...

My configuration: HXr, Mini-X and GNS480.

The issue I'm having is viewing an external flight plan on the Mini-X that was entered into the GNS480 and is showing up on the external flight plan view of the HXr. The HXr handles the external and internal flight plans as outlined in the manual. However ...
