Zeitronix Zt-2 Wideband Analog Output
I found this on zietronix site, while it does talk about hooking up to Aftermarket EMS's, it doesnt definably answer the question of how it hooks up. From the looks of it online, numerous people have hooked the two up. Question is how.

"2006-2009 Zt-2 Wideband has two wideband outputs. The Linear Wideband Output and the Nonlinear Wideband Output, which follows a natural output curve of Bosch LSU wideband O2 sensor.
The Zt-2 Linear Wideband Output is shared with the Narrowband Output (the Zt-2 purple wire). Typically the engine management systems use only a narrowband or a wideband O2 feedback.

2010 Zt-2 Wideband has one Linear Wideband Output (white wire)

2010 Zt-3 Wideband has one Linear Wideband Output (white wire) which is a configurable output. The default output matches the Zt-2 2010 output and the Zeitronix Data Logger software may be used to configure the output AFR voltages to match 3rd party engine management systems or gauges."

The EMS usually uses a Wideband 02 input, especially the AEM Unit. Narrow band isn't that useful for accurate readings unless we're talking one of the serious mofo narrow bands that the dyno meters use for linear read outs on runs.

If i'm understanding it right, it looks like the Zt-2 has 1-2 outputs(depending upon year) for EMS systems. No idea about the AEM system tho or whether the ZT-2 exports all info given to it by it's sensors or only a select few. If only a few I'd assume the ems would need some of it's own sensors.
