Has anyone been able to get voltage/e85 reading. Basicly looking for a spec sheets?? I want to add the sensor to the EMS

for the siemens sensor yes. The signal is a 5v square wave with the frequency representing ethanol content (50-150hz = 0-100% ethanol) and the pulse width representing fuel temperature (1-5ms = -40 - 125C) they are both linear.

You need to build a frequency to voltage converter and run it to a spare ADC on the ECU.

Also zeitronix already has a nice unit that does all this already, theres a thread on it here

Mike, are you looking to do some sort of auto-compensation with the AEM?

Zeitronix ECA has 0-5V analog output corresponding to ethanol concentration (E%)

Does that sensor sit in the fuel? Looks like i'll be buying a zeitronix gauge when I'm ready to convert to E85 Thanks for the info.

Zeitronix

Yes, the sensor mounts into the fuel line.

I'd love to see pictures of one installed. So the fuel line loops into it and out. That is weird, and a tad of a restriction.

It does not create restriction on a return line
