May get the Zeitronix Ethanol Content Analyzer but need advice.
So my car runs on E85 and for the winter they switch to e70 i believe and so i need to know when they switch so i can get my car retuned. So i looked into the Zeitronix Ethanol Content Analyzer and im wondering if anyone knows if my a/f will change when they do the switch for the winter ? If it does i really wouldnt need the analyzer. If anyone has any idea please let me know. Iv never ran e85 and im really scared the cars going to run like ****. thanks

AFR (lambda) will be richer at E70 than E85. Assuming you get what's written on the pump. Usually actual E % varies from pump % number.

Yes you can just purchase the ECA itself without the sensor. Compatibile sensors are found here: http://www.zeitronix.com/Products/ECA/ECA.htm

How much do GM ethanol sensors go for from scrap yards? I've gotta think there are millions of them out there... If I find a GM sensor, is there anything else related that I need to take? Wiring harness, etc?
Can the output of this be read by, say, EvoScan, or is an ECA 100% needed?

You can find the GM sensors in junkyards, but if you tell the guy in the junkyard its an ethanol sensor and he notices that the MSRP is around $700ish, you'll still pay a pretty penny for it. Mebbe you can pull the part and tell the clerk is a EGR valve or something like that :P
I believe the ECA has some soft of way to convert the signal from the sensor to analog. So, unless you have a way to convert the signal to analog laying around, then you'll need the ECA

So the sensor puts out a digital signal that would need to be converted to analog in order to be logged, or is it the other way around?

The sensor outputs a waveform signal. 50 Hz = 0% ethanol, 150 Hz = 100% ethanol. The ECA converts the waveform signal to an analog signal that can be read through an ADC input.
