Does anyone know if and how the flex fuel gauge outputs a 0-5V ethanol content signal? Within the specs page of the gauge 30-4910 or 30-4911 they state it features:

"Differential Ethanol Content analog output"

I can't find this output anywhere in the manual. Page 4 and Page 5 talk about Boost Analog output and AFR outputs while page 14 states the only two analog outputs are ethanol content and AFR but doesn't state which wires.. WTF..


I tried calling AEM but the guy I talked to is ****ing useless. The tech guy insists ethanol content signal and AFR are the same thing and both come out of the white wire..
Yeah.. how is a simple analog 0-5V signal in a single wire going to tell me my AFR as well as my E85 content?




I called back and talked to someone competent. Apparently they removed that feature. Time to return it I guess..

Not sure if anyone cares but I emailed them and they said they made a mistake. The yellow wire is the 0-5V output for the flex fuel sensor and there is no analog boost output. They released an updated manual to reflect this.
