Found a gold mine of information. The 379 and 394 seem to be exactly the same, but one has longer fuel hard lines.

Could the gauge be "spliced" into the DT FF flex fuel sensor or would I need to run another Continental sensor in serial with the DT FF Sensor?

Nothing wrong with their product, but if you want the real time display I'm not sure why you wouldn't just buy our kit to start with then versus using that one? It would be cheaper and you'd get the AN lines by default with no upcharge.

We do have the rear o2 option as well for those that prefer that route and the slightly easier installation. You may find it cheaper to sell your old one and just get ours that is ready for what you need.

Mike, sorry I tagged you without real context, I thought I had mentioned something after I did it.

We're trying to see how we can integrate the Innovate ECB-1 with the flex fuel kits and I tagged you to see if you've managed to figure out how this would work. We're trying to clean up the interior and not have 50 gauges for various data.

I'm looking at the sensor and I see three pins, which gives me the feeling that we're looking at power, ground, and data. Obviously the flex fuel sensor is already getting powered by your (or their) kit, so maybe Y off of the sensor with just the single data line going to the Innovate gauge?

No problem. The sensors all output a frequency, and the ECA/modules all turn that into a usable 0-5 signal. Only differences between the units is where they are made, grade of electronic components, and some additional filters that make for a more stable signal. But you have to have some kind of a frequency to voltage converter to give the gauge the signal. Gauges with integrated ethanol content analyzers should be able to use any one of those GM/Continental based sensors.



The ECB-1 appears to be just that, so you should be able to piggy back the signal from the sensor, but there may be some interference issues so a separate sensor may be needed if you see a change in the ECU rear o2 voltage input on the datalogs.

And to expand on this, the GM sensor seems to have one sensor wire...how does the ECB-1 get both ethanol content and fuel temp signals from one signal wire?

I did some pretty heavy reading and have more information now. The three lines are exactly as I assumed.

Vcc = +12V in
Vout = Output
GND = Ground

To answer your question, this is what's involved in the Vout signal:

The sensor output is both frequency and pulse width.
Ethanol content is output as a frequency of 50-150Hz. The math is:
E% = Freq - 50
180-190Hz means water contamination.

Temperature is output as a pulse width of 1ms-5ms. The math is:
Temp(c) = (41.25 * PW) - 81.25

There's mention of a pull-up resistor possibly being required to bridge between Vout and Vcc. Looks like rigging up a cable would be pretty straightforward. The Delphi connectors are readily available on Mouser to do this the "right way".

Awesome! Thanks for the info. Any concerns with tapping the signal wire from the Continental ethanol sensor and degrading/interfering with the signal going to the repurposed rear o2? As you said before, if this works, it would be an elegant solution vs. having a bunch of gauges.
