Flexfuel Temp problem

Post by zed65 »

I'm having some trouble with my flexfuel sensor.
It reads the etanol content just fine but the temperature gives me headache.

The signal from the sensor needs a pullup resistor and after that the signal looks like this:

But the signal needs to look like this for temp reading to work.

Can we flip that in software or do we need that on hardware?
