Flex fuel sensor custom input conversion values

Post by B18CR-X »

hi,
I've got a s300 v3 and have a GM flex sensor connected up, I have set up analog0 input to custom and the type to percent.
what is the right custom input settings, for this to work and data log correctly? For example ; 0 volt = 0 percent / 5 volt = 100 percent.

The sensor is digital and there is no conversion. In 'Flex Fuel' set the input to 'Digital S300 AN0' and that's it. You don't need to enter anything for the analog input.

so in parameters, analog inputs, I leave analog0 as unused?
will it still show up in "display" window and display ethanol %?

I need the conversion rate so I can data log ethanol content. ive already set it to 'Digital S300 AN0' in flex fuel tab for compensation.
I think 0 volt = 0% & 5 volt = 100% is correct values for accurate data logging anyways. I 'll figure it out, thanks heaps

one last question that I'm unsure about is, am I able to use it as a digital ethanol content analyzer input to compensate for fuel \ignition but at the same time using it as an analog input to data log/view ethanol content percentage in the fuel???

Once you use the flex fuel sensor the analog input AN0 is disabled. The input is purely digital, and there is no voltage.
