v1.0 - Bouletmarc
This program will sample a 50-150hz signal depending on ethanol
content, and output a 0-5V signal via DAC Converter.
This program will also sample a 0-100Duty signal depending on ethanol
temperature, and output a 0-5V signal via DAC Converter. (-40 to 80 celcius)
Connect 0-5V output to the desired OBD1 ECU Input (Honda), and tune
the "FLEX FUEL" parameter tab accordingly.
NOTE:
DOES NOT REQUIRE Lowpass filter to be used on output!
It use instead DAC Converter's (MCP4725)
