Flex fuel question
Posted: Thu Mar 28, 2024 7:45 pm
Hi, im struggling to get my Ktuner software recognize ethanol content. Car is European domestic market MY07 and im using Ktuner Flash V2. Also im using Continental GM #13507129 and Ktuner Flex Fuel converter and im reading 0,8 volts output from converter when im using 98 RON (European 98 octane with 5% added ethanol).
As the converter outputs are: 0% at 0,5volts and 100% 4,5volts => 0,8 volts would be like 7% ethanol content. I have connected converter output to E1 (ECT2) pin, enabled Flexfuel from advanced parametres and flashed ECU but Ktuner software doesnt read anything from sensor ECT2 or Ethanol content. Is there something im missing?
