Flex Fuel only reading while cranking
Hello,
I recently wired in my flex fuel sensor, digital-to-analog adapter, and Science of Speed accessory power panel, and enabled it all correctly in Flashpro, but it is only detecting ethanol percentage when cranking, and at any other time it just reads 0%. When cranking its currently reading about 45% ethanol but as soon as it is started up it no longer reads and subsequently dies at idle from not enough fuel compensation, which I am expecting the ethanol fuel compensation table to account for. Any insight would be great.
Side note: sensor is grounded to subframe, sensor receives power from accessory panel, sends signal to digital-analog converter, which then sends signal to ECT2 pin. Digital-analog converter also receives power from accessory panel, and is grounded to ECU ground. It is the KTuner Flex Fuel converter and the effective voltages set in Flashpro are 0.5V-4.5V as per Ktuner and SOS.
