Ethanol sensor connection.
MaxxECU usage
Start by activating the Ethanol sensor on wired digital input (DINx).
Check real time value for connected ethanol sensor in the RealTime Data tab in MTune.
If 85% and 0.0degree C = no sensor connected. If temperature is 125 degree C, the polarity is wrong, change active level high/low.
Note: If the system detects an ethanol sensor error/contaminated fuel, it will keep the existing ethanol content % and use E85 fuel stoich AFR (9.7)
