- **Sensor frequency -** The minimum and maximum frequency of the sensor that represent 0% and 100% ethanol respectively. For standard GM/Continental flex sensors, these values are 50 and 150
- **Fuel multiplier% -** This is the additional fuel that should be added as ethanol content increases. The Low value on the left represents the adjustment to the fuel map at 0% ethanol and will typically be 100% if the base tune was performed with E0 fuel. If the base tune was made with E10 or E15 however, this value can be adjusted below 100%. The high value represents the fuel multiplier at 100% ethanol (E100) and the default value of 163% is based on the theoretical difference in energy density between E0 and E100. Tuning of this value may be required
