Sensor calibration
Sensor calibration table is used to define fuel ethanol content as a function of FlexFuel sensor
signal frequency. For GM/Continental sensors, ethanol content at 50Hz is 0% and 100% at 150Hz.

corresponding blending table (eg. VE Blend for VE table). The final value is calculated as follow::
Value = Tbl1[] * Blending% + Tbl2[] * (100% - Blending%)
If the frequency of the FlexFuel sensor is greater or equal Error
frequency, the sensor is not working correctly. In such cases the
check engine light can be enabled (Check engine) and the value from
the Fail safe Ethanol content parameter is used
