CAMARO6 - View Single Post - Ethanol with / without a Flex Fuel sensor

1.) If I simply add a certain % amount of Ethanol to the tank, will the ECM adjust timing automatically, or is a calibration necessary?

2.) Doing the same, but installing a Flex Fuel sensor.
Again, same question- Will the ECM compensate / adjust, or is a calibration of the maps necessary?
