The ECU has several functions that “Learn” what the required settings are based on sensor signals. The fuel learns how much correction is needed to achieve the target AFR, at steady state.

Cal No-Save 196 = Sometimes, the changes made to the calibration DON’T want to be saved – to prevent saving at Key Off, set this value to 196.
TPS Zero Count = This is FYI only – it’s not ‘adjustable’ in the calibration. It shows the learned value of the TPS when it’s fully closed.
Fault Clear 1 = Set this to 1 in order to clear any recorded faults. This can be used if a repair has been made, or perhaps if a false fault has been detected, or fault diagnostics are being done to solve a problem.
Reset All Learn = Set this to 1 to return all learned values to the default values. This clears the fuel learning, idle air learning, and closed throttle position learned value.
Reset Fuel Learn = Set this to 1 to clear the fuel learning.
Reset IAC Learn = Set this to 1 to clear the IAC learning.
Reset TPS Learn = Set this to 1 to clear the TPS closed position learning.
