Auto-calibration
Auto-calibration is possible once the reducer temperature has reached the level of 60 °C. Start
the engine and wait until the lambda probe starts working before proceeding with the auto-
calibration procedure. Appropriate LTFT and STFT corrections are important when running on
petrol. Usually correction values should oscillate around 0%. When performing auto-calibration,
the engine should work at idle run. Do not rev up the engine, AC and the lights should be turned
off. Do not move the steering wheel, as this might result in an incorrect course of the calibration
procedure. Once
Auto-calibration
window has been selected and
Start
button clicked, the
Choose engine code
window will be displayed.
