The ignition timing for the VAZ 2108, 2109 and 21099 engines is different but not more than 3 degrees. The advance (up to 12-14 degrees) may only be possible when trying to adjust the defored engine (calculated on the 80th gasoline) to high-octane fuel (95-98).
WAZ for engines of VAZ engines is displayed on the scale and flywheel label through the clutch in the clutch.

The verification of the OO is done in two ways: when moving at a speed of 60 km/h on a direct gas transmission, a rapid detonation has to occur. If the detonation lasts more than 3 seconds, the advance angle must be reduced and, if not, increase the speed of the forward movement at 80 km/h to the engine speed, the engine must be heard several claps into the silencer

- when moving on a straight gear at 80 km/h, switch to engine braking-the engine must be heard a few claps into the silencer
