Setting timing with Motronic
- Connect BMW MoDiTeC to diagnosis plug.
- Call up the TOOLBOX menu on the diagnostic unit and select the HALL TRANSMITTER SETTING item.
- Crank the engine to bring the piston to the ignition firing point.
Setting:
- Ignition timing — 6° before TDC = 0.24 mm (0.010 in) before TDC
- Follow the MoDiTeC instructions.
- Slacken the screws securing the magnetic gate (2, 3) and turn it to the left or right until the BMW MoDiTeC displays the correct ignition firing point.
Adjusting ignition timing:
- Turned counter-clockwise — retard ignition
- Turned clockwise — advance ignition
- Retighten magnetic gate (2, 3).
- Check that ignition timing is correct.
- Turn the engine in its normal direction of rotation. With the piston at 0.24 mm (0.010 in) before TDC, the BMW MoDiTeC must display the correct ignition firing point.
- Installation is the reverse of the removal procedure.
Setting timing without Motronic
- Open the electronic equipment box.
- Connect the BMW MoDiTeC to plug connector (4) for the Hall-effect transmitter.
- Perform the HALL TRANSMITTER SETTING routine with the MoDiTeC.
