1) The ignition timing is also used for idle speed stabilization. In extreme cases the timing can briefly vary by ±10° from specification.2) In case of complaint, on-off ratio must be measured at idle speed and at 2500 rpm with purge line to engine disconnected and plugged.4) Base setting idle, 0.0 kg/h (Bosch) or 0.0% (VDO), mixture tendency rich, < 0.0 kg/h or 0.0%, mixture tendency lean > 0.0 kg/h or 0.0%.5) Base setting part load = 1.0, mixture tendency rich <1.0 mixture tendency lean > 1.0.10) Oscillates around 300mV after 2 minutes at idle.12) Time Guide operation no. and/or SMS job no.13) HHT display ON if self adaptation is required.
