Check of the moment of ignition

In systems of ignition of Audi without the distributor it is impossible to regulate the ignition moment. At distributive ignition with the engine of 74 kW adjustment of ignition is checked by a workshop within technical inspection. For this purpose, first of all, the computer is interrogated. Then the control unit is given in a basic provision by ignition/injection. It also becomes by means of the device for computer reading.

Most to correct installation of ignition it is not meaningful, if in the beginning there was no считана information in the computer. As our being self-trained control units, they can carry out the corresponding adjustment of ignition if one signal of the sensor, for example, dropped out. Before something will be changed in ignition installation, it is necessary to be convinced in the beginning that any defect in system did not distort ignition installation.

The same treats so-called main installation by means of the device for V.A.G 1551 computer reading. While the control unit is not given in a condition of the main installation, correct adjustment cannot be carried out. Therefore the most suitable partner in this work is Audi workshop. The workshop makes check on the following parameters: control size: 0–12 °; adjusting size 0±3 °.
