Check of the moment of ignition

The ignition moment, actually, in elektronno operated systems of ignition of Audi 80 cannot get off. But nevertheless the workshop within the test of a mode of idling and dough for toxicity of the fulfilled gases supervises including ignition installation. For this purpose it is necessary to interrogate memory of the store of malfunctions first of all. Then the control unit of system of ignition should be led to the main installation. It also becomes the device for reading of memory of the store of malfunctions.

It is no point to correct independently ignition installation if before it the store of malfunctions was not interrogated. As our control units are being self-trained, they can carry out necessary specification of installation of ignition, for example, if there is no signal of one of sensors. Before something to change in ignition installation, it is necessary to be sure that installation of ignition was not spoiled by any failure in system.
The aforesaid is applicable to so-called main adjustment by the device of reading of memory of the store of malfunctions of V.A.G. 1551. Until the control unit was not given to the main installation, it is impossible to carry out the correct adjustments. For this reason it is necessary to address in Audi workshop. There will carry out control on the indicators given below.

Adjusting data

The table shows one test and one established indicators of adjustment of ignition that it is necessary to understand as follows: at express control are guided by the bigger admission of a test indicator. If adjustment in any case is required, it should be made thoroughly, whenever possible is approximate to the established indicator.

 Help: the switch of a signal of idling and the sensor of detonation combustion influence the moment of ignition of the car with the corresponding equipment. The faulty sensor of detonation combustion can be distinguished on that the ignition moment after short-term pressing a pedal of an accelerator is late at least on 10 °.
