Map, glow plug EDC 16C39

[MultiBravo]

Hello guys!!!
Happy new Year to All!!!

On edc16c39 who knows where to find the map that adjusts the duration of the light of the glow plugs according to the temperature of the engine?
I checked the wiring diagram and actually ? the engine control unit to the controlled ecu, glow plugs and light on the framework..
Everything stems from the fact that I would like to increase the duration of the light for 1 second at mild temperatures why? if you look on the second ip? the
engine part very well (when the light ? off the glow plugs continue even for a few minutes to be fed).
I assume there is a map that regulate the duration of the signal that regulates the duration of the post-heating.

No map... the ecu that runs the glow plugs ? for her facts...the ecu the engine by only the on/off command based on the engine temperature.

[MultiBravo]

the on/off control ? given from the engine control unit and I agree..
Then the light on the dashboard ? controlled by the control unit glow plugs? who says to the ecu plugs on the engine temperature?
someone has a wiring diagram of the detailed connections?

[blackwolf76]

The control unit glow plugs receives the on/off signal from the engine control unit which, in turn, evaluates the temperature of the motor based on the signal it receives from the temperature sensor placed on the thermostatic valve. The light ? unit-controlled glow plugs, I will continue to heat even after that ? turned off the light. If you wait more than the light you get the same effect.

[MultiBravo]

oh well, I know, however, that continue to warm up, it was only to make people wait more? those not in the know..
? adjustable via trimmer/potentiometer the time?

[blackwolf76]

I think not... the ecu plugs also evaluates the absorption, given that if some of them ? burnt signals via light in the dashboard, so I can imagine what is pi? complex than a simple trimmer.

Instead ? the engine control unit to control the light in the picture..
I attach an extract from the manual found on the net:

"The engine control unit M10 receives the signals from the various sensors, while maintaining cos? under control all the operating parameters of the engine.

The sensor turns K46 provides, through a signal in the frequency sent to the pin 100 of the control unit M10 , information about the speed of the motor. It receives from the pin 99 of the control unit a signal of mass. Both signals are of low intensity? and therefore you are? are properly shielded to pin 101.

The phase sensor K47 ? powered by pin 102 of the M10 . It receives a reference ground from the pin 104 of the control unit M10, and via a signal frequency corresponding to the phase of the pin 103.

The engine temperature sensor K36 , receives a ground signal from the pin 85 of the control unit M10 , and provides a signal proportional to the temperature of the liquid of the motor to the pin 84.

The flow meter air K41 receives the power supply from the line of the fuse F11 B1 , from the pin 88 of the M10 receives a reference voltage. It is fed by the ecu from pin 97 of the M10 , and sends it to the pin 89 a signal proportional to the flow rate of air. Within K41 ? also placed an air temperature sensor that sends a signal to the air temperature to the pin 86 of the M10 .

The accelerator pedal K55 ? equipped with two potentiometers integrated (one main and one safety). The first receives power supply and ground, respectively, by the pins 78 and 76 of the M10 and sends the corresponding signal to the pin 77. The second receive power and ground, respectively, by pin 81 de 79 of M10 and sends the signal to the pin 80.

The temperature sensor fuel K81 detects the temperature of the fuel input. It receives a reference mass from the pin 83 of M10 and sends it to the pin 82 of the same the temperature signal fuel.

The sensor turbocharger K82 detects the pressure of the turbocharger. It ? powered by pin 93 of M10 and receives from the pin 95 with a reference mass. The signal is sent to the pin 94 of the control unit.

The pressure sensor fuel K83 has the task of providing the ecu with a feedback signal to adjust the pressure and the duration of the injection. It receives the power and ground respectively by pins 90 and 92 of the M10 ; it then sends the signal pressure to the pin 91.The pressure regulator fuel N77 has the task of keeping constant the value of the fuel pressure in the accumulator. The two control signals come from the pin 108 and 109 of the control unit M10 .

The solenoid valve EGR L30 controls the recirculation of the exhaust gas; ? powered from the line of the fuse F11 B1 , and is controlled by a signal of the pin 16 of the M10 .

The solenoid valve control the variable geometry turbine L36 regulates the operation of the turbine as a function of the load of the engine. powered from the line of the fuse F11 B1 , and is controlled by a signal from pin 17 of the M10 .

The solenoid valve on the throttle body L62 partial and closes the butterfly, for example, to shutdown of the engine; ? powered from the line of the fuse F11 B1 , and is controlled by a signal from the pin 15 of the M10 .

The pin 59 M10 receives the signal from the stop light switch I30, powered "key" (INT) from the fuse F37 of the control unit B2 .

The pin 61 of the M10 receives the signal from the clutch switch I31 .

The injectors N70 receive the power to consent to the opening of the pins 117 (cylinders 1 and 2) and 118 (cylinders 3 and 4) of M10 .

The engine control unit sends the command to the injectors N70 by the pin 119, 120, 121 and 114, respectively, to the cylinders 1, 2, 3, and 4.

The control unit M10 receives the pin 98 -- the signal of the sensor minimum engine oil pressure K30 .

The sensor of the presence of water in the diesel filter on a K31 ; ? powered from the line of the fuse F11 B1 , and sends the corresponding signal to the pin 105 of the M10 .

The control unit M10 then connects via the CAN network to the Body Computer M1 and to the other nodes of the network: through this connection, it sends information about:

self-diagnosis of the system, that can? be used by connecting to the connector G M1
engine water temperature, which is sent to the instrument panel E50, which manages the indicator and the indicator relating to it;
the engine rpm, which is sent to the tachometer in the instrument panel E50 ;
minimum engine oil pressure, which is sent to the instrument panel E50, which manages the light;
glow plug, which is sent to the instrument panel E50, which manages the light;
the presence of water in the diesel filter, which is sent to the instrument panel E50, which manages the indication on the display.
Instead receives, always via CAN signal tachometric"

Here is the map of the candellette. I had an original alpha with startup problems. But also by changing the diesel fuel in the boot and the ignition candellette , new battery, does not always start on the first lap.

I think the main problem is always the system's infernal DPF....

I don't understand why I cut the images.... mah , placed

Grandeee!!! Great ideas..

You have changed from 1CEEB8, then it would be the "pre-glow time in phase 1" of the image with the final 23?
And the "pre-glow time (2)" that you have highlighted what you need?
I thought it was a simple time vs temperature liquid cooling.. but how many maps..

I have seen that you have increased the map well gas, almost to the ****llo of the jtd that after 60?C travel constant at the value 2000, to 40?C 2700..
With the increase of time the glow plugs and diesel have you noticed an improvement? part with half a turn of the key?
