Голф 3 -1.9 ТДИ 90кс. - Какво може да се оптимизира с ВАГ

[bate]

Здравейте! Интересува ме какво и точно как може да се оптимизира с ВАГ КОМ. За да се пипнат различни видове настройки трябва да се въведат различни кодове до колкото разбирам-може да ги споделим в полза на всички. Надявам се да не дублирам някоя тема. Мисля, че ще е от полза на всички които не са толкова наясно какви са точните възможности на ВАГ КОМ. Имам приятел който ми бутна стойностите на милиграмите гориво на 2.6 /не знам как точно да се изразя и най-вероятно се изразявам неправилно/ и ми обясни, че така било по добре и колата ще стане малко по пъргава. Да стана по пъргава, но аз не разбрах какви са тези стойности и какво точно се случва/ по икономична ли стана или по пъргава за сметка на горивото/.
Видях, че може и други стойности да бъдат променени, но разбира се ако ги променя не знам какво правя всъщност. За това се надявам колегите които са в час да пишат.

Виждам, че сте доста изчерпателни, но все пак не знаех, че за адаптация трябва в режим на диагностика, избирате [01 - Engine], след това [Login - 11], въвеждате код 12233 и след това [Do It!].
А някой може ли да ми обясни на кой канал какво и как може да се подобри и да се промени изобщо?

[bate]

та значи става въпрос за промяна на количеството гориво което се впръсква с помоща на ВАГ КОМ
значи закачате се към колата избирате [01 - Engine]
после отивате на [Login - 11] и там пишете код 12233 и след тва [Do It!]
след това отивате на [Adaptation - 10] от 1ви канал се променя горивото ако не е пипано числото трябва да е 32768
колкото сваляте цифрата надолу толкова повече гориво се впръсква максималната граница е 9mg/h а нормално трябва да е около 3-4 mg/h
на 2ри канал се повишават или намаляват обортите на празен ход там чилата са същите,принципа също
на 3ти канал се намалява или увеличава стойността на ЕГР клапана за да баде на мин. числото трябва да е 33768
на 18ти канал се променя ограничителя на скоростта там се въвежда просто желаната скорост
а ако искате да нулирате всички стойности и да им дадете заводски настройки просто избирате канал 00 и давате "SAVE"

[bate]

Така че, за да се увеличи времето подгряване, просто трябва да влезете в двигателя модул и направи адаптацията към изменението в канал 12 .

Това са стъпките:

1 ) Включете запалването
2 ) Отидете на двигателя контролер
3 ) Влезте с 12233 като код
4 ) Кликнете върху адаптация и отидете на канал 12 .
5 ) Промяна на стойността от 32 768 (зададени фабрично ), доа някъде около 32 700
6 ) тест Click, след това запишете новата стойност.
7) Затворете контролер
8 ) Изключете запалването и се върне отново.
9 ) Отидете на двигателя контролер и влезте отново.
10 ) Отидете на адаптация блок 12 и ще видите промяна във втория прозорец. Тази стойност е сумата, от време в секунди , че подгряващи свещи ще бъдат активни .

[bate]

На канал 30 в Адаптация мисля че се настройва на колко литра да светне резервата на горивото ?!

[bate]

Channel 05 - Незнам, но ми се струва, че е центровка за палене
Промяната на стойностите влияе на паленето, пробвайте как ще пали най-добре ?!

[Zinoto]

Тия адаптации се ползват САМО ако има някакъв проблем и е правено нещо по хардуера. Изключение е 3 - ти канал с увеличаване на стойността се намалява действието на ЕГР. 5 - ти канал ти е стартово гориво, но няма смисъл да се мъчиш да постигнеш нещо от там, скоро беше дискутирано в една тема. В първи канал колкото повече намаляваш стойността и числото на мг. расте, толкова всъщност намаляваш горивото при натиснат педал на газта.

Здравейте,ето какво открих по темата.

AN EXPLANATION OF ADAPTATION CHANNELS
This will be an explanation of the adaptation channels in VW/Audi ECUs,
how they can be modified, and what effect they have on engine operating
parameters.

Adaptation channels allow VW/Audi dealers to make minor tweaks to engine
operating parameters (e.g. engine idle speed adjustment). These
settings can be modified using the dealer's diagnostic equipment or
VAG-COM.

These settings are stored in a serial eeprom which means the settings
will not be lost if the ECU loses power. This is the same eeprom that
stores data that can change from time to time like diagnostic trouble
codes. This serial eeprom is different from the flash memory chip that
stores the main engine control program, and therefore changes made to
adaptation channels will not affect code checksums.


As an example, let us take a VR6 owner who is happy with the performance
of his engine but would like to have his speed limiter raised. There is
an adaptation channel that can be used to raise or lower the speed
limiter setting, and if there were a way to change this adaptation
channel then there would be no need for this owner to even buy a chip.
He would be able to continue running with bone stock ECU programming
with no worries about a dealership detecting a chip (since there is no
chip), and if he were particularly worried he would simply restore the
default factory setting before bringing the car in for service.


So, he connects to his ECU with VAG-COM, goes to adaptation channel 7,
and tries raising the speed limiter. But it doesn't work: the commands
that request the setting of new adaptation channel values have built in
limit checks and reject the new values. In this particular case, the
speed limiter related adaptation channel is effectively disabled since
the stock ECU programming limits the control range so that the only
valid value is zero (i.e. no change).


So the issue boils down to this: is it possible to change these adaptation
channels in such a manner that the original factory limits are bypassed?
There are two possible approaches. First, one can make a chip with the
preset adaptation channel limits extended to allow a larger adjustment
range. Second, one can bypass the VAG adaptation channel routines and
directly place the new adaptation channel settings into the ECU.

Changing the preset adaptation channel limits in a chip is the only
option for VAG group diesel ECUs, Magneti Marelli ECUs, and older Bosch
ECUs. These codes check the adaptation channel limits after the values
have been read out of the serial eeprom. Motronic 7 ECUs do not do this
check which opens up the second method.


Directly transferring the new adaptation channel values into the ECU
works by finding the RAM memory location where the ECU stores the
adaptation channel data and directly writing the changes to those RAM
memory locations. When the ignition key is turned off the ECU enters a
housekeeping mode where among other tasks the modified adaptation
channel data is written into the serial eeprom. This roundabout method
is required because memory writes directly to the serial eeprom are
blocked.

Interestingly, this method will not work using the VAG mode protocol.
Write access is allowed to any ECU RAM location except those locations
that store the serial eeprom data. Someone at Bosch clearly knew about
this vulnerability and took measures to close this loophole. But for
some reason this loophole was left in the KWP2000 routines.

Each ECU code stores this adaptation channel data in different RAM
locations. To make this method work with any ECU one runs through the
following steps: 1) Establish communications with the ECU using KWP2000
mode; 2) Read data directly from serial eeprom (since read access is
allowed); 3) Search for this data in the ECU's RAM; 4) Write the new
adaptation channel settings to the RAM location; 5) Cycle ignition key
to have ECU transfer the new settings into the serial eeprom.

The KWP2000 protocol is not as reliable as the VAG protocol. Some cars
will have communications problems which often can be worked around by
pulling the instrument cluster fuse (make sure VAG-COM will be able to
clear you air bag DTC light before doing this!!!).


Using the KWP2000 protocol gives one the ability to change settings in
any VAG Motronic 7 ECU regardless of whether the ECU is stock or
chipped.

[Adaptation Channel Functions]

This lists all Bosch Motronic 7 adaptation channels with a typical
factory VAG control range and the maximum possible control range
if one were to directly write changes to the serial eeprom.

Note that Bosch Motronic 7 codes have differences in what adaptation
channels are actually implemented.


Channel 1: Additive Engine Idle Speed Offset

This channel allows one to adjust the engine idle speed in steps of 10
rev/min.

Typical VAG control range : -50 rev/min to +50 rev/min
Maximum possible control range : -1280 rev/min to +1270 rev/min

Channel 2: Tweak on fuel enrichment based on increasing loads (i.e. accel pump)

This channel adjusts a fuel enrichment term that is proportional to load
rate of change and that acts to enrich full when the engine load is
increasing. This is equivalent to an accelerator pump function

Typical VAG control range : 100% to 110%
Maximum possible control range : 0% to 200%

Channel 3: Tweak on fuel enrichment based on decreasing loads

This is very similar in function to channel 2 but adjusts a term
that works to decrease fuel when engine load is decreasing.

Typical VAG control range : 90% to 100%
Maximum possible control range : 0% to 200%

Channel 4: Tweak on Startup Fuel Enrichment

This adjusts the startup fuel enrichment term.

Typical VAG control range : 100% to 110%
Maximum possible control range : 0% to 200%

Channel 5: Tweak on Warmup Fuel Enrichment

This adjusts the warmup fuel enrichment term.

Typical VAG control range : 90% to 100%
Maximum possible control range : 0% to 200%

Channel 6: Lambda Regulation

This tweaks a lambda regulation system's narrowband oxygen sensor
cycle time in steps of 10 milliseconds.

Typical VAG control range : -100 ms to +100 ms
Maximum possible control range : -1280 ms to + 1270 ms

Channel 7: Additive Offset On Speed Limiter

This is allows one to adjust the speed limiter in steps of 1 kmh.

Typical VAG control range : 0 kmh (no adjustment allowed)
Maximum possible control range : -128 kmh to + 127 kmh

Channel 8: Secondary Fuel Tweak

This adjusts the main fuel term.

Typical VAG control range : 100% to 110%
Maximum possible control range : 0% to 200%


Channel 9: Additive offset on ignition timing angle

Allows one to shift the ignition timing angle up or down in steps of
0.75 degrees.

Typical VAG control range : No adjustment allowed
Maximum possible control range : -96 Degrees to +95.25 Degrees

Channel 10: Primary Fuel Tweak

This adjust the main fuel term.

Typical VAG control range : No adjustment allowed
Maximum possible control range : -25% to +24.8%

Channel 11: Unused

Typical VAG control range : No adjustment allowed
Maximum possible control range : -128 to +127

Channel 12: Specified Engine Load Scaling Factor (Turbocharged cars only)

This factor allows one to scale the specified engine load. The default
value comes set at the maximum value, so specified engine loads can only
be reduced with this adaptation channel.

Typical VAG control range : only 100% allowed (no adjustment allowed)
Maximum possible control range : 0% to 100%

Channel 13: Control Bits

These control bits affect engine idle control.

Typical VAG control range : limited to 2 control bits
Maximum possible control range : 8 different control bits can be set
or cleared

Channel 14: Additive Offset To Idle Torque

This channel allows one to raise the minimum torque maintained at idle.

Typical VAG control range : 0 to 31 (arbitrary units)
Maximum possible control range : 0 to 255 (arbitrary units)

[Checking and resetting adaptation channel settings using VAG-COM]


Adaptation channel settings can be checked, tweaked according to the
preset factory limits, and reset to the factory defaults using VAG-COM.

Connect to the car's ECU by opening the "Select Control Module" screen
from the start screen, then select the "01-Engine" Module. Once
you are connected to your ECU open the "Adaptation-10" screen.

You can cycle through each adaptation channel. For each channel you will have the currently stored adaptation value read in; you can then enter a new test value and press the "Test" button to see whether the new value is acceptable to the ECU; then you can hit the “Save” button to store the new adaptation value.

If you would like to restore all adaptation channel factory defaults you can save a test value of “000” to channel zero.

The following shows the factory default adaptation channel settings:

Channel Factory
# Default
------- -------
1 128
2 128
3 128
4 128
5 128

а може ли да споделиш на кой канал се прекодира от ръчни на автоматични и пак ли става от меню "01-engine"?

Ето малко инфо за смяна от ръчка на автомат и обратно.

Guys!!

You had a solution back there...

Not really a solution but a workaround, and no-one tried it..

Recode the ecu for auto Gbox.

connect to the engine block, go to recode, and change the value from 2 to 1, or the other way around.. if it's 1, change to 2, if it's 2, change to 1..


Tha car will start instantly, but a low band pass filter in the accelerator get's disabled. so if you move the acel fast, the car will jerk a little..

the common answer here in europe, is that the starter was badly designed, and when hot (the starter) it'll not acchieve the 250rpm's.

when you change it to auto gearbox, the ecu starts injecting at 50rpm's, so it'll start right away..

so.. please, try it..
