OBD
11 Is a bit of software that connects to your VAG car via a specific OBD2
Dongle that allows you subject to setup to make changes to the cars setup, what and how stuff works, record live data and
has various Gauges so you can check on specific items whilst the car is
working. For
the purpose of this web site I will only show and
discuss changes to my 2014 Cupra 280. Any coding shown that you use will be
at your own risk. |
Information:
There are currently two
separate OBD2 dongles available for OBD11 one is the Legacy one that only
supports Android phones, the second will support both Android and IOS and will
be expanded to support other makes of cars (first one selected will be BMW).
For a fuller list you should
check out this post
on the OBD11 Forum where you will find a good list of all the changes that
are possible to code.
Within the application you
have the following functions (again we are just talking about the 280 here) for
the following control units:
01 – Engine Control Module 1
– Live Data here
02 – Transmission Control
Module – for the dsg not sure about manual gearbox –
Live Data here
03 – Brakes 1 – Live Data here
08 – Air Conditioning – Live
Data here
09 – Central Electrics –
otherwise called BCM in VCDS world – Live Data here
13 – Adaptive Cruise Control
– Live Data here
14 – Wheel Dampening
Electronics – Live Data here
15 – Airbag – Live Data here
16 – Steering Column
Electronics – Live Data here
17 – Dash
Board – Live data here
19 – Gateway – Live data here
32 – Lock Electronics –
otherwise known as the front dif – Live Data here
42 – Door Electronics Driver
Side – Live Data here
44 – Steering Assistance –
Live Data here
52 – Door Electronics
Passenger Side – Live Data here
55 – Headlight Regulation –
Live Data here
5F – Information Control Unit
1 – Live Data here
76 – Parking Assistance –
Live Data here
A5 – Front Sensors Driver
Assistance System – Live Data here
A9 – Actuator For Structure Borne Sound – Just turn it off. – Live Data here
1/ Ability to scan the car –
Running a scan this will identify any issues that the control systems have,
some may be shown on your cars screen but many will
not.
2/ Long coding – for each
control unit you have switches that are setup in Long
coding and also Adaptions, the screen will show you for each byte a list of the
bits and if they are ticked or not. The data is held in hexadecimal format so
you can just change the hex code or tick and save the individual bits.
3/ Adaptions – As above but
these switches allow you to turn stuff on or off or change the way it works.
4/ Live data – this can be
used in one of two ways, firstly as a simple screen display so that for example
you can see the Engine Revs, Car Speed and Intake air temp all together, Secondly you can use the Chart function which allows you to
record this data and export it as a .CSV File for further analysis.
Thanks to DV52 once again for this following explanation
(which made perfect sense to me):
All modern cars can be considered to be nothing more
than a number of control systems connected to an engine and a set of wheels
(yes this is a gross simplification, I agree!). Most control systems in a car
are what's called "closed-loop systems". And ALL these control
systems operate the same- they all perform a very basic task: They have an
internal process that produces an output signal based on feedback and an input
signal(s) - often feedback comes from a sensor/transducer of some sort.
DV52 Picture (thanks)
In all modules that operate control systems (i.e
control modules) and regardless of the vehicle, there are really 3 x aspects
that are able to be modified:
1/ Firmware
2/ Adaptation channels
3/ long coding
Firmware is like the heart-beat of the module's life-force: this is the
internal software that operates the procedures for controlling some aspect(s)
of the car. Firmware determines how the module will operate and the module's
firmware relies on "inputs" to tell it about the external world: how
the car is physically configured and what "parameters" the module is
to use in certain circumstances (like how to turn ON/OFF each of the car's 35 x
exterior lights). Some diagnostic cables like VCP can change firmware, but not
OBD11, or VCDS.
The "inputs" that the firmware relies upon are "2
(Adaption)" and "3 (Long coding)" above. Now, I'm not sure what particular distinction VW officially uses between
"adaptation channels" and "long coding", but my guess from
observations is as follows:
Long coding are the software switches that tell the firmware what physical
sensors/physical switches are installed in the car. For example, when a
light-sensor is installed, a long coding Byte/Bit has to
be set to tell the control module firmware to start measuring the sensor output
and to do stuff to control the car's lighting.
Adaptation channels are generally different sorts of "inputs" that
tell the module how-to-behave. For example, Leuchte
programming is done by changing adaptation channels - these channels tell the
module what function to allocate to each lamp and what level of illumination to
give to that lamp.
Basic Settings
thanks again to DV52 for definition
Basic settings are just another form of "input" to the closed-loop
system. Speaking generally again, the more sophisticated sensors on a car need a initial set of parameters to to establish a reference point. The module's firmware uses
this data as a "starting-point" for the feedback process in later
operation.
For example, changing some adaptation channel values in the BCM will lose the
level-horizon settings for the range-control motors on the headlights. The
Basic settings procedure (for the modules @ address hex55) re-establishes the
sensor's setting for level-ground. When these modules are taken from stock at
the VW factory - each car goes through this basic setting procedure to
establish zero degree tilt - as a reference setting.
Once the module knows where zero-tilt is, it can accurately measure +ve/-ve angles.
and Readiness
thanks again to DV2 for definition
Readiness is a group of "parameters" (usually 8 x binary Bits) in the
engine module which indicate the health of the car's emission systems. A state
of 0 means "fail" and 1 means
"passed". Whenever you bulk clear DTCs, ALL 8 x bits are set to the
"fail" state - if your car doesn't have all 8 x emission test
capabilities, those Bits will automatically be reset to 1.
Live Data
As the name implies these are just labels that allow you to watch and record
(via charts and online screen) the live data where it is supported on your car

Warnings
Please do not run factory reset unless you
fully understand the damage and effort to put it right after
Please make sure you run a backup before any
changes
