OBD II Tuning: How to Tune Your Car

Hello!

Immer wieder stolpere ich über Seiten, auf denen Tuning über die OBD II Schnittstelle angeboten und verkauft wird. Das kann ja nicht sein? Oder doch? Meines Wissens nach, befinden sich die Kennfelder und die dazugehörigen Einstellungen auf einem gebrannten Eprom (oder ähnlichem), also wie soll das gehen. Oder nutzen die die minimalen Verstellmöglichkeiten aus? Nur wie bringen die das dann zusammen, bei einem ACV eine Mehrleistung von 30 PS zu erreichen. Is Give me a riddle.

Has anyone here ever dealt with this topic before?

Regards, Peter.

The diagnosis, for example using VAG COM, is done via the K/L line. If you have a proper CAN-BUS interface, I can imagine that you might be able to modify the software in the control units.

This page (http://www.diagtronik.pl/forum) is a one-to-one copy of www.dieselschrauber.de.

Are there no copyrights involved??? Please take a look at this. Do the operators of "www.dieselschrauber.de" agree with this, or does this page even belong to them????

Hello Peter,
They are using the same forum software as Rainer.
In my opinion, there's nothing wrong with it.

Best regards, Rudi.

Hi,

What do you mean by 'rip-off' or 'copy'?
They're just running a forum that uses the same software (phpBB) provided by the same vendor. That's why the layout is so similar.

Hi everyone!

Okay, now I understand, and that's a good thing. I was just wondering if it was the right thing to do. I also didn't know that the surface for a forum could be resold multiple times; I wasn't aware of that. As I said, you never stop learning.

However, let's get back to the topic. I was able to view the page, but since my Polish is limited, I couldn't understand anything.
What about OBD tuning? Does it use the same adapter but different software, or a different adapter and software? Who performs it? What are the consequences for the engine? Who has extensive experience with it? How does the cost compare to traditional chip tuning, which involves working directly on the engine control unit and installing a new EEPROM? Are there any reputable companies that offer this service? So many questions...

Thank you very much, best regards.

Peter.

It doesn't work with the existing adapter, nor with VAG-COM.
You need specific hardware and software for this, which is extremely expensive.
But why don't you ask your tuner? He will certainly be able to explain the differences to you.
Tuning via OBD is quick and easy, but it's not always the best option.
Technically speaking, OBD tuning is the same as 'conventional' chip tuning.
