VAG COMM???

[[email protected]]

So I am a little confused. Is VAG COMM only for diagnostics, or does it make our ECU's fully programmable? Can you tune the car with it? (I searched the Ross-Tech website for a while and couldn't find any definitive answers)

If so, do companies or AZ'ers have base maps to use with it? Are there people who can help tune in the car?

Thanks everyone. This should help all folks interested in getting the VAG COMM and who might be a little confused.

Vag-Com can not be used to tune our cars. You can use it to check codes, record logs, and change settings like using your FOB to roll your windows up or down.

Vag comm is a software package that will talk to the OBD2 computer. It provides an interface for the end user to access diagnostic data, create logs, and change certain values. Basically, it is an interpreter of the machine language inside the ECU, in a format that is organized in sections. Sort of like a Hex editor, but Vag Comm goes a little further by grouping the machine language values with an interface. Normally, the VAG (volkswagen Audi Group) data in the ECU is inaccessible and is encoded, so the Vag Comm decodes the raw machine data for you.

When changing the values, as in the convenience setting that the other poster has talked about, you need to enter the correct replacement value that corresponds to the proper numerical values that will turn on or turn off certain switches.

So yes, you can get the engine codes from the Vag Comm and you can also change other factors/values.

The software interfaces with the hardware via OBD2 to USB or RS232 serial.

Thanks guys, I really appreciate it. Is there an interface we can use to fully tune our cars?

My friend has an RSX-S and just got KPRO, a fully programmable ECU package. Not only did he get the new ecu, with USB plug, the new wiring harness with adapter, but he also paid for base maps and future tuning through data logs. What he paid for allows him to email in his data logs (80 allowed) and Hondata will send him new maps based on his data log performance.

We just did some logs and it kicks ass. Kinda makes me want to go with the K20 motors because they are so f-in badass! Is there any similar system for our cars? If not, some of us should get together and make one...LOL! (I'm sure the market would be HUGE and I can put together a stellar bplan)
