ECU upgrade today is that two different series of car. The first is the Audi A4, the second picture is the Audi A6.

From this point of view, the difference between the appearance of the two vehicles is not large, with a silver car. Regarded as fate, coincidentally on the same day improvise modified computer software program.

This is basically what the technology does not exist to live, only to secure the ECU computer can be detached from the body. A6 using CMD Flash device operation, this mode of operation you do not need a computer by removing the ECU. But in any case the use of which device (determined by the ECU), tuning results are not going to change.
Mode of operation are similar, after reading the data to send data to the German DT, start tuning. The time was spent on the tuning data. Two car takes about three hours or so of data to return.
Data returned after dark, and quickly write data. After completing the test. Although it is a naturally aspirated car, but to enhance the effect is quite obvious. Lag significantly reduce a lot of sense, "to the oil to come," the feeling is very prominent.
