I understand that the ECU adapts software to your driving style. I'm about to have a new cpu placed. Obviously, it's winter and my driving style will not be too aggressive with this weather (snow). Will this adversely affect how the module adapts the to my driving? Any recommendations. I assume the car will re-learn how I drive...although I understand that the car has two ecm's so this may be a non issue....looking for any insight Thanks in advance.

If your worried about what the ECU learns over the winter you can reset it in the spring using a VAG

where can I find the coding for this.... interested in doing it to mine

to reset the ECU(s), you have to go into Engine 1 and Engine 2 and hit 'clear codes' in each, IIRC.

What happens if you don't reset ECU ever?

The ECU is always dynamically adjusting air fuel mixture in real time and timing over a longer period of time. It doesn't "learn" your driving style. It adjusts in real time to the ambient conditions by controlling A/F ratio and timing, by looking at the broadband O2 sensors and listening to the knock sensors.

Throttle position is only one of many parameters that input into the ECU. If you've been driving around like a ***** for a while, the ECU may not give you full output the first time you decide to nail it, but after that, it will readjust the actuator outputs accordingly. More than likely, the ECU processes so fast that in the time it takes you to depress the accelerator from 50% to 100%, the ECU has already adapted to the new throttle position. So you can say it "learns", but it also "unlearns" ad "relearns" just as quickly.

ECU inputs/outputs and adjustments happen on a millisecond time scale. Don't worry about it. You can reset your ECU with a VAG or by disconnecting your battery.

Evidently that's how they all work these days. Anyway.. got "the thing" back and very happy, AND no charge for the keys to be programmed!! Actual honesty!!! He said, "they were in there anyway--&lt;in effect&gt;-- so please now just respond to the survey... "very satisfied" is a C+ I have to be MAXIMALLY SATISFIED!! I am for now...

Plowed through 10" on Thursday with no trouble whatsoever. People were getting stuck and stranded and I was actually having fun! This car is unstoppable!!
