Are you sure it is pulling timing? Many cars with the A6 will dive into the part of the timing table that many people do not change. For example at 1600 RPM and .64 grams/cyl of air there is only 9 degrees.

Try to modify the table at lower RPM levels and higher load levels and check it again. If you send me a scan I can tell you for sure. I can read any scan you send me, I don't know what software you are using.

Aside from logging total advance... log all of the spark adders/retards to see what sources are pulling timing out.

What conditions are you seeing the timing get pulled out?... A log would help.

Got it. The car is doing as I suspected. Under 1700 RPM you are in a part of the timing table that is very low.

Actually you are at .64 gm/cyl at only 800 RPM. Not very much timing down there!

Bring those numbers up, but dont get crazy. Keep them in the high single digits to start.

Good luck and happy tuning!

Also, you have zero upshift torque management. I would just reduce it by 50% or so. What intake is on the car? You are pulling a 12 Kpa depression in the manifold, thats huge.

Holy crap... and I thought 3kPa was bad!

Thanks Kirk!
I will add timing down in those areas! It stll has the stock air filter system.
Thanks again!

Whenever I tune somebody's automatic (usually in C6 Corvettes) that's one of the first things I work on as it can make a huge difference to how the car takes off. In my car I only see about a 2-3 drop when I launch the car at the track.

I agree with Kirk though in that you have to add more timing in small increments until you're happy with the results.
