Ls1 edit and A4 Can someone guide me on how to tune the A4 with Ls1 edit? I have my car running great thanks to a recent dyno tune session and ls1 edit (thanks Todd) . I just didnt have the chance to mess with any of the transmission stuff. What all should I do to my transmission in Ls1 edit. I would like firmer shifts but nothing that will cause too much stress on the transmission. What about Torque Management?
It would be perfect if I could get a list of all the things I can do to improve my A4 and some instructions on how to do all this. Thanks in advance for any and all help!

Re: Ls1 edit and A4 thanks! does anyone else have more info?
Ok I found the instructions on firming up the shifts..................
1) Select Edit > Transmission Calibration > Shift Firmness Tab > Positive Pressure vs Temp
2) You usually don't want to Firm up shifts when the Trans is cold, so Uncheck from -40 Degrees to 20 Degrees
3) We don't want to make much change in low TPS, around town driving,
but want to make a lot of change at 100% TPS.
4) Here is a tricky way to edit the whole table. Go to the "edit
whole table" Frame. Set the value to 110.
5) Push Mult % This raises all the values by a percentage - which may
seem very strange, because raising values will soften the shift.
6) hit Apply Changes
7) Now we firm it up, change the number in value to -108
8) Push Add Value
9) hit Apply changes
10) Select the check box for the low temps again, so all boxes are
checked.
11) Now look at all the curves together, you will see that I made no
change at 0% TPS, and a significant change at 100% TPS.
The result is that the more you depress the throttle, the higher the line pressure gets. This will leave you with reasonable shifts in around town driving, but stiffen up as you get more aggressive.
........................
If I were to follow these directions exactly would the -108 setting cause any pre mature tranny problems?
