When tuning an A4 on a dyno, do you lock up the TC in third?
Sorry for a stupid question but, I've never tuned an auto before on a dyno so I need to know where to lock her up. TIA.

Hi John,
Usually they hold 3rd gear and lock the TCC...
In the scantool:
- goto the DVT tab,
- select your controller (e.g. Gen III 99-08 LS1),
- press the Activate button,
- goto the Auto Transmission subtab,
Place a checkmark in the box for each of these:
- Activate Transmission Gear Control,
- 1999+ TCC Enable Solenoid (use 1998 if you have a 1998),
- 1999+ TCC Control Solenoid (use 1998 if you have a 1998),
Then press these buttons:
- Hold 3rd,
- TCC Enable Solenoid Turn On (the one for 1998 if you have a 1998),
- TCC Control Solenoid 100% (or Turn On if you have a 1998).
If you goto the dash tab, and if you are logging GEAR and TCCMODE you should see 3rd gear and TCC locked.
