For anyone with the same rom id as me (A4TC300L) looking for a launch control patch. You can use the A4TC400L patch provided you do what I list below.
1. First you MUST MUST go to http://www.scoobypedia.co.uk/index.p...ilityList#toc2
and download the A4TC400L base map.
2. Make sure you have the rom that is on your car now saved somewhere or else you're going to be screwed in a minute. Once you download the A4TC400L basemap, go try and flash it to your car.
3. If it flashes to your to your car with out any error's, great, you can now use this map and the patch for it. The only pain about this is transferring all of your old map data to the new A4TC400L map. It really doesn't take that long.
4. After verifying it flashes and transferring all of your old map data to the A4TC400L map you can now patch it with tinywrexs patch and flash it!
I am not responsible if you mess anything on your car/ecu up.
