Default Speedo recal for TH400 with speed sensor

OK so I just installed a Rossler TH400 in my car. Car was a M6. Trans has a speed sensor in it. Anyone know what I need to change to make it read correctly? Thanks

I have the right connector I need to know what to change as far *** VSS info in the tune to get the speedo in line.

same thread, "I used my HPTuners software to delete all the references to the A4 trans and it has worked great, you can also use a manual trans program or ECM, but the speedo signal will need to be multiplied by 2.5 to read correctly."......is that what ur talking about?

So all you do have to do is use the speedo information from a stock A4 tune adjusted to your tire size.
You can just copy and paste it all, it's that easy.
Bingo that is what I was looking for. I know right now my speedo is reading very high. Like is says 100 and I am doing about 40
