just a little info on how this works (I think)
Its basically fooling the TCU into thinking you hit the brakes, which normally unlocks the convertor, so your TCU is thinking you hit the brakes and keeps the TQ unlocked (this is also why the cruise control turns off when you hit the switch because your CC always shuts off when you hit the brakes

As for the sporttronic shifting, it can/will work just fine someone just needs to do it, if you havent by july I will do it again and this time hook up to the TCU and not the ECU like last time (I thought the TCU was part of the ECU but Im incorrect the TCU is under the dash kind of behind the radio on the firewall from what Ive heard.
Id do it but Im sooo busy with moving to NC from chicago
