Short info.

The N/A version works. There is a little cold start problem with the sotware. So for the first 500 metres the transmission doesn't change gears in automatic mode - so you have to change gears manual. This isn't solved yet. There are some Crossfires running the software without any other problems. The guys that bought the TCU software are all pleased with the result, because gear changes are also a little faster.

The SRT6 / C32 version works like a charme without any problems.

Evotech charges 500 euros for the TCU software update. I think if you ask for a group buy you'll get a 20% rebate. If you're interest in a group buy, please ask Evotech directly. They also have a dependance in the US.
