I have a Challenge Stradale TCU for sale (reference part number 196986). This TCU has been flashed to CS firmware and is fully working. It's a great upgrade for faster and smoother gear shifts. It also has the advantage over early model TCUs of having an adjustable PIS setting. It will fit any 360, and of course the Challenge Stradale. This part is an easy install and also reversible. - Will ship worldwide - US $1800 Please send me a PM.
