Car is home from the shop assuming I can get my a/c working this week I should be able to give you my thoughts fairly quickly
Going to be very interesting. Looking forward to your thoughts. The TCU tunes are a very cool subject. There is a guy who goes by Rand_Ash on YouTube. He built his own TCU from scratch with much more powerful processors than the stock Siemens TCU. The benefit is that he can literally use this open source TCU on just about any vehicle not just limited to the 722.6 tranny.
I have been following his work for a while. He has a telegram group where testers use his custom TCU in numerous different Mercedes models (there is one or two crossfires there also) and he releases tweaked software regularly. His TCU is not perfect yet but I was very very impressed by the shift times and the capabilities of his product.
I can't wait to see where he takes it. The guy is a genius and very very capable plus he is a good dude who genuinely cares to make this project work and perfect the TCU of these vehicles and beyond. FOr anyone who's intrigued, watch his YouTube videos and check out his website.
