I will definitely keep everyone updated as i progress thru this. I built a 2nd board as a spare and they are both currently waiting to be tested on the xfire once the better weather finally arrives and the car comes out of hibernation. I also have a friend with a e55 wagon that will likely be a candidate for one tcu controller, and setting up some fun shift modes.

Obviously yes, this isn't in its current form a set it and forget it type of tcu controller for the masses. But offers full customization for those who can and want to tinker. But i honestly have full respect for Rand_Ash for the time spend, development, and reverse engineering hours he has spend on this project. Its a serious feat, and im honestly very grateful that these types of home brew type ventures are becoming capable as tech evolves.
