In my search for TCU tuning I found a tidbit from MBworld.org, a user there suggested Morendi for TCU tuning and to reach out to them by Instagram.
Well I did. The price is great at $750 for a TCU tune plus the cost of a tactrix 2.0 openport. The process is to hook up tractrix to a laptop, connect to internet, and allow them remote access to tune the TCU.
While not quite as elegant as a OBD dongle that you can switch back and forth on, it is pretty cool to get a TCU tune for seven hundred and fifty dollars. That is half the cost of solo motorsports.
