I am tuning a EDC17CP46 ECU from a 2014 ML Bluetec and I got everything deleted and have a got an okay tune but the problem I am having is if I have the load in a certain range the ECU will shut down and lose communication with all the other ECU's. Sometimes it will do it and just go into a limp mode(reduced power) but still drive and other times it will shut down the ECU completely and I have to restart the vehicle and all is normal again. No codes in ECU but other modules have communication codes. I can duplicate the problem fairly easily just before 2k and higher loads. I am tuning with ECM Titanium and Ktag.
