Detroit Diesel Engine Programming

The Detroit platform we see most is the DD15 in Freightliner Cascadias — one of the most common Class 8 highway diesels on the road. Detroit calibration work is different from Cummins or Paccar because every job is dual-module: the CPC4 ECM handles engine management, the ACM3 handles aftertreatment. We program both together, including ACM3 recovery on modules the dealer has given up on.
