💻 ECM Programming on a Military C7 Caterpillar. We’re working on a military C7 truck where the original programming has been lost. We tested all 4 input options in the configuration tool, but none worked — likely due to a custom military setup. ⚙️ Luckily we’re getting the program from a twin truck at the base to transfer it and finish the job. 📡 💬 Comment "Result" if you want to see the final result. #ECMRepair #TruckMaintenance #Caterpillar | Oscar Truck ECM
