Cummins Engine ECU Solutions: CM2350A, CM2250, CM2150E and CM850
Cummins diesels are among the most widely used industrial engines: they power Hyundai and Sunward excavators, XCMG and Zoomlion machines, trucks and buses. Whatever the brand on the outside, the engine ECU comes from Cummins’ CM family. Solutions for Cummins engine ECUs are available at ECU Prime.
