INSITE 8.9 System Requirements — What You Need
Cummins INSITE 8.9 has specific hardware requirements that differ depending on what you plan to do with it. Reading fault codes requires minimal hardware. ECM programming and calibration downloads require the official Cummins INLINE 7 adapter and a stable internet connection — a missing detail that causes expensive failed programming sessions in the field.
