Cummins PowerSpec is an electronic tool that makes it possible to tailor the operation of Cummins engines in every on-highway engine application.
PowerSpec's full functionality is available to support all Cummins 2007 products (ISX, ISM, ISL, ISC, ISB), 2010 engine products (ISX15, ISX12, ISL9, ISC8.3 and ISB6.7), 2013 On-Highway engine products (ISX15, ISX12, ISL9, and ISB6.7), 2017 products (X15 Efficiency, X15 Performance, X12, B6.7N, L9N, ISX12N), some of the Natural Gas products (ISL G and ISX12 G) and earlier products.
Features include a gearing calculator, complete descriptions of electronic features, instructions on how to optimize parameter settings, and access to trip information and fault code data. It also supports fault codes and trip information on Euro 3/4.5/5, ISBe, and N14+. Other functionality is not available for the Euro 3/4.5/5, ISBe and Celect Plus engines.
PowerSpec can be downloaded, at no charge, to any PC running Windows 7 SP1, Windows 8.1 or Windows 10. You will need the INLINE 7 adapter cable, available for order at the Cummins PowerStore or through your Cummins distributor, to communicate with and gear your vehicle, configure electronic features, and read engine data. *PowerSpec works with most rp121032 compliant adapters.
- The use of PowerSpec is supported in North America only. For engines equipped with a Diesel Particulate Filter (DPF), Ultra Low Sulfur Diesel Fuel is required. Failure to do so can permanently damage engine and aftertreatment systems within a short period of time. This damage could cause the engine to become inoperable and affect the warranty coverage on the engine.
- Licensing: PowerSpec does not require a license to connect to a vehicle, read data, or use the gearing calculator. A license is only required to write changes to the adjustable features.
