Modification of Cummins 4ISBe chip tune: professional engine tuning for trucks and buses

Cummins ISBe series engines (4ISBe and 6ISBe) are widely used in buses (PAS, KAVZ, MAz), trucks (KAMAZ, Valday), as well as on special equipment and generator sets. The 4ISBe is a 4-cylinder diesel engine with a capacity of 4.5 liters, producing power from 150 to 200 hp. Factory chips often have reduced parameters to meet European emissions standards (Euro-3, Euro-4 or Euro-5).
Our service offers a modification service for Cummins 4ISBe, allowing you to purchase an individual tuning of your stock software instead of a pre-made file.

Features of the Cummins 4ISBe engine

The 4ISBe is equipped with turbocharging, common rail, high-pressure fuel pump (CPHD) and electronic control. The control unit is Bosch (EDC16, EDC17) or Cummins ECM. Characteristics of factory versions:

Power — 150–200 hp.
Torque — 550–700 Nm.
Capacity — 4.5 l.
Cylinders — 4.
The diameter and stroke of the cylinder are optimized for torque at low rpm.

After modifying the chip tune, you will receive a power boost of up to 30 hp and an increase in torque by 15%, as well as improved shift response.
