Increased performance where applicable for stronger acceleration and improved working capability.
STEINBAUER application
Caterpillar C15 OHE Power Module
14.6L CAT C15
Increase from 429 BHP to 516 BHP and from 1,550 Nm to 1,880 Nm — without ECU remapping.
STEINBAUER performance module for the Caterpillar C15 OHE 14.6L CAT C15, designed to provide increased power and torque while retaining the original ECU programming and factory engine safeguards.
Key benefits
- Up to +25% power and torque increase, depending on application.
- No ECU software overwrite — the STEINBAUER system works alongside the original engine management.
- Injection duration module developed to add performance without generic one-size-fits-all mapping.
- Removable solution that can be removed if required.
- Application-specific development for the individual engine and vehicle or machine application.
- Efficiency — Stronger usable torque can help maintain progress at lower engine speeds with less unnecessary revving, which may support improved fuel efficiency in suitable operating conditions.
Actual fuel consumption depends on vehicle load, operating conditions, terrain and driving or operating style.
