With fuel, maintenance and other operating expenses pressuring budgets, finding ways to cut costs and improve efficiency is more important than ever. Optimizing routes, reducing idle time, and improving vehicle maintenance can help, but one strategy fleet managers may be overlooking — one that goes “under the hood” — is engine calibration. By adjusting certain engine operating parameters to better match how vehicles are used, engine calibration can offer fleets numerous benefits. ## **Engine Calibration: A Look Under the Hood** Fleet vehicles perform diverse tasks, often under a range of conditions. When they leave the manufacturer, their engine settings are typically configured to accommodate a broad mix of applications, rather than the specific needs of an individual fleet. That’s where engine calibration comes in. Engine calibration, which is performed by an engine calibration specialist after a thorough consultation on a fleet’s specific needs, is a process that adjusts a vehicle’s engine control module (ECM) by implementing customizations to the software coding that tells the engine how to run. These modifications refine engine parameters to a vehicle’s specific needs, thereby reducing fuel usage, protecting drivers, and minimizing fuel spend. Depending on the vehicle and its manufacturer-approved capabilities, these adjustments can include: - **Vehicle Speed Limits:** Setting maximum speeds to help reduce fuel consumption and promote safer driving. - **Idle Settings:** Limiting unnecessary and [excessive idling](https://blog.psenergy.com/excessive-idling) to reduce fuel waste, harmful emissions, and engine operating hours. - **Engine Speed and Torque Limits:** Managing engine operation to support fuel efficiency and appropriate vehicle performance. - **Transmission Shift Points:** Optimizing gear changes to improve efficiency under specific operating conditions — where supported. Customizing these settings helps vehicles run more efficiently without compromising job performance. ## **What Is the Calibration Process?** Engine calibration begins with an evaluation of your fleet vehicles and operating requirements. Factors such as vehicle type, routes, driving conditions, typical loads, and fuel consumption help determine which adjustments could provide the greatest benefits. After determining the adjustments, an engine calibration specialist uses compatible diagnostic or programming equipment to access the vehicle’s ECM and adjust the parameters. It’s crucial that all adjustments comply with manufacturer specifications, warranty requirements, and emissions regulations. Depending on the vehicle, the process may involve connecting a programming device to its diagnostic port and updating the appropriate settings. Many adjustments can be made without mechanical modifications, but the time required varies by vehicle and calibration. Once the settings are applied, the vehicle should be tested to ensure the adjustments are functioning properly and delivering the intended results. ## **What Are the Benefits?** When properly implemented, engine calibration can provide numerous benefits for fleets, including: - **Reduced Fuel Consumption:** Optimizing vehicle speed, idle time, and other operating parameters can help reduce unnecessary fuel consumption and lower overall fuel expenses. - **Improved Driver Safety:** Establishing speed limits can help discourage excessive speeding and reduce accident risk. - **Lower Maintenance Costs:** Reducing unnecessary engine idling and excessive engine hours can help limit wear on engine components and potentially reduce maintenance frequency and costs. - **Extended Vehicle Life:** Limiting excessive engine speeds and reducing unnecessary engine wear can help extend vehicle life and maximize ROI. - **Greater Operational Efficiency:** Aligning engine settings with vehicle applications can provide a better balance between fuel efficiency and performance. - **Support for Sustainability Goals:** Reducing unnecessary idling and fuel consumption can help lower emissions and support sustainability goals. ## **Is Engine Calibration Right for Your Fleet?** No matter what type of vehicles you have in your fleet, reviewing their available engine settings may uncover opportunities to improve efficiency and reduce costs. To determine if engine calibration is right for your fleet, work with a qualified engine calibration specialist who understands your vehicles, operational needs, and manufacturer requirements. A specialist can help identify opportunities for adjustment and determine whether engine calibration would be a cost-effective, long-term investment for your fleet operations.     #### Subscribe #### Latest Posts in this Topic - [Weight Distribution for Fuel Efficiency](https://blog.psenergy.com/weight-distribution-for-fuel-efficiency) - [Predictive Fleet Maintenance and Fuel Data: How Smart Fleets are Cutting Costs](https://blog.psenergy.com/predictive-fleet-maintenance-and-fuel-data) - [Excessive Idling: Are You Spending Fuel Going Nowhere?](https://blog.psenergy.com/excessive-idling) #### Topics - [Fleet Management](https://blog.psenergy.com/topic/fleet-management) - [Fuel Management](https://blog.psenergy.com/topic/fuel-management) - [Asset Management](https://blog.psenergy.com/topic/asset-management) - [Risk Management](https://blog.psenergy.com/topic/risk-management) - [Industry News & Reports](https://blog.psenergy.com/topic/industry-news-reports) #### Address 4480 North Shallowford Rd Suite 100 Dunwoody, GA 30338 #### Phone (770) 350-3000 #### Connect With Us - - - - Energy Services - [Fuel Management](https://psenergy.com/fuel-management/) - [Emergency Fueling](https://psenergy.com/emergency-fueling/) - [Asset Management](https://psenergy.com/asset-management/) - [Green Energies](https://psenergy.com/green-energies/) - Who We Help - [Fleets](https://psenergy.com/fleets/) - [Facilities](https://psenergy.com/facilities/) - [Utilities](https://psenergy.com/utilities/) - [Airports](https://psenergy.com/airports/) - Resources - [Resources](https://psenergy.com/resources/) - [Blog](https://blog.psenergy.com) - [Our Strong Commitment to Supplier Diversity](https://psenergy.com/about-us/) [Get In Touch](https://psenergy.com/contact-us/) PS Energy ![National Minority Supplier Development Council](https://psenergy.com/wp-content/themes/PSEnergyV2/images/nmsdc.png) ![Certified Women's Business Enterprise](https://psenergy.com/wp-content/themes/PSEnergyV2/images/wben.png) ![Women Owned Business](https://psenergy.com/wp-content/themes/PSEnergyV2/images/women-owned.png) Copyright © 2023 PS Energy Group, Inc.
