Economy calibration is meaningful only when the work can be measured. Route, payload, driver, idle time, gearing, tyres, maintenance, weather and operating speed can have more influence than a software change.
Define the operational baseline
Before ordering, record fuel use over a representative period and describe the unit of work: kilometres with comparable payload, hectares with the same implement, operating hours at a defined load, or another repeatable measure. One unusually good or bad journey is not a reliable baseline.
Gradients, stops, towing and average load shape the objective.
A progressive working range may help reduce unnecessary gear changes or engine speed when conditions allow.
Tyres, alignment, injectors, boost, filters and maintenance must be correct first.
Before and after data must use a meaningful period and similar conditions.
Required file and fleet information
- Original ECU read and complete identification for each unit.
- Truck, tractor or machine configuration and transmission.
- Route profile, typical payload, working cycle and idle pattern.
- Baseline method, period and current consumption.
- DTCs, maintenance state and hardware changes.
- Any drivability issue that affects the current result.
No universal saving claim
BLAG does not publish a guaranteed saving because the outcome depends on operation and measurement. The file cannot control traffic, driver behaviour, load, tyre pressure or mechanical condition. The correct target is a technically coherent calibration and a fair comparison of fuel used for equivalent work.
Read the dedicated truck and fleet page or agricultural calibration page for sector-specific preparation.
How to judge the outcome
Use the same calculation before and after: fuel added or consumed divided by comparable distance, hours or completed work. Note payload, route, implement, weather, idle time and driver. Short dashboard averages can reset, smooth data or hide regeneration and idle events. A useful review needs enough operation to reduce random variation. If the duty cycle changes, keep the periods separate. Report drivability and diagnostics alongside consumption; reducing a displayed number is not a valid result if temperatures, smoke, gear use or reliability deteriorate.
