Tractor output changes can offer haulage fuel savings

Owners are turning to professional engine remapping, from specialists such as Avon Tuning HD, to better match tractor power to certain applications or implements.

Gareth Jones from Avon Tuning HD says that for jobs that don’t require a PTO, such as cultivations and trailer work, this is returning some real-world fuel savings by increasing the efficiency of the application.

“If a tractor achieves peak power at 2,000rpm, it must always be operating at its limit to achieve it. By changing certain parameters in the ECU, we can bring the peak power delivery to 1,600rpm, meaning the tractor doesn’t have to work as hard to achieve the same output and fuel savings can be achieved.”

By matching output to certain applications, Avon Tuning HD says it can safely improve performance within the engine’s capabilities. When applying an economy specific remap, Avon only adjusts key parameters such as fuel injection and torque limitation in the mid- and low-range, therefore top-end rpm performance is not changed.

These changes allow operators to run in a higher gear at lower revs to benefit from the additional low-down peak power. “This is noticed when ploughing or cultivating, especially if the implement has forced the tractor to work consistently at its limit before a remap. Fuel savings of between 5% and 10% are achievable in some situations,” says Gareth.

Before applying any remap, the tractor’s characteristics are cross-referenced to make sure any increase in power can be handled by all the component parts.
