John Deere ECU Remapping

John Deere tractors are some of the most respected machines in the agricultural world. Known for their durability and build quality, they are a staple on farms across the UK. However, like most modern tractors, John Deere models leave the factory with conservative ECU settings that restrict performance to meet emissions regulations across multiple global markets.

We can safely and effectively enhance your John Deere tractor’s engine management system — giving you the performance your machine is truly capable of.

As mentioned, most modern farming vehicles come equipped with advanced ECU systems that control the performance of how the engine behaves, these settings are often “detuned” at the factory to:

Meet international emissions standards (EU, USA, etc.)
Allow one engine to be used across multiple power models
Increase service intervals and warranty margins for the manufacturer

Whilst these settings are ideal for global compliance, they often result in:

Reduced torque and pulling power
Higher fuel consumption
Flat throttle response
Slower work rates in the field

Does this sound familiar? With our ECU software, we can increase horsepower & torque whilst often reducing fuel consumption.
