Engine Control Unit Tuning
Field-Tested Power. Real Fuel Savings.
Performance Agricultural Equipment Tuning
At Grits & Gears, we enhance the performance of agricultural equipment, construction machinery, and trucks through advanced Software Modifications and Engine Performance Optimizations, such as ECU tuning.
We aim to increase fuel efficiency, torque, and overall machine productivity, helping operators reduce costs while maintaining reliability
Custom-built ECU tunes designed specifically for your tractor model, its place in the series, the equipment you’re pulling, and how you want it to perform in the field.
More power and torque where you need it, better fuel efficiency, and stronger response under load—without buying a bigger machine. Built by farmers who run the same equipment and know what actually works when the work starts.
More Power. Less Fuel. Built for the Way You Farm.
We will discuss your needs and what you expect from the machine. Performance matters to us, so we take the time to get those details right before any work begins.
Diagnostics, backups, and safeguards are completed on your machine.
Machine-specific tuning is completed on the ECU file and then programmed back into the control unit.
We verify the success of the diagnostics and tuning work once completed.

What will change in the engine?
The modification fine-tunes key engine parameters, including injection timing, air-to-fuel ratio, injection duration, fuel quantity, and the torque limiter.
Turbo-diesel engines can see performance gains of up to 30% and torque gains of up to 25%.
Torque improves most in the low- to mid-RPM range, where field work actually happens.
Fuel use can drop by as much as 18%.

Why reprogramming makes sense.
Precision Software Adjustments
We adjust key engine settings—injection timing, air-to-fuel ratio, turbo boost, and torque limits—entirely through software.
Safe and Non-Invasive
No hardware is added or replaced. The work is done with the control unit software, so your machine stays intact, protected, and running stronger and more efficiently than before.
Benefits and Return on Investment
We know how important it is to boost your efficiency. If you can get your equipment to cover more acres in less time, you can save thousands of dollars in fuel, labor, equipment depreciation, and countless hours of time every season.
