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 operating 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 come to you to talk through 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 and a full software backup are completed before any modification. The control unit can be restored to original settings at any time.
A custom software file is built specifically for your machine and then programmed back into the control unit.
We inspect and diagnose all relevant engine components. Each machine is tested before delivery, and we stand behind our software modification for as long as you own it.

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!
We know how important it is to boost your efficiently. 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.
