ECM TUNING & CLONING SERVICE
✓ Tuning adjusts the software inside your existing ECM — no parts replaced — for more power, better response, and lower fuel consumption.
✓ Power gains of up to 30% are achievable, and in most cases fuel consumption still drops.
✓ Cloning copies your VIN, calibration, and immobilizer data onto a replacement module.
✓ All calibration work we perform is emissions-compliant.

What Is ECM Tuning?
ECM tuning is the process of fine tuning the software program that controls your engine's fuel management system, without having to replace any part. The result: more power, greater response, and lower fuel consumption.
We can increase the power of your engine by up to 30%. In 75% of cases, even with ECM tuning, you will still save on fuel. Optimal tuning also reduces your maintenance cost, since an engine with better combustion is a cleaner engine.
Tuning Benefits
The purpose of engine tuning is to adjust the parameters so the engine works better and more efficiently. Engines that operate more efficiently offer better fuel economy as well as power. One of the advantages of ECM tuning is that the software can be custom adjusted to how the operator actually uses the vehicle.
More power
When tuning for power, it is not unusual for operators to see up to a 30 percent increase in engine power. That is significant, especially where vehicles need to run with better overall performance under load.
Better fuel economy
ECM tuning can increase miles per gallon anywhere from 5 to 25 percent. That is a real saving on fuel, and it trims overhead and operating costs. Tuning for fuel economy is especially valuable for truck fleets, where annual savings can run from tens of thousands to hundreds of thousands of dollars.
Lower maintenance cost
An engine tuned for better combustion runs cleaner internally, which shows up over time as reduced maintenance expense.
What Is ECM Cloning?
ECM cloning is a technical process where existing engine computer information is duplicated onto a replacement ECM. That information includes the Vehicle Identification Number (VIN), engine calibration, and immobilizer data, and it allows a new computer to replace a damaged or malfunctioning unit.
Cloning is the standard solution when a module is physically beyond repair but the data stored on it is intact. The replacement arrives matched to your vehicle, so there is no dealer appointment needed to make it run.
Tuning vs Cloning
| ECM Tuning | ECM Cloning | |
|---|---|---|
| What it does | Adjusts the software that controls fuel management | Copies VIN, calibration and immobilizer data to another module |
| When you need it | The engine runs, but you want more power or better fuel economy | The module is damaged or malfunctioning and has to be replaced |
| Parts replaced | None | The module itself |
| Result | Up to 30% more power, 5–25% better fuel economy | A replacement module that runs your vehicle directly |
Emissions Compliance
All performance tuning we perform is emissions-compliant. We do not build, install, or supply calibrations that remove, disable, or bypass factory emissions equipment.
There is real performance available inside the compliant envelope, and that is where we work. Our tuning, cloning, and programming services are available for trucks, marine engines, and heavy duty and light duty applications, with nationwide mail-in service. See our repair process for how the service works.
