How does it work?
Todays diesel engines have many sensors which are controlled by the vehicles ECU these signals are processed many thousands of times in one second to maintain that the vehicle is running at its optimum efficiency and keeping the emissions and economy at acceptable levels. The idea behind the tuning box is to intercept the signal between the ECU and the injection system usually the common rail and basically allows it to inject more fuel into the cylinders thus producing more torque and power, and because of this the engine is running more efficiently the fuel consumption is also improved because you would have to use less throttle for similar conditions.

So why don't the manufacturers do this....
You may have wondered why a manufacturer can have the same engine in different models but they can have different power outputs. This is not due to the engine mechanics as they are usually built to the same standard, but its down to the software installed into the ECU which governs the engines output. Manufacturers do this because of the strict emissions regulations and tax bands especially for the company owned driver. Many countries around the world relate their tax levels to the KW output of a vehicle or the emission levels.

Installation:
All ChipMyCar Systems have been designed to be compact and easy to fit they are supplied complete with the correct OEM wiring loom and connectors for the vehicle application and can be installed with the minimal of mechanical ability thus making it an ideal DIY project, most units can be fitted in around 10 minutes and they come complete with full support.

Will I get better fuel economy?
As it increases the efficiency of the engine, you should see an improvement in fuel economy. This improvement depends on your driving style and the engines condition. Normal results are 10%, however, we've seen results of up to 15-20% in some cases.

Why will I get better fuel economy?
More engine power means you can achieve the same driving style with less RPM and gear changes. This results in better fuel economy.
Why don't manufacturers build the engines optimised from the start? One reason is simply to allow the manufacturer to release 'Sport' models. With these models, the manufacturer just does the same thing as the Chip My Car tuning box does (except directly within the ECU). This means they can produce faster and better fuel economy vehicles without having any additional costs. They can then charge more money for the privilege!

Does it work with automatic vehicles?
Yes. It is compatible with both manual and automatic gearboxes.
