London Road Garage Performance Tunes......

......Frequently Asked Questions

What Is Remapping & Performance Tuning?

Remapping or performance Tunes are modifications to the manufacturer's vehicle tune data. These modifications are mostly downloaded to the vehicle's Engine Control Module (ECM) through the on-board diagnostics 16 pin connector. Later vehicles may need to have the ecm removed to be programmed directly

What are the benefits?

• Increased power and torque

• Smoother delivery of power

• Increased fuel economy in most diesel applications

• Sharper throttle response

• Faster acceleration

• Reduced number of gear changes

Why do manufacurers limit the power output?

The standard manufacturer tune map is a compromise of many of factors. Primarily, the manufacturer must ensure a high degree of engine reliability across the various worldwide markets, taking into account factors such as:

• Fuel quality

• Different servicing schedules

• Different operating environments, such as altitude   and terrain

• Local emissions legislation

During testing, manufacturers “manipulate” the tunes constantly to achieve individual results for individual tests, thus compromising the overall smoothness of the original tune. Performance Tunes are optimised for European driving conditions. As long as the correct service schedule is maintained, there is no reason why this extra power cannot be ‘unleashed’.

Will the emissions be affected?

All of our tune files are checked & tested to ensure that they comply with UK emissions standards.

Can the process be reversed?

Yes the original file is retained & can easily be reinstalled if required.

" This thing is going to eat brake pads. 4th is the new 3rd, & definitely more torque gain than bhp. It has changed the car. The car now feels very light. I Haven’t been able to fully open it up yet, Ashby to Castle Donington was very lively & economy is there too......"

" Great stuff Dave thanks. Looks like I will have to swap the flat cap for a baseball cap! Motorway overtaking is so much easier now. Great value for money. :-) ......”
