Power Remaps

Release the true performance from your engine. One of Eirtuning’s performance remaps will allow you to enhance the hidden performance of your vehicle. The overall torque will be noticeably increased, Power delivery will be smoother making for a more enjoyable driving experience, which in turn makes it easier and safer to overtake.
Throttle response will also be improved dramatically.

  • Improved drive-ability.
  • Better performance.
  • Increased bhp and torque.
  • Sharper throttle response.
  • Better pulling power.
  • All around a better balanced drive.
  • For Tractors & Trucks our special low down torque remaps make a vast improvement to HP and can have high MPG Gains.

Economy Remap

Extra torque provided by our remap at Low RPM reduces throttle input by the driver this in turn increases your MPG. This is a popular remap choice by many of our large fleet costumers where the extra MPG counts.

DPF & EGR Modification Software

A diesel particulate filter (or DPF) is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine.
Modern diesel vehicles are now fitted with a DPF (Diesel Particulate Filter). When driving, soot settles on the cell walls of the filter and starts to clog the pores of the DPF unit. This layer of soot can be burnt off during the regeneration process of driving at constant speed for a prolonged period of time, such as motorway driving. During short journeys or city driving, diesel cars do not reach the required exhaust temperature to allow regeneration to take place.

The EGR valve is a valve used to recirculate exhaust gases to cool the combustion temperature of your engine. These valves are prone to failure and are extremely expensive to replace.
We offer many EGR solutions on request.

ECU Cloning

 A facility we offer to copy or extract all the information from an old damaged ecu (even if it has no communication with a diagnostic tool) and upload this information onto a used 2nd hand unit.
