ECU Remapping

Economy Tuning

If you're looking to save money on fuel while still gaining sharper throttle response and reduced turbo lag along with additional power and torque then an economy engine remap is the product for you!
Our economy remap software is developed to work on a standard vehicle maintaining manufacturer levels of reliability and original service intervals. Ecomap is specially designed for improved power & maximum economy.

  • Designed to return an improved economy in turbo diesel engines.
  • By re-characterising the torque limits on the engine, at lower rpm’s you will benefit from additional performance and improved economy.
  • At higher rpm’s the software will encourage shifting up through the gearbox, to keep the engine running in its optimal window.
  • Ecomap is a very popular choice with large fleet owners, where the extra mpg improvement counts on the bottom line profit.


Our technicians have developed a unique range of tuning services which can deliver the very best in economy tuning. They provide significant gains in fuel efficiency whilst improving the feel and drive-ability of the vehicle.
All manufacturers have to limit the power and mpg of their vehicles in order to adhere to the many different markets they face due to simple things such as differing fuel grades around the world to issues with marketing and affordability. As a result your car will always under-perform for both power and fuel efficiency.
We have perfected our economy tuning software to deliver the optimum economy while also providing an increase in power at the same time.

Van tuning:

We are also very proud of our custom tuning on all transits including the latest Euro 5 models. (Euro 6 tuning is here)

Ford Transit tuning specialist contact us for more details. We can tune any transit.

Mercedes Vito, Sprinter tuning as well as all Vauxhall Vivaro, Combos and Renault Traffics including the latest twin turbo models.

One case study is for a local motorfactor based in Kent and Essex who have a large fleet of Citroen Nemo, Despatch and Berlingo vans. We have seen upto 10mpg improvement on these from a simple economy tune.

Just because your van is not a "performance" vehicle does not mean it isn't tune-able in fact some of our biggest BHP gains are on commercial vehicles. Some of the sprinters and crafters can gain nearly 100BHP.

Not only does the tune improve your MPG but low down torque and drive-ability especially with a laden vehicle or when towing.

We specialise in tuning motorhomes for power and economy. We take pride with your vehicle and a full before and after health check is supplied.

Optional Extras

Hot Start Fix
If a pd Diesel engine starts easily and quickly when cold but struggles to start when hot, this is described as a Hot Start Problem.

These diesel engines are started by an ECU and not by the driver. Pressing the accelerator pedal has no effect during a starting procedure. Starting is actually controlled by a ‘starting map’ in the ECU and is based on starter/engine speed (rpm) and injected fuel quantity (iq).

Generally, the ECU will not allow start fuel injection until the engine rpm is above a fixed map value.
Such problems can occur from low battery charge, engine coolant temperature sensor faults or the starter motor itself.

However, the problem may be the actual Hot Start Map within the ECU.

Lambda/O2 Delete
O2 Delete remaps are for those who have fitted either sports­cats or de­cat pipes within their exhaust system and are subsequently having problems with the engine light being triggered due to emissions faults for error codes P0420 and P0430 (Cat efficiency). We can solve this problem by disabling these checks within the ECU map.

Launch Control
Impact Tuning’s Launch control Software manages the amount of power to the wheels optimum traction is achieved.

From 2-4 MPH the RPM is limited to 2500-2750rpm. Once the pre-determined speed is reached the RPM Limiter will automatically move to normal RPM and from that point maximum power is allowed.

MAF Delete (MAF to MAP switch)
MAF deactivation is not recommended as it is a very important sensor for fuel regulation, but sometimes (normally on high powered tuned cars with bigger turbo/injector modifications) the MAF reading hits its maximum value and touches the maximum allowed voltage read by the sensor making a fault code in the ECU and places the vehicle into a safe mode (limp mode).

On vehicles so equipped, this alternative involves the use of a manifold absolute pressure, or MAP, sensor. The MAP sensor measures pressure in an engine’s inlet manifold. When coupled with RPM data, and a table of volumetric efficiency over the operating range of the engine, the MAP sensor can be used by the engine management computer to calculate fuel requirements.

Speed Limiter Removal
Many vehicles are programmed with a top speed limiter. Our speed limiter removal software allows the vehicle to reach its top speed. However, we are mindful of international road and highway laws and take the opportunity to stress our service is intended for track use only.

Start/Stop Disable
Many people do not like modern Start/Stop systems (which turns off the engine every ­time they stop), but it’s becoming increasingly common on new vehicles. Normally, there is a disable button, but this has to be reset every ­time the engine is restarted. With our Start/Stop Disable ECU remap, the function is disabled permanently.

Swirl Flap Removal
Intake manifold flap failures are common on certain groups of cars and are expensive to replace. Our software can be used as part of a flap removal operation without causing fault codes or engine management lights.

Speed limiters:

Have you bought a van with a speed limiter? At Impact Tuning we can remove the majority of speed limiters. We can remove all Ford Transits, Transit connect, and Ford Transit customs.

We can also remove Vauxhall Corsa, Combo and Vivaros as well as Renault Traffic and Masters. Mercedes Sprinters are trickier but again no issues for us.

So whilst getting your tune done why not get your limiter removed and free up your vans full potential/
