ECU-Remapping or engine mapping or chipping:


City Eelectro Diesel can offer professional ECU remapping in Swansea, we are the premier specialists in engine ECU remapping which sometimes refered to as chipping (and no not the fried kind!).

For many years engines have been controlled by an ECU (Electronic Control Unit), this monitors and supports the ignition timing and other areas to help keep your engine running.

Now what if your engine could be increased in power and fuel economy, well at CED's we can offer this service, our engineers will remap your car via the diagnostic port, there is no need to replace the chip and we don't usually have to remove or dismantle the ECU.

So what improvements can you expect?

  • Improved acceleration
  • Improved fuel economy
  • Smother power delivery
  • Improved throttle response
  • Turbo petrol cars typically get 20% more power 25% more torque
  • Turbo diesel cars typically get 25% more power and 25% more torque
  • Normally aspirated cars get 10% more power, improved throttle response

DPF Deletion

Our engineers can also help with DPF deletion, DPF (Diesel Particulate Filters), with their limited life span can cause many problems when they become blocked or reach the end of their serviceable life. DPF's can be prohibitively expensive to replace and removal is sometimes the only option. We are able to program many ECU's to enable the car to run without DPF.

EGR Deletion

In internal combustion engines, exhaust gas recirculation (EGR) is a emissions reduction technique used in petrol and diesel engines. EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. In a diesel engine, the exhaust gas replaces some of the excess oxygen in the pre-combustion mixture. If the EGR fails the car will run badly if at all. We are able to program the car ECU's to run without the EGR.
