ECU Remapping

What is re-mapping?

ECU remapping is basically the modern term for what used to be known 
as “chipping” in the 1980’s and 1990’s.

All vehicles manufactured after 1999 are fitted with an onboard 
computer called  an “Electronic Control Unit” (E.C.U). The ECU monitors 
and controls the ignition timing, fuelling, air intake and boost pressure 
of an engine, and its parameters are pre-programmed from manufacture. 

The program installed by the manufacturer is set to allow for build 
tolerances into their engines  and to over comply with emission standards. 
It is also set to withstand operation in extreme environments,  cope with sub-standard fuel quality found in some countries and allow for some owners’ sub-standard service intervals and driving.


ECU remapping a vehicle re-programs the parameters within the ECU and the outcome is a much more responsive, fuel efficient and smoother running vehicle. The ECU remapping procedure may sound very complicated to some, and does indeed utilise extremely advanced technology, but in principle is very simple.

Find your vehicle’s tuning stats

What exactly is involved in re-mapping?

First we will need to plug our specialist equipment into your vehicle’s ECU port or socket. This is usually found underneath the dashboard or under the bonnet in the engine bay. Once plugged in, our equipment reads the ECU and downloads a computer file containing the relevant data needed to ascertain how the vehicle is currently performing. Then the file is analysed and a new file containing totally new parameters is uploaded to the ECU and hey presto!

All immobiliser and chassis information is safely retained upon this procedure.

We feel it is also important to mention that, all of our remaps are custom written on the day, are 100% unique to each individual vehicle that we carry out work on, and not ‘off the shelf’ pre-programmed ‘problem files’ that so many companies do use.

Does a vehicle need to be fitted with a turbo to benefit from a re-map?

No. Although a vehicle fitted with a turbo system will benefit the most, a normally aspirated engine can also benefit from up to a 15% increase in power with careful adjustments within the vehicle’s ECU.

How long does it take?

This can take anything from thirty minutes to two hours, depending on the make and model of the vehicle.

We can also come to you, so there’s no need to take time out from your work or home life.


Il servizio di remapping consiste nella rielaborazione del file della centralina dando degli incrementi su tutti i valori di essa; cosi da aumentare le prestazioni del veicolo.


Questa operazione permette di risolvere definitivamente tutti i problemi causati dalla valvola EGR


La rimozione dei DTC (Codici di guasto) consente ai nostri clienti di cancellare gli errori fittizi della centralina, che non causano malfunzionamenti alla vettura ma solo l'accensione della spia motore.


Ripristinando il sistema si prolunga la vita della batteria, del motorino di avviamento e del motore.


Tutte le moderne autovetture sono dotate di un limitatore di velocità elettronico. Oggi questo può essere rimosso o riadattato e permettere al cliente di modificarlo secondo necessità.


La rimozione delle valvole flaps o swirl guaste, facilita l'avviamento della vettura e riduce la fumosità a minimo. Permette, inoltre, di evitare che le valvole guaste si stacchino dalla loro sede e finiscano all'interno dei cilindri.


La perdita di potenza a bassi regimi, i seghettamenti, l'eccessivo consumo sono tutti sintomi del malfunzionamento del debimetro. Con questo servizio si può ripristinare il debimetro e risolvere tutti i problemi.


Le auto di ultima generazione prevedono l'utilizzo di un additivo chiamato "ADBLUE", sostanza utilizzata dai truck, molto costosa da riassortire. Oggi possiamo intervenire elettronicamente emulando l'impianto elettronico ed inibirne il funzionamento.


Il launch control è un sistema derivato dalla Formula 1. Permette di ottimizzare la potenza e la coppia nelle prime marce ed a bassi regimi, ottenendo le partenze scattanti e sorpassi agevolati.


La sonda lambda è un sistema che controlla le emissioni dei gas di scarico nei motori a benzina. Essa è soggetta a periodici guasti e malfunzionamenti. Emulandola si avrà una combustione ottimale, riducendo seghettamenti e spreco di carburante.

What is a DPF?

dpf removalD.P.F. (Diesel Particulate Filter) is a filter fitted to the exhaust system that is very similar to a catalytic converter in looks. It is designed to remove diesel particulate matter or soot, and the objective is to produce cleaner exhaust gases.

However, as many people will agree, they often cause a lot more trouble than they actually do good.

As with any type of filter, a Particulate Filter needs to be cleaned regularly to function properly.

With Diesel Particulate Filter this is done by a process known as regeneration.

This involves a combination of  functions in the Diesel Particulate Filter system to burning the soot to a very high temperature!

Regeneration should be an automatic process taking place in the normal use of your vehicle, you may have noticed this in the form of a blast of white smoke from the exhaust on occasions.

Diesel Particulate Filters have been in common use in passenger cars and light commercials from around 2003 in preparation for Euro 4 regs (2005), with Peugeot, Renault and BMW being early takers.

Euro 5 (2009) made it compulsory for diesel cars and light commercials to have a DPF fitted and Euro 6 2014 will tighten this up further.

Problems encountered with DPF

If regeneration doesn’t function properly it leads to a build up of soot affecting performance and fuel economy.

Left unattended this will result in a blocked DPF which can ultimately cause very expensive damage to other engine components. A blocked DPF is also potentially dangerous as it can cause overheating in the exhaust system and in turn presents a fire risk.

To prevent this damage most newer vehicles will go into “limp home” safety mode at this stage, meaning the vehicle will have minimum power!

For regeneration to take place it requires the vehicle to be driven regularly at some speed on open roads e.g. motorway driving, typically driving at around 2500 RPM for approx 30 minutes at least once a month, this will keep things working, however, many diesel vehicles are used primarily in urban areas or on short journeys, e.g. local deliveries, taxis, school runs etc,  So the vehicle does not get the chance to heat up sufficiently and is unable to carry out a full regeneration process.

Even if the regeneration functions as it should, over time the ash residue will build up in the DPF and have the same affect ultimately resulting in a blocked Diesel Particulate Filter.

For this reason a Diesel Particulate Filter is classified as a serviceable Item by the vehicle manufacturers, like brake pads or air filters etc, and not covered under warranty. Diesel Particulate Filter systems therefore need to be maintained properly.

Dashboard common symbols

If your DPF warning light or Anti-Pollution warning is on dash, please do not ignore it and get professional advice!

Leaving it will ultimately cost you much more in additional repair bills and as mentioned above, it can be dangerous.

dpf warning lights

What are my options?

By the time your DPF warning lights are visible, your DPF will already be significantly blocked.

Forced regeneration by a garage or a “blast down the motorway” is not likely to cure the problem, these only work as preventative maintenance.

So at this stage realistically you have the following 4 options:

Replace the DPF filter with a genuine OEM part with an average price starting from 1800EUR.

Replace the DPF filter with an after market part, but we strongly recommend against this. As after market DPF filters (in our experience) Don’t  last very long and can also be very troublesome to fit.

Have the Diesel Particulate Filter filter cleaned as we are part of the DPF Doctor network.

Removing the DPF altogether is a guaranteed solution at a fraction of the cost of replacing it, and all our DPF removals are done to be MOT friendly.

Contact your nearest ChadRemapping Agent now for free expert advice.

We guarantee you will receive friendly, knowledgeable advise & will make huge savings over main dealer costs.

All our DPF removals come with a lifetime guarantee on software.


The remapping service consists of reworking the file of the control unit by increments on all its values; thus increasing the performance of the vehicle.


This operation will permanently resolve all problems caused by the EGR valve


Removing DTCs (Failure Codes) allows our customers to erase faulty drive failure, which does not cause malfunction to the car, but only ignition of the engine warning light.


Restoring the system extends the life of the battery, starter and motor.


All modern cars are equipped with an electronic speed limiter. Today this can be removed or adapted and allowed the customer to modify it as needed.


Removal of face valves or turbulence is defective, facilitates the start up of the car and reduces the minimum smoke. It also prevents the valves from squeezing from their seat and finishing inside the cylinders.


Low power loss, segments, excessive consumption are all symptoms of the debimometer malfunction. With this service you can reset the debimometer and solve any problems.


The latest generation cars are using an additive called "ADBLUE", a substance used by trucks, which is very expensive to reassume. Today, we can electronically emulate the electronic system and inhibit the operation.


Launch Control is a Formula One System. It allows you to optimize power and torque in the early gears and low ranges, getting kicking startups and overcoming agility.


The lambda probe is a system for controlling exhaust emissions in petrol engines. It is subject to periodic failures and malfunctions. Emulsifying it will have optimal combustion, reducing signs and waste of fuel.
