FAQ's

The combined data of both fuel mixture and ignition timing of “open loop” digital systems are held on a chip within your Electronic Control Unit (ECU). This data is then used by the ECU programme to set ignition timing and fuel supply to the engine as required. The data (or “characteristics” of the information) can be depicted as a graph which, when analysed and altered, is known as engine (re)mapping.

Quite simply, it changes the data in various areas to provide a different map so that elements such as the fuel supply, ignition timing, injector opening times etc.. are altered to provide more efficient combustion/engine performance.

When a manufacturer releases a car into the market, the vehicle has to be able to cope with pressure coming from many different environments, by many different users, and all elements must be “off the shelf” to respond to many demands whilst still being economical to produce. For example, the car has to cope with possible poor fuel quality, dusty environments, poor servicing and at the same time provide reliability and economy. This has meant that, historically, manufacturers may ‘detune’ the engines to cater for all this. As the market is relatively compact, engines compete within certain ranges: they perform in a similar way. When the vehicle is sold in a variety of countries, it will have to be engineered so that it is still respectful of emission regulations, as well as a variety of weather conditions (heat, altitude, humidity, etc..). If the engine is mapped to produce, say, 105bhp officially, it will need to be mapped to hit its official figure in all countries where the car is marketed. Engine performance is therefore optimised for the countries in which the vehicle is sold. It is capable of more than it is mapped to do. Cornwall Remaps stretch that metaphoric ‘elastic band’, overcoming the state of compromised tuning most UK motorists know and experience with their cars.

OBD Engine Mapping is the modern version of ‘chipping’. When you “chip” a car you basically put in a chip that has a set of data already burnt onto it, into your ECU. When you OBD remap an ECU, you save the data currently stored on the chip and overwrite it with the performance data. This then allows you to apply different maps, where applicable, as well as restore the original data – should you require it. As no standard part of the car has been changed, warranty is unaffected. Angel Tuning’s ‘remapping’ is a real, standard version of engine tuning, using a modern approach.

It is difficult to predict an exact figure for each car. However, for both normally aspirated petrol diesel engines, we expect to gain 10%. For example, an 83bhp 1.2 Punto will gain 8bhp, as well as 8lb ft torque. For a turbo derivative, bigger increases are expected: some 35bhp on, say, the 1.9 JTD and a massive 60bhp+ on the 2.4 JTD Fiat engines, to stay in theme.

No change is carried out to any of the hardware and the engine remapping is both physically and diagnostically undetectable.

We change data held on a component of your car, and as we are not changing any hardware on any post-’99 car, we have nothing to give a warranty on. However, we will do our utmost to help anyone who has a problem, including returning the car to standard for testing etc.

Yes it can! We archive your original file, so if you decide to put back to standard to sell, or ….. we can put the original factory file back on for you. To put back to standard, we charge a nominal £100 fee, but we give you a free gift voucher entitling you to £50 discount on your next map.

Once the DPF has been removed, the engine’s management system (ECU) has to have the regeneration process (inbuilt in its memory) removed from it. The ECU remap will also provide you with the full benefits of the power and Torque increase.

As of February 2014, the MoT Test Stations will as part of their VISUAL inspection during the test, check to ensure the existence of the DPF. So technically speaking, until such a time that there is a method to detect soot in the exhaust gases, it is almost an impossible task to detect the removal by any other means than the visual checking to see if the exhaust has been cut and welded! So the answer to the above question is no it will not, but only if they can detect it through the visual inspection of the exhaust. We have to recommend that you look at alternatives, such as cleaning or replacement (and we can offer both at very sensible and much more competitive prices than the dealers). However, should you wish us to, we will remove the DPF for you, once you sign an authorisation letter for us to do so.
