 |
||||||
The world's most advanced diesel performance computer |
||||||
| The SELECT-A-MAP Diesel Control ECU is a new generation, diesel control computer that is undoubtedly the most sophisticated and advanced tuning product available anywhere. | ||||||
|
||||||
A complete fuel remap with all the convenience of a tuning box |
||||||
 The Select-A-Map ECU is quite simply a revolution in vehicle remapping. It combines most of the benefits of a conventional diesel ECU remap with the ease of installation of a diesel tuning box. It is designed to be highly universal, making it compatible with most common rail diesel engines and it contains a host of other features not found in any other product.
The only non-intrusive remapping solutionUsing patented technology, developed in the UK by the fuel injection experts at CRD Technology, the Select-A-Map ECU allows your vehicle to be remapped without cutting wires or making any modification to your vehicle's ECU. This not only makes for a quicker installation time, but also makes transferring to another vehicle possible and greatly reduces the risk of invalidating your vehicle's warranty. |

Power, speed and accuracy |
||||||
| To maintain engine efficiency and reduce the risk of Diesel Particulate Filter blockage, it is imperative that any modifications to the quantity of fuel injected are precisely metered and timed. The Select-A-Map ECU achieves this by accurately monitoring fuel rail pressure as well as injector opening times, using a unique, non-intrusive injector sensing method. It performs many millions of calculations per second, enabling it to compute engine speed and load values instantly so that the exact quantity of fuel required is always injected at exactly the right moment. | ||||||
Advanced Features |
||||||
| Using the same principle as a professional ECU re-map to create a mirror image of the vehicle's own ECU fuel map, the SELECT-A-MAP creates 5 different maps that are instantly switchable using the remote key fob with the ignition on or engine at idle. |  |
|||||
1) Standard Map |
||||||
| Standard torque and standard power. | ||||||
2) Economy Map |
||||||
| Increased torque and standard BHP to enable optimum economy – Can be refined to operator's specific requirements. | ||||||
3) Fast Road Map |
||||||
| Increased torque and increased BHP for everyday driving, while retaining good driveability and improved economy, with no adverse effect on DPF. | ||||||
4) Very Fast Road Map |
||||||
| Tuned to give the highest Torque and highest Power for occasional fast road or track day use. Note: Prolonged use of this map could result in more frequent DPF regeneration and, since it provides uncompromising levels of performance, fuel consumption will likely increase. |
||||||
5) Reduced Power Map |
||||||
| Low Power or 'Valet' option enables already powerful cars to be used by less experienced drivers. | ||||||
|
Any of the predefined maps can be used as is or, as an optional extra service, the installer can further refine any map* to suit individual requirements. No single map is right for every purpose. Vehicle manufacturers are forced to compromise by producing a map that meets emission regulations while providing acceptable economy and performance. ECU re-map specialists experience similar problems when working with a single map; improvements can be made in some areas but never in all areas. By offering 5 customised, instantly switchable maps, it is possible to provide an uncompromising solution that can be tailored to suit any purpose and every customer. Some re-mapping companies offer customers an optional OBD handset that allows switching between 2 maps, but this procedure can take several minutes to perform and carries a risk that a data error could render the vehicle's ECU inoperable. A specific map can be selected as the default map to revert to at power-up/ignition-on. For example, it may be preferable to always start the vehicle with a standard/100% map or, for added security, a reduced-power or ‘valet mode’ map. Note: One exception to this is Map 5 which, when selected, remains selected, regardless of any default map settings or ignition status, until a different map selection is made. * Additional mapping costs may be charged. |
