Introduction:
CRD Technology, a company based in Bolton, Lancashire (UK) have developed an innovative approach to remapping common rail diesel engines. Despite an installation simplicity and physical appearance resembling that of a much less sophisticated diesel tuning box, the Select-A-Map  is a unique, advanced diesel control ECU that enables diesel engines to be remapped, with five user-selectable maps, without reprogramming or tampering with the vehicle’s own engine management system.

Compatible with most common rail diesel engines (including cars, vans and HGVs), this highly universal system forms an elegant solution that can both simplify the remapping of older vehicles and, with its unique non-intrusive method of connection, provide a method of remapping newer vehicles that greatly reduces any risk of invalidating vehicle manufacturer’s warranties.

Select-A-Map Remote Control Key FobThe Select-A-Map ECU revolutionises vehicle remapping. It combines most of the benefits of a conventional 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. It packs a host of other features, such as a key fob remote control (pictured right), giving access to five instantly switchable fuel maps, and the ability to default to a standard or low power map. It even has the ability to control Nitrous Oxide (NOS), via an optional interface using a further 5 fuel maps, or the ability to control the injection of a second fuel, such as Liquefied Petroleum Gas (LPG) or Compressed Natural Gas (CNG) in dual fuel applications.
The only non-intrusive remapping solution
Using patented technology, developed in the UK by the fuel injection experts at CRD Technology, the Select-A-Map ECU allows a vehicle to be remapped without cutting wires or making any modification to the 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 the vehicle manufacturer’s warranty.

Power, speed and accuracy
To maintain engine efficiency and reduce the risk of Diesel Particulate Filter (DPF) 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 its 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.
Additional information for editors:
Select-A-Map Background Information
Select-A-Map was developed to be a dual-fuel controller but also as a solution to address a number of major issues that were identified with traditional common rail diesel ‘tuning boxes’ and remapping technologies:

  • Traditional ECU remapping techniques can invalidate vehicle warranties.
  • Diesel tuning boxes do not provide the accuracy and control of an ECU remap.
  • ECU remapping is becoming increasingly problematic on many newer vehicles.

Select-A-Map’s unique patented technology allows it to measure engine speed and load, which it uses, along with the selected fuel map data, to determine the precise amount of fuel required at any moment. This addresses all of the above issues by providing a non-intrusive means to properly map an engine – with a device that is as simple to install and remove as a tuning box.

Power AND Economy
 
Guaranteed!

The Select-A-Map ECU will match (or better)
ANY diesel tuning box performance!

 
Select-A-Map - Diesel Remap ECU

The Compromise

While it may sometimes be possible to improve on the compromise made by the vehicle manufacturer and achieve a slight increase in both performance and economy, for any real gains, there will always be a trade-off between the two.

No exceptions

  • No single remap can provide the best performance AND economy simultaneously.
  • Running high performance maps continuously will inevitably lead to DPF problems.

This is especially true of diesel tuning boxes, which indiscriminately control fuel, irrespective of engine speed and load, resulting in an even greater compromise that leads to wasted fuel, in the form of particulate emissions, further increasing the likelihood of DPF problems.

Read more about the differences between remaps and diesel tuning boxes here.


 

No Compromise

 
Select-A-Map - Diesel Remap ECU
Highest Performance* Check
Best Economy* Check
Lowest Emissions* Check

A engine remap using the Select-A-Map ECU can out-perform any diesel tuning box in terms of performance, economy AND emissions.

This is possible because, like any conventional fuel remap, Select-A-Map remaps the vehicle's fueling in accordance with engine speed and load but, unlike any conventional remap, Select-A-Map provides FIVE instantly switchable maps (via a remote control).

Each of the 5 maps can be completely customised** and optimised, ensuring that the purpose for which the map is intended, be it performance, economy, or emissions, the best possible results can be achieved, without compromise!

Innovation and Versatility

The Select-A-Map's unique design means that not only can fueling be increased but, where necessary, fueling can just as easily be decreased, all in accordance with engine speed and load. This gives fuel control capabilities that are far more accurate and superior than any tuning box and enables maps to be created that give greater economy, better emissions or that can prevent, or even reverse, DPF blockage.
 

 

Performance Guaranteed

We don't make wild claims or promises about how much extra power the Select-A-Map ECU will give your vehicle – we leave that to the diesel tuning box suppliers – Instead we make one simple guarantee:
 

The Select-A-Map ECU will match (or better)
ANY diesel tuning box performance!

 

We can make this claim because the Select-A-Map diesel control ECU is comparable to a full diesel fuel remap, with which no diesel tuning box can ever compete (more info here).

Additionally, the Select-A-Map provides 5 instantly switchable fuel maps, allowing quick switching between performance and economy modes while driving***, making it a unique, no compromise solution that, unlike any remap or tuning box, is also DPF friendly.



* Compared with a diesel tuning box on the same vehicle and assuming Select-A-Map has been correctly installed, calibrated and configured and that the relevant map has been selected and professionally refined.

** The installer may charge a fee for any additional map refinements.

*** For safety reasons, the engine is required to be at idle speed before map switching will occur.

 

Nitrous Oxide (NOS)

For the ultimate in track day performance that no ECU re-map or Tuning Box can offer. Using the SELECT-A-MAP optional solenoid driver interface, it becomes possible to ‘map’ the Nitrous giving precise control of the solenoid and supplying the correct quantity of Nitrous without waste.

When using Nitrous in petrol engines a lean mixture can cause damage through detonation. By contrast, diesel engines are designed to run lean most of the time, which makes them better suited for use with Nitrous.

Nitrous has a cooling effect and it’s high oxygen content results in a more efficient diesel burn rate that produces more power.

A fast road map will typically take a standard 160bhp engine to 190bhp but by selecting the very fast road map and using it with Nitrous 220bhp is safely achieved.

When the Nitrous switch is armed the SELECT-A-MAP automatically engages the excessively rich Nitrous map and when disarmed it reverts back to the previous selected map.
Fleet Operator SavingsThe SELECT-A-MAP diesel control unit will be of particular interest to fleet users as a simple way of reducing their ever increasing fuel costs. The unit is easily installed and all electronic fuel adjustments remain within the manufacturer’s original engine management system tolerances.The tachometer ‘Green Band’ represents the manufacturer’s optimum engine speed range for both economy and torque.

Operators encourage their drivers to stay within this speed range to save fuel. However, drivers often make excessive use of the ‘Red Zone’ and waste fuel.

Driver trainers are often used to promote sensible driving within the green band, but after a while, in most cases drivers tend to revert to their normal driving style.

The SELECT-A-MAP can be programmed to not only increase torque in the green band but also to limit fuelling in the red zone which encourages a change of driving habits, with earlier gear changes that keep the engine within the green band, resulting in significant fuel savings.

Units can also be individually mapped to suit the operator’s particular requirements.

Acceleration Control Feature

An additional, unique feature is Acceleration Control, that can be used on its own, with a standard map or in combination with a fuel modification map.

It provides a simple method of controlling performance based on engine acceleration rate, allowing acceleration to be limited without reducing torque at slowly increasing or constant engine speeds.

The SELECT-A-MAP positively encourages drivers not to accelerate rapidly and to ensure they stay within the green band, resulting in fuel savings and greater vehicle life.

The SELECT-A-MAP is a universal product that can also be used in many common rail diesel engine applications with custom mapping facility for agricultural, marine use etc.

Diesel-Blend – LPG/CNG

Click here to find out how Select-A-Map can reduce fuel costs and emissions even further when used as a dual-fuel diesel-blend ECU to inject a cheaper, greener fuel such as Liquid Propane Gas (LPG) or Compressed Natural Gas (CNG).

Diesel-Blend – LPG/CNG

 

Diesel-Blend Dual Fuel Demonstration VehicleAnother cost saving option for fleet operators and high mileage diesel users is to run their vehicles on a cheaper fuel blend.

The Select-A-Map ECU was also developed to enable common rail diesel engines to run on a blend of at least 2 fuels, the most common being Liquid Propane Gas (LPG) or Compressed Natural Gas (CNG). It is compatible with most existing makes of LPG or CNG liquid and vapour systems that are designed to operate with multipoint petrol injection vehicles when used in diesel blend applications.

LPG substitution ratios of up to 40% are normal whilst using CNG ratios of above 50% can be substituted on much lower price fuel giving savings of typically between 10-25%.

The SELECT-A-MAP Diesel Blend ECU has many features and benefits not previously available including a choice of maps to suit the type of secondary fuel being used (LPG or CNG) and different operator requirements. Precise control of each fuel via two separate maps allows ethe perfect mixture to be achieved without any increase or decrease in overall engine power.

The Select-A-Map system acts as a universal interface when used with an LPG or CNG gas system, providing the gas system with simulated conventional petrol fuel injection signals that enable any standard gas system to be used in a dual-fuel / diesel-blend application. This unique approach means that the Select-A-Map can be used with virtually any gas system to create a diesel-blend system. Manufacturers of compatible gas systems include (but are not limited to) Prins, Vialle, BRC, OMVL, Zavoli, Eurogas, Bi-Gas, Romano, Tartarini, Landi Renzo, KME, Stefanelli, Necam, Koltech, LPG Tech, Altesa, Stag, E-Gas, Lima, Impco, Mercury, AG, GSPK, XL-R8, Star Gas, Leonardo, Emma-Gas, Bedini, Lovato, Calor, Calorgas, Autogas, Icom, Valtek, Majic, AEB, Stako, GWZM and Pharos.

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. Select-A-Map Remote Control Key Fob

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.
