Driver Training

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.
