Analogue - Digital. Do you know the difference?

All Power Box modules contain a digital microprocessor. This 'chip' intercepts the fuelling signals being sent from the ECU to the fuel pump and digitises the signal (i.e. converts it to a number). It then uses this converted value to 'look up' the new output signal value from the pre-programmed fuel map inside the Power Box, which is based on the half and full throttle fuel map from the original ECU. The optimised output value is then converted back to an analogue signal, which is then fed in real-time to the pump. All analogue boxes on the other hand contain primative electronics which manipulate the control signals by multiplying the analogue signal by a certain analogue value. The digital method can thus be tailored exactly to meet the engines requirements at all rpms throughout the rev range. The analogue unit's are hit & miss throughout the whole rev range and cause uneven and poor delivery of power and torque. View the analogue/digital fuel map graph below for further information.

Digital Diesel Tuning
Is accomplished by means of a modern RISC microprocessor with an extremely high degree of accuracy. On the basis of a manufactures standard fuel map the intelligently programmed management of the diesel performance chip tuning powerbox control unit sends the modified data to the injection pump, which then meters the exact diesel quantity for extra performance.	Digital Benefits · Easy to install. No adjustments necessary. · Always an optimum calculated increase of the diesel fuel injection quantity together with the function of the factory set fuel injection map. · Optimum utilisation of the engines reserve capacity from the manufacturer (15 - 25 % power and torque increase) with minimum smoke emission and minimum engine stress. Digital Drawbacks · None known

Analogue Diesel Tuning
Is accomplished, as a rule, via a manually adjustable 1, 2 or 3 potentiometers, primitively designed minimal electronics in a plastic box. These devices have no engine or vehicle specific fuel map, but are equipped only with a basic electronics that manipulates the control signals sent to the injection pump. 1 or 2 potentiometers are used to adjust the power increase in the lower and/or upper speed range the third potentiometer is used to influence the overall setting and the smoke emission	Analogue Benefits · None known Analogue Drawbacks · Labour intensive and time consuming, as the adjustment must be carried out while driving. Manual and therefore inaccurate adjustment. · Too high an injection quantity in certain sub ranges (heavy acceleration) leading to increased fuel consumption and smoke emission and then to thermal engine damage. · Almost always requires extensive readjustment.

(R)evolutionary Intelligent Diesel Tuning
The graph (highly simplified) illustrates the difference between Analogue and Digital diesel tuning. · The green area over the standard fuel map represents the optimised range of the diesel performance chip tuning powerbox control unit · The red area represents the manually and hence inaccurately adjusted range of the analogue additional box. The graph clearly shows the superiority of the digital diesel performance chip tuning powerbox unit over the analogue diesel boxes and their much higher efficiency due to the fact they do not stress the engine and therefore do not reduce the lifetime of the engine. Analogue diesel boxes cannot be optimally adjusted throughout the total range. They are usually adjusted too rich in sub ranges. The engines consume too much fuel and emit un-burnt diesel resulting in large clouds of black smoke while accelerating.
