When manufacturers develop their ECU’s they must make compromises that take into account the production and operating variations of the vehicle.

No two vehicles are exactly the same due to production tolerances and depending on where and how the vehicles are used they may experience different climatic conditions, fuel quality, service intervals, driving styles etc.

Taking all these factors into account results in a manufacturers pre-set MAP which isn’t optimum for the region of use.

These are less complex than you may have been led to believe. The simple fact is a diesel engine only needs air and fuel to operate.

Given that the air consumption of the engine is governed by mechanical factors i.e. Cylinder head and manifold design, the only adjustments that can be made electronically by chiping are the amount of fuel injected and the point at which fuel is injected.

The electronic tuning of diesel and petrol engines compare in that only the fuel amount and point of ignition are being altered.

The ignition point is determined by the spark plug firing instant in a petrol engine and the point of fuel injection in a diesel engine.

To ensure engine safety, the amount of fuel injected at any particular time is crucial. Too little fuel for a petrol engine and conversely too much for a diesel engine can lead to problems.

In terms of fuel quantity, the optimum power output for a petrol engine always corresponds to a safe fuel amount, however for a diesel engine the optimum power output occurs well beyond the engines safety point.
