Diesel tuning in general is much more straightforward. More fuel equals
more power.#dieseltuning #chiptuning
Diesel chip tuning boxes and diesel tuning in general create more power by
increasing the amount of fuel injected into the engine.
However when the fuel is injected into the engine it needs to be done correctly to
avoid excessive fuel consumption and to prolong engine life.
And this is what sets the skilled tuners and the professional tuning box
manufacturers apart from crowd.
Generally speaking diesel chip tuning boxes reduce fuel pressure when the car is at a
constant speed and increase fuel pressure when the car is accelerating. This
gives the best of both worlds, reduced fuel consumption and increased power.
Skilled tuners and professional chip tuning box manufacturers will know
when
and by how much
to increase fuel pressure to get the maximum amount of
power while at the same time making sure engine temperatures stay within safe
limits.
This knowledge comes from experience and testing. The larger the range of
products a company offers, the more resources they need to have to be able to
test their programs on each engine.
How can these companies be sure their products do not cause excessive engine
wear?
Again, it comes from being able to test their products. Not only testing for
power but also monitoring the EGT temperatures with the new program. While more
fuel equals more power on a diesel engine, more fuel also means more engine
heat.
The correct tune needs to strike the correct balance between power and engine
(EGT) temperatures.
The problems with tuning box companies publishing power figures
Human nature means people will always want the diesel tuning box that gives the most
power. This makes it hard for quality products to stand out from the crowd. An
experienced tuner or chip tuning box manufacturer may know they can get more
power out of an engine but they also know that to get that power EGT
temperatures will be high and will shorten the life of the engine/turbo.
To get around this issue, chip tuning boxes can make their products adjustable.
With an adjustable tuning box the manufacturer can supply the boxes with a safe
tune but it also gives the customer the ability to increase the power themselves
if they want.
Summary
Diesel tuning involves getting more fuel into the engine.
Improving fuel consumption and at the same time increasing power is done by
lowering fuel pressure when the car is travelling at a steady speed and
increasing fuel pressure when the car is accelerating.
The diesel tuning boxes with the highest quoted power increases are not necessarily the
best. There must be a balance between power and engine temperatures. More power
is great but it means higher combustion temperatures, if the temperatures are
too high, the life of engine components can be reduced.
Adjustable tuning boxes allow the chip tuning box manufacturer to supply a safe
power level but also allows the customers to increase the power level (but the
customer needs to be aware of the downsides of increasing the power above the
standard settings).
