When a manufacturer
develops a new car they have to take into consideration all of the conditions it
may be subjected to in all of the regions in which they intend to sell this
model. This means instead of just optimising the perfect tuning to deliver the
best performance or the most fuel efficiency they have to make compromises to
the map to take into account these potential differing operating conditions.
These could include sub-standard fuels, extremes in temperature and altitude,
differing emission laws and even the possibility that vehicle may not be
serviced on a regular basis and in accordance with the manufacturers recommended
We at AUTO TUNERS consider all the above extremes in a practical way & adjusting various parameters within the safe limits such as fuel pressure, boost pressure (on turbocharged applications) ignition advance and throttle pedal control amongst others to release the true performance from the engine. It is a completely safe process as it is just giving the engine the performance it should have had in the first place before all the compromises were applied to the original programming. Every engine will have its own unique map and by adjusting this we can fine tune the characteristics of the engine; unleashing more power and in many cases reduce fuel consumption too.
