Enhancing the performance of a vehicle was coined with the the term “Chip Tuning”. It was done in the 80’s and 90’s and involved reading modifying and programming a chip inside the engines ECU (Electronic control unit) called an Eprom (erasable programmable read only memory). The Eprom was removed from the ECU. The eprom code was read, modified and then programmed into a new eprom. You replaced the eprom in the ECU and the cars performance was enhanced
Manufacturers of add on boxes and diesel performance boxes still use the phrase “Chip Tuning” but more about this later – A Remap is not to be confused with this inferior way of adding power to an engine.
At the time, engine control units and the procedure of chip tuning was state of the art cutting edge technology.
It is now old and the technology is prehistoric. Engine technology and its electronic control has jumped light years ahead.
The ECU now contains software that can be read or downloaded onto a computer. The information can be changed in the form of service updates or modified tunes. The information is uploaded or programmed back into the ECU and no parts are changed.
When a vehicle manufacturer programs the engine control unit, very wide tolerances are often used. It uses a kind of one does all program. The dealer has to do this to be very tolerant of those who don’t service their car or maintain it. It is also tolerant of many different countries climates, humidities and altitudes. Fuel grades are also another important consideration.
With all those limitations factored into the cars ECU it is actually compromising the vehicles performance.
A remap from Infinitech still takes many of these factors into consideration and enhances them. Polishing the tune if you like and achieving better results.
A knock on effect you can enjoy from an efficient running engine is improved fuel economy and improved derivability in the form of smoother gear changes and a much more crisp pedal response and acceleration.
Customers who have had their vehicles re-mapped often ask “Why wasn’t this done at the dealer ?”
Performance chip boxes or Diesel performance boxes work in a very different way to a remap. They do give an increase in performance but they work on the principal of more fuel = more power.
They connect between the fuel rail pressure sensor and the manifold pressure sensor and trick the ecu into seing different values than what is actually happening. The ecu then increases the fuel rail pressure which injects more fuel. it stresses the fuel system and offers quite a harsh or on/off style performance.
You can often tell when you are behind this type of modified vehicle by the black smoke it belches out when it accelerates.
They offer no fuel economy and the engine control unit has no redundancy or fault tolerance as it never knows the real values of the fuel system.
It can not adapt to different operating conditions and is by no means comparable to a custom remap.
Your engine will not be over tuned which prevents stressing the engine, transmission, cooling system, ect and so it does not reduce the life span and reliability of the car. This is why it’s so important to choose the best.
Great care is taken to ensure that all of our modifications have no detrimental effect on your car. In a lot of cases the tune actually helps to extend the life of components such as the clutch and gearbox by making the delivery of the power far less aggressive and smoothing the overall drive of the vehicle.
No, in fact its the opposite. Though, if you drive the new tune hard then your fuel consumption will increase. If you continue to drive the car in the same way as you did before the upgrade, your fuel consumption will likely improve.
