With the advent of modern tools, even the cars have now been made smart and their performance tuning has been made even simpler. Now a days engine tuning may be performed via computers. Car engines may be made better, producing more torque and power and become economical as well as far as fuel consumption is concerned. This all results can be performed by remapping your car's ECU settings.
Now a question arise what actually is ECU remapping?
Before telling you about any of it lets talk about some fundamentals. Different car's performance parameters are now actually judged by sensors embedded at various places in the car. These parameters may include ignition timing, fuel consumption, air flow, throttle position, crank position e.t.c. All these are closely monitored via sensors and their performance reports are send to car's engine management system or electronic control unit (ECU). So ECU basically is a computer software program which process the signals send by the sensors and helps in better performance of the automobile in just about any given condition.
With that said, the question is automatically replied that why you ought to have your ECU remapped. Obviously for better engine performance. The car manufacturers do not always tailor make their ECU settings at sports performance level. It could sound weird for several car enthusiasts but its a fact. The logic behind it is that why would a granny still able to drive or a mother who drives along with her kids, would demand a good performance engine. So that they address the concerns of all the customers and ensure that their product is well enough for almost every conditions.
So ECU remapping can be carried out by just over writing the existing software program of your vehicle and replacing it with a far more tuned software, best fitting your conditions. The remapping, until recently was done by removing the existing chip containing the software. It's been made easy after the advent of serial port remapping, and now ECU remapping may be performed by just plugging and overwriting engine map by way of a better sports performance version into the serial port.
Tuning ECU is really a simple performance upgrading but it might become complicated if you're uninformed of your car's specification and would end up in developing a mess if you may not pay consideration to the conditions, the automobile will need to endure. If you should be a rookie and want to perform a fairly non professional remapping, I would advise you an easy tool best fit because of this purpose. It is called "Galletto" and use to learn your car's ECU chip tuning file. It's available at just about $100 from the internet. You need to get in touch this tool with the obd socket and can be utilized to diagnose any fault in the car. When the information in the ECU tuning file is retrieved you'll need to edit and amend it according to your desire employing a better tuned software program. But be careful here as the information would be in the proper execution of binary numbers. The program programs which are accustomed to edit these information may be either "race 2000" and "winol ".Don't forget to place back tuning file back into the ECU after you are done.
ECU remapping do possess some fuel implications if you're trying to find a growth in engines power and torque. However an car may be tuned to an optimum level to save fuel and improve the power and torque as well. The outcomes of the ECU tuning vary based on the engines on that you performed the remapping.
For a turbo charged petrol engine, you are able to achieve a growth of 20-30% in power and 20-40% in torque. The increase is approximately 10-15% in power and 15-20% in torque if you find a normally aspirated, non turbo petrol engine. Similarly turbo charged diesel engine ECU tuning may yield a consequence of 25-50% and 50-75% rise in power and torque respectively. With all these engine upgrading, high power, more torque and better fuel efficiency, why would you not choose DIY ECU remapping?
