THERE ARE BIG PERFORMANCE GAINS TO HAD FROM A SIMPLE ENGINE RE-CHIP
ECU remapping is basically finetuning the program that deals with engine performance. As well as producing greater power and torque it also deals with drivability problems at lower rev ranges such as flat spots and hesitation issues giving the engine more initial torque making a more responsive and enjoyable drive. ECU Remaps involves altering the parameters stored within the ECU. This is done by reading the code stored on the ECU, Altering it, and writing it back on. In a very simplistic way, it is the same as updating your iphone with new firmware.
Remapping overwrites the original software contained inside a cars ECU (ENGINE CONTROL UNIT) with tuned software. This software is referred to as the engine map because it is this program that controls the engine. Before the advent of serial port remapping the only way to overwrite this software was to replace the chip that contained the software. Now this can all be done by plugging in to the vechicles serial port and overwrite the engine map with the performance version. Remapping is not a gimmick it is a performance conversion that will seriously improve the power and drivability of your engine.
Remapping an engine ECU will produce an extra 10 - 15 per cent more horsepower depending on exact specification, the engine will also be more responsive on initial acceleration and produce more torque (up to 20 per cent) throughout the entire rev range giving more response with power coming in immediately relative to throttle input. This large increase in power & torque gives far more flexibility in all gears reducing the need to change down unnecessarily to overtake safely and quickly.
