But, the most important parameter is to find the proper ignition timing and air/fuel ratio at every rpm. Timing retard is also removed to make engine rev faster. Throttle restrictions are removed and this gives a considerable power gain in lower gears.
With the default factory settings, the ECU is setup for use with balanced performance and fuel economy by remapping the ECU, we can make an engine run more efficiently or create more power by increasing efficiency of the engine. RELATED ARTICLE: Motorcycle Engine Control Unit (ECU) ExplainedĮCU’s chip stores programs as maps that controls the injectors on factors such as how much fuel to supply, when to fire the spark plugs, also monitoring every possible aspect involved in running of an engine. Programming an ECU is removing things like low RPM power restrictions, closed loop fuel maps, errors when upgrading parts and a plenty of other options. The greater the RPM, more the ignition timing would advance. ECU tuning is an art of cracking the factory restrictions and making it better, which is something similar to jail breaking/rooting a Smartphone and enhancing its performance. Just like carburetor tuning, this is not an easy process.
Today, in this modern era where Fuel Injection System has taken over good old Carburetors, the power delivery is managed by Engine Control Unit (ECU) that electronically controls a series of actuators on an internal combustion engine to ensure optimal engine performance. Find your make/model below to see all the features we include with our services.It all started in old grand days when motorcycle engines had carburetors a kick-start to fire up the engine, turning a couple screws gives a noticeable performance gains.
We adjust these settings to unlock the full potential of your engine. Early speed and RPM limiters, reduced acceleration and limited peak power output are all ways the manufacturers have restricted these motorcycles. What does it do? Our reflashing services remove restrictions that the OEM's have programmed to meet government regulations and that reduce throttle response and power output for novice riders. The Read Only part of that means the chip retains its programming without periodic electronic refreshing loss of electrical power doesn't lead to the chip losing its programming (It's like the CMOS BIOS of a computer). "Flashing" the chip involves electronically erasing the read only program and replacing it with new, updated information (the engine control 'map').
The computer "chip" that is the heart of the ECU is usually an EEPROM - an Electronically Erasable Programmable Read Only Memory chip. What is ECU Reflashing? ECU stands for "Engine Control Unit." It is the computer that takes information from the various sensors on the engine like crankshaft RPM, manifold pressure and throttle position to determine how much fuel to deliver through the fuel injectors and when to fire the ignition coils. Allow us to eliminate these restrictions and allow your engine to run the way it should. However, these will limit the full potential of engine for racing use. These restrictions are used to control power output to allow easier control of the motorcycle for street conditions.
