ECU REFLASH FAQ
Most frequent questions and answers
It is reprogramming the computer code in the ECU (Engine Control Unit) to change the operation of the engine control system. It is called reflashing because the memory where the code is stored is a special type of memory called Flash Memory. The process of reprogramming the Flash Memory is dubbed Reflashing.
The factory programming in the ECU is designed to meet many regulations for emissions, fuel mileage, and noise requirements. These requirements often reduce the overall performance of the engine, and make throttle response sluggish and rough. Improved programming can optimize performance by removing these restrictions, providing an overall better riding experience.
The specifics vary from one ECU to another, but the basics are similar. Most changes include the following.
- Derestriction For Full Power In All Gears
- Speed Limiter Removal
- Raised Rev Limit
- Deceleration Fuel Cut Removal
- Custom Ignition Timing Mapping
- Custom Fuel Mapping
- Derestriction Of The Secondary Throttles Or Throttle-By-Wire System
- Raise/Lower Idle Speed
- Lower Fan Operation Temperature
- Error Code Removal For Exhaust Servo Removal, PAIR Valve Removal, O2 Sensor Removal, EVAP Valve Removal
- Provide The Ability To Change Power Modes And Traction Control Modes “On-The-Fly” and Remember The Power And Traction Settings.
