Just from these modifications, we made an increase +10whp at top end. We unrestricted the factory settings, and only made adjustments to Yamaha's ETV System (Electronic Control Throttle Valve) which is extremely limited from the factory. Here's a dyno sheet of our 2015 Yamaha R1 - BMC Air Filter and 3/4 Cat Delete Toce Exhaust. Here's a great example over why ECU Remapping and eliminating the ECU's factory restrictions is so much more beneficial than Piggy Back Units. Even piggyback systems that have "auto-tune" features are still only hacking the injector signal to reach a targeted AFR. More fuel, less fuel to reach a target AFR (air-to-fuel ratio). When you run a piggyback system, most of them are interfaces that connect between the ECU, and the sensors (typically fuel injectors) to interrupt this programmed signal from the ECU and change it to accommodate for changes the user wants. Significant improvements can be achieved by correcting the stock ECU's deficiencies and tuning the engine to take full advantage of its potential. The result of this is often a compromise resulting in sub-optimal performance. Stock ECU's generally are far from optimal and are developed to allow for a wide range of riding styles, fuel quality and operational conditions. ECU ReFlashing, in general terms, is a method of erasing the ECU’s program code (instructions) and reprogramming the vehicles ECU’s Flash Memory with altered program code, thereby changing how the ECU will respond to inputs. The term “Flash Memory” refers to a particular type of EEPROM that has a fast erase and reprogram time of its internal storage. Most ECU’s have a main memory storage system that is comprised of a nonvolatile Electrically Erasable Programmable Read-Only Memory device called an EEPROM. All of these output responses from the ECU have to be predefined in ECU’s internal memory. In general terms, the ECU is primarily responsible for monitoring and managing the engine's performance via a number of sensors and then calculating the proper signal to send external devices to control the operation of the engine. While it is a customer's decision to use the aftermarket parts, accessories or lubricants, if a modification or the use of aftermarket or unapproved parts, accessories or lubricants can be associated with the need for service or repair, that service or repair may not be covered under warranty.Most modern engines are equipped with a microprocessor-based computer referred to as the Engine Control Unit or Electronic Control Unit which is abbreviated to ECU. We recommend the use of Indian Motorcycle engine oil and lubricants. Mixing oil brands or using non-recommended oil may cause engine damage. Aftermarket modifications to your vehicle can cause poor performance, durability and drivability. The Indian Motorcycle Limited Warranty excludes damages or failures resulting from modified components, the use of aftermarket or unapproved components, or the use of aftermarket or unapproved accessories or lubricants. Aftermarket modifications also can make the vehicle unsafe. These modifications may or may not improve performance, but they can lead to trouble codes, drivability problems and component failures. Indian Motorcycle spends extensive time and resources to ensure that all components, accessories, calibrations and lubricants are tested and validated to provide optimum performance and durability over a wide range of operating conditions.Īftermarket modifications or the use of aftermarket parts, accessories or lubricants are often done in an effort to increase performance or personalize a vehicle.
