Enhances maximum torque with the aid of a high-performance exhaust like an Akrapovic Evolution Titanium Full System Exhaust – Titanium With Carbon Fiber Cap (view on Amazon).Maximizes thermal efficiency and makes a 25–30% increase in power output possible.Benefits of an ECU FlashĪrguably, remapping or flashing an ECU is believed to give a vehicle or motorcycle that “instant punch” or lift in power output and performance. Best of all, no wire cutting or splicing is required (although this last bit is still contingent on the complexity of the module’s design). They clip onto existing motorcycle wiring harnesses and sometimes come with software that enables module programming at home. These modules can be ordered online and are delivered pre-programmed to your doorstep. On the other hand, owners who prefer convenience would go for plug-and-play Dynojet Power Commander V 15-027 (view on Amazon) and the like, which practically yields the same results. They believe that flashing is not only the sole means to fully bend a vehicle or motorcycle’s ECU to a rider’s will but also the only way to access and tinker with the unit’s throttle map. Those more comfortable with driving hundreds of miles to visit a tuning shop replete with a dynamometer and an in-house remapping savant would naturally attest to an ECU flash as the route to go. It modifies these signals according to how a rider would want these instructions to be interpreted by the engine. It sits alongside the ECU and hijacks input and output signals from the sensors to the ECU to the power mill. I can only speculate the reason behind the confusion, as an ECU flash and the use of a module or other piggyback unit are two entirely different things.įor the most part, ECU flashing does not require any extraneous tool to remap the ECU, alter numerical values, and change programmed instructions apart from a scanner or software reader.Ĭonversely, a module – more popularly known as a Power Commander – is an external component in itself. When it comes to tweaking the ECU, these two are often confused with each other. These calibration variables are only referred to by the ECU software when needed. A program flash is remapping or flashing the area responsible for controlling logic and where the entire software code resides.Ī data flash deals with the area where variables like constants, curves, and maps reside. There are two segments to ECU flashing: program flash and data flash. An ECU flash allows the alteration of various maps and settings in the stock ECU, significantly improving engine performance. But because they are far from optimal (partly due to gatekeeping certain performance facets), they need to be tuned to correct factory-setting deficiencies and bring out the full potential of a vehicle or motorcycle. In stock form, ECUs are configured to monitor different aspects of the engine and allow for a wide range of operational conditions and riding styles. The process is usually paired with other performance-enhancing mods such as chassis bracing, installing braided brake lines, and upgrading suspension components. What Is ECU Flashing?ĮCU flashing, by definition (Foreign Affairs Motorsports), is a procedure that “ updates the software that runs your vehicle by changing or modifying the vehicle’s memory chip in the ECU.” Simplified, it is a term that refers to updating your ECU software or flash memory with altered program codes so that your vehicle or motorcycle runs smoothly and more in tune with your riding style (and other requirements). Moreover, it is not a procedure to be performed without considerations – details of which will be in today’s article. However, it is not a Band-aid fix to engine or drivetrain damage resulting from the use of substandard fuel, vehicle abuse, or driver neglect. It also removes OEM-programmed restrictions in the ECU, impeding optimal power output and throttle responsiveness.ĮCU flashing is a sound solution for resolving engine problems and optimizing performance. Thankfully, ECU flashing is a thing – something that we will learn more about in this guide.Īn ECU flash is a procedure that alters or remaps the read-only part of your ECU chip or EEPROM (Electronically Erasable Programmable Read Only Memory). And while there is good reason behind this setup (safety of beginner riders, for instance), stock settings undeniably limit the optimal performance of the vehicle or bike in question. Vehicle and motorcycle owners know too well that factory settings – be it air-fuel mixture or speed rating – are always conservative.
