![]() ![]() Even my mechanic buddy remarked that it sounded like it was idling and running healthier after I got it tuned. His tune fixed a lot of the quirks and qualms that I had with a factory tuned 2021, and has made it an overall pleasure to ride. I highly doubt anything will happen to the bike, and like I said, your service department will most likely not care, especially if you make the job of submitting the claim easy by not making modifications apparent.Īnd seriously, Dave/VCycleNut is the best in the business. You're more than likely going to be fine, especially if you get in good with your local service department. Places like my local dealer, they're just like you and I, looking to eek out what they can for a little more fun, and they won't say $hit to Yamaha, especially if in regards to Point 2, there is no giveaway that something on the bike has been tweaked. An 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). If its a super by the book dealer, they most likely will. ![]() Still in regards to the warranty, its also partially up to the dealer if they decide to tell Yamaha the ECU has been flashed.He actually bought the ECU that Ivan used as his test mule to develop the tune. Redneck J had been talking with Ivan for some time now and had his reflashed a few weeks ago. Yamaha corporate won't be tipped off to a ecu flash from pictures With the press of a button, it will flash your motorcycle’s ECU. I recently had my ECU reflashed by Ivans Performance Products. As Dave said, you may need to erase his signature off the ECU case if they want pics of the ECU for whatever reason, but that is pretty easy all things considered. If you have a power commander, that is pretty difficult to hide (service manager's comment). The ECU is the brain behind your motorcycle’s engine, managing and optimizing the engine’s functions. ![]() If you have a warranty issue, Yamaha may want photos of the bike to approve the warranty case.In fact, for the pending recall fixes, any plugging in for the recall flash should in theory just overwrite, no questions asked (outside of the "Are you sure you want to do this?" Unlike on cars, where a flash counter exists in the ECU, and the ECU is read by the dealer and corporate, Yamaha can't jack into your ECU and see it was flashed, tampered with, etc.Our reliable, high quality ECU re-mapping service starts from just £350 +VAT.So, I had a discussion with my local dealer recently after an unsightly issue I'd rather not think about again (nothing related to Yamaha's build quality, or anything Dave at VCycleNute did), and one of the service guys took my (shameless plug here) VCycleNut tuned 21 MT09 around the block (Hi from Colorado my friend! Been meaning to send my impressions of the tune but have been slammed with work and its been a bit on the cold side) and the topic came up in conversation about the tune and warranty. It’s also possible to unlock additional features and capabilities of the ECU – for example, on the latest Kawasaki ZX10r we can enable the auto-blip function, adjust RPM limiters, adjust fan temp, and adjust RPM idle, to name just a few. Its primary purpose is to improve rideability. The benefits of ECU flashing aren’t necessarily about headline-grabbing power gains but rather achieving a smoother, more responsive power delivery throughout the rev range. Thus overwriting the chip with a new program is known as flashing, re-flashing, or direct ECU mapping. An ECU chip uses ‘flash memory’, a type of solid state software encoding. There is still a case to be made for taking that path, as a fuel module can be easily removed, returning your bike to a completely stock condition.īut as an alternative it is now possible to directly re-program an ECU chip. Previously the only way to alter these settings was to use a piggy-back fuel module, such as a Power Commander. The real-world consequences of these compromises are experienced in things like snatchy throttle pick-up and flat spots at certain points in the rev range factors that directly affect rideability. Ultimately, this program determines how your engine operates.īut the manufacturer’s program contains a number of compromises and limitations, both for engine reliability and more often to fulfil emissions test and other regulatory requirements at certain RPM values. The ECU is factory pre-programmed to manage a wide range of parameters. Without reflashing, the data stream from an aftermarket computer that the other components in. In other words, flashing an ECM allows it to have the same software and parameters that it would have were it in a vehicle rolling new off the assembly line. All modern engines are controlled by a microprocessor chip the Electronic Control Unit or ECU. Reflashing allows the engine to be tuned calibrated in the same way that the factory does it. ![]()
