![]() Motorcycles have their own unique "dialect" that is different from manufacturer to manufacturer, and even bike to bike within the same manufacturer. This can take a lot of time and effort and troubleshooting over time, particularly if you do not have a dyno (and I imagine none of us here reading this do).įirst you have to be able to connect and communicate with the bike's computer "language". But the key is LEARNING and experience, and of course having the proper tools to ACCURATELY make INFORMED changes to the base tune to reflect what the bike NEEDS, and not what you THINK it should be. Of course you can! Anyone can do anything they dedicate themselves to learning. 2019+ has some exclusions and weirdness, which I won't get into here. I will not be detailing other years/bikes, but pretty much everything in the same Honda bike family as ours (CBR300r, CB300f, CRF250L, CRF300L, etc) can also be tuned using the same equipment/procedures. Can our bike's ECU's be "tuned"? I've heard it's not possible.Įmphatically, YES! They can be dumped/flashed. You may notice that performance has not increased to your liking it may be that the adjustment needed is out of the range the factory tune can adjust.ģ. If you have, or plan to, extensively modify the intake or exhaust or fueling system of your bike, the factory settings will not be enough to accurately respond to more extreme changes in engine operation these modifications require. The goal is to improve the performance of the bike for it's desired application/use. Some tunes are meant for performance, some are tailored for efficiency, and some are in between. Firstly, common questions to address.Ī 'tune' is simply a modification of the factory software/fuel/ignition reference data installed on your bike from Honda. So without further ado, here are a few common questions I've run into, and some resulting information to help clarify things. YOU ARE RESPONSIBLE FOR DOING YOUR OWN HOMEWORK ANYTHING YOU DO TO YOUR BIKE AND THE RESULTS OF YOUR MODIFICATIONS ARE YOURS 100% IN FULL. ANY ADVICE AND INFORMATION IS GIVEN FREELY AND WITH NO RESPONSIBILITY, WARRANTY, OR GUARANTEE EXPRESSED OR IMPLIED IN ANY WAY, SHAPE OR FORM. I will also include public resources pertaining to Honda motorcycle ECU flashing and factory files that are already public domain.ĭISCLAIMER: I DO NOT CLAIM TO BE AN EXPERT. Potentially this thread could be a sticky preceding anyone choosing to go down this path. ![]() While our bikes are considered antiquated by many at this point, most of these questions and data can be applied to many bikes, past and future. The upcoming tutorial thread will assume that you have read this, so that I do not have to repeat large amounts of information. While we do offer fuel adjustments to match aftermarkets exhaust systems, we believe that you should have control over fuel adjustments with units such as Power Commanders that can be adjusted to match your specific needs.In preparation for my upcoming thread DIY budget ECU tuning/flashing (patience it's a WIP), it would be a good placeholder to have a FAQ post detailing many unanswered questions, uncertainties, and ambiguities surrounding the ability to tune our bike's ECUs. Our a la carte style checkout system allows you to purchase only the options you need. ![]() You are not purchasing a “lifetime” flashing subscription for services you won’t use. How does your service differ from others – 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. "Flashing" the chip involves electronically erasing the read only program and replacing it with new, updated information (the engine control 'map'). 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). 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. ![]()
