![]() That tends to leave fuelling on the lean side of the equation and is the reason a lot of bikes leave the factory with flatspots around 3-4k rpm.īikes run cooler with more fuel. Everybody started somewhere, and I've met a lot of "professional" hacks in my days.Īny number of reasons, manufacturers get it wrong and release bikes with issues (choppy, jerky low speed throttle response especially the transition from closed throttle is probably the commonest,) that can be resolved with different maps and eliminating emissions driven features like fuel cutoff, the fact that bikes aren´t necessarily tuned from the factory for optimum running, there is normally a (big) compromise to get the bikes through the emissions/noise tests to guarantee compliance with the market they are trying to sell the bikes in. You know: Build a connector to connect to the COM terminals of the ECU, incorporate a power supply to this harness, download "this" software (even if I have to pay for it), open software, connect to ECU, etc.Īlso, please don't tell me something is "best left to a professional". I understand the theory of ECU tuning, I want to know specifically how to do it. I started getting better hits when I tried DIY ECU flash. The piggyback tuners can only screw with the injector signal.Īnd I know how to use Google (boolean search and what not). You get way more tuning parameters too, like everything I've seen in these Flash your ECU websites like turning off decel fuel cut or bypassing o2 sensors, etc. Now they've gone to a CANbus USB type that goes right onto the ECU port in the wiring harness and allows you to tune from an app on your phone. In the 00's and early teens the tuners were the piggyback style that would alter the pulse width and duration of the injector signal to give more fuel. Not sure I'll ever see that though.Ĭlick to expand.Actually tuning in the Harley world went in the opposite direction. I dream of the day we will shove a usb stick (like flashing a tv) in a connector and it will load a csv file containing the mappings (or write back out why it was rejected, like non-monotonic or unsafe values). with a steep entry cost I think, unless the info I found is old style. So, doing it yourself is an admirable idea. The investment is high for the seller and the return takes time. So essentially the client pay for data to be installed and the research time. Considering that the cost of an ecu component is 200+ it is a not a good offer to provide one to clients. ![]() The mapping becomes a precious secret practically copyrighted. There is much tuning and you can guess there is a lot dyno time for a top quality map. Every throttle position (a collection of ranges) and rpms (another collection of ranges) maps to an injector opened-closed cycle, iirc. The other side of it, the one trying to make a business of it, is not designing a mapping out of guesswork. (I'm not advertising, it's just a search result) Chances are that in the future maybe a good soul will write opensource for it, but the cost of the physical interface will likely jump up, because there is money to make from flashing ecus. There are various types of motorcycle ecu tools, micro ecu tools, and diagnostic tools depending on the needs of the users.It involves some equipment obviously to connect to the physical interface with a computer, and a software which is likely not free either.
