The hot topic in motorcycle performance these days is flashing your ECU. You hear the term “flashing” brought up all the time – and no, we’re not talking about spring break antics, either. But while the term is gaining in popularity, and is often associated with big gains, we wanted to know – what the heck is ECU flashing, anyway? For that, let’s start with a little back story.

If you’re of a certain age, then you might remember the nights spent in the shop, turning wrenches and busting knuckles trying to add more power to your motorcycle. There’s an art, some might even call it a cathartic undertone, to pulling a carburetor and adjusting float levels, changing jets, moving clips, and reading spark plugs. Get it right and it’s certainly rewarding. Get it wrong (which is much more often the case), and you have to pull it all off and try again. It’s annoying and time-consuming, to say the least, and often you walk away greasy, dirty, smelling like gas, and a little pissed off. Odds are you probably lost your 10mm socket, too. All that just to gain five horsepower, if you’re lucky.

Readers of a certain age might not know what these are. Behold, the carburetor. A pretty genius invention, actually.

Despite the romance of it all, the digital age of motorcycling is just…better. Electronic fuel injection is better than the carburetor. Same goes for ride-by-wire throttles. The precision each bit of tech offers is far superior to its analog counterparts. But therein lies the rub; change is hard, and technology can be intimidating to some people. Especially when it comes to making a motorcycle better. Enter the world of ECU flash tuning.
