And, it does it all with stock components, so there’s no additional wiring or hardware to install.Īn ECU flash is undeniably more advanced and streamlined, and generally speaking it costs about $250 to $300 to have a shop perform a flash, which is actually cheaper than buying a Power Commander.

Sure, you’ve got fuel and ignition control, but a flash can also remove speed limits, change when the cooling fan comes on, or keep the throttle plates cracked just a sliver on deceleration so there’s less engine braking, just to name a few things.
They’re going right in there and changing things at the source.Īnd because a flash cracks into the ECU programming, that means there are many more parameters that can be adjusted. With an ECU flash, you’re getting Lasik surgery. The glasses alter the light before it enters your eyes so you can see better. Look at it this way: A piggyback ECU is like wearing glasses to correct your vision. Like Neo controlling the Matrix, "flashing" a bike's ECU rewrites the code that controls the bike's functions.
Basically, the bike’s brain gets fully reprogrammed. With a flash, the code within the stock ECU itself gets rewritten. More recently, the “flash” technique emerged, and FlashTune is by far the biggest name in this field. The Power Commander’s wiring harness plugs into the fuel injectors, throttle position sensor, and other sensors and the module manipulates the signals so that the ECU makes the desired changes to the fuel and ignition curves. “Piggyback” means the unit sits on top of the existing stock hardware, literally. DynoJet's Power Commander is a popular tuning option for a variety of modern EFI motorcycles, from Groms to GSX-Rs.

You also need to tune your fueling to ensure your engine is safe, because if you’re running lean due to changes to the intake or exhaust, you could be at risk of damage.Īs mentioned earlier, to tune a modern EFI bike you either get the ECU flashed, or install a piggyback module like a Power Commander.ĭynoJet's name harkens back to the days when you tuned a bike by swapping out the jets in the carburetor. Because even in stock form, government restrictions, plus liability and reliability concerns from the manufacturer, likely mean your bike isn’t performing as well as it could in, say, a world without speed limits or concerns over greenhouse gasses.Īnd of course if you’ve replaced your exhaust system or installed a high-flow air filter, or done any motor mods like a big bore or cams, then you need to tune your fuel (and perhaps ignition timing) to suit the new setup, or you’re leaving power on the table. What’s the point? More power and improved throttle response, mainly, by way of optimized fuel and ignition curves. With that out of the way, you might be wondering why you would want to “put a tune” on your bike in the first place.
