The OEMs spend thousands of hours on ECU calibration. It takes someone who really knows what they are doing a lot of time, including a lot of real world on the road testing, to sort this out properly. This involves actually editing the control program that is on the bike’s standard ECU and then uploading it to the memory. Same goes for off-the-shelf PowerCommander maps. This brings us to the second method for fuelling tuning: re-flashing your ECU. Errors and unknowns and uncertainties and production tolerances won't matter so much. ECU Flashing is the process of updating the software that runs on your bikes ECU. My experience has been that the "canned" tunes are somewhat rich, because tuning on the rich side is more forgiving. So chances are, if you have a relatively common bike, with relatively minor common stuff done to it, and you are not racing or doing fuel-economy contests with it where the last little bit of fine tuning starts to matter, a "canned" off the shelf tune will be just fine without any further dyno optimizing. Camshafts, cam timing, big-bore, forced induction, major reconfigurations of intake runner geometry are real engine modifications that will require custom tuning. My Z1000 became far more enjoyable to ride after an ECU flash. This ensures that the ECU is always running the most recent software, which. Motorcycle manufacturers typically recommend that the ECU be flashed, or updated with new software, every time the bike’s engine is serviced. If you want a faster bike, buy something else. A motorcycle’s ECU, or engine control unit, is responsible for managing the engine’s ignition timing and fuel injection. Turning a couple of screws on the carburetor resulted in significant performance improvements. If anything, the fuel economy will get worse. Thinking of getting an ECU reflash Here are the pros and cons Motorcycle engines had carburetors and utilized a kick-starter to fire up several decades ago, before the emergence of modern-day electronics. There will not be a detectable difference to power or fuel economy. And how fussy you are.īear in mind that a stock air filter or a K&N air filter or an Amsoil air filter or air filter won't make any meaningful difference, and a Hindle slip-on muffler or an Akrapovic slip-on muffler or a slip-on muffler also won't be worth a hill of beans. spongebobmeth R6, 250SX, WR450F, RM125, 1 yr. ![]() The red line is what’s called Stage 1, with just an ECU flash on an otherwise stock bike. It is very crucial to know how to flash ECU to ensure the maximum performance of your bike. The blue line is the baseline run with the completely stock bike. Because your ECU controls so many components of your motorcycle’s engine, when you flash your engine control unit, many components of the sensors will be tweaked. depends on how common your bike is (with whatever you've done to it). ECU flash can either be a program flash or a data flash. I’m sure someone will chime in with the US cost shortly.įor me, on my ‘16 F3-L it eliminated throttle lag (which the pedal commander also now does), but also made it a much smoother, more responsive power progression.Whether you need to dyno or not. It then has to be reflashed….this is very rare. The quick flash works well unless you take your Spyder to a dealer and they reset your ECM for some reason. You can either take your Spyder to the shop and they can flash it in situ, or you can remove it from the Spyder and post it to your shop where they can either do a quick flash, or they can take it apart and do a permanent flash. ![]() It is performed by specialist tuning shops (CanAm Spyder specialists. It will NOT be done by your dealer….they frown on it (toeing the company line….not that your motor will blow up) nor can you do it at home. ![]() Not answering your questions in order, Bill ….
