Yamaha r1 ecu flash 20134/9/2024 ![]() with a power commander you just need a USB cable but of course can only adjust the fueling (without the ignition module). Requires an ignition cycle to change (so not really "on the fly") and of course can't quickly adjust tuning at the track unless you have a laptop with the $380US hardware/software (it has a new feature called "quick flash" for small changes instead of an entire ecu wipe and reload) vs. With the ECU flash you can wire up a map switch button to switch between two completely different maps (fuel, ignition, throttle, engine braking), so one street one race map, or one 91 fuel map and one and U4.4/MR12. This Danos Performance quickshifter kit (very bottom of the webpage) is plug and play with a flashed ECU: Quick Shifter Switch Street bike? You probably don't need all that. ![]() See post by Pro 6 above.įor my own race bike, I have a canned reflash AND a PowerCommander, because a PowerCommander can't do everything a reflash of the stock ECU can (eliminate decel fuel cut, disable air-suction, change rev limit, and there are certain map functions that a PowerCommander can't do), and a reflash of the stock ECU can't do everything that a PowerCommander can (quick-shifter, and be able to change mapping in 2 minutes at the track if needed). a lot of dyno testing, if you want to get it right. That "different version of software" could be a dealer-initiated service campaign to address whatever issue the OEM turned up, or it could be an aftermarket "canned reflash" that everyone who buys gets the same one to address whatever issue the aftermarket has found a fix for (more below), or it could be a full custom re-calibration done in conjunction with dyno testing. "install a different version of software" = essentially, "reflashing". Not in the "physical object" sense, but a "something that people do" sense. I am not sure what you meant by this, because flashing certainly is "a thing".
