Remove all speed and gear based restrictions We will give your bike an additional 15-18 rear wheel horsepower and remove all throttle and timing restrictions on the bike from the factory that US model YZF-R1 models have. We can return the ECU to stock if needed, free of charge. This is the same ECU flash we use on our championship-winning YZF-R1 race bikes. We will make sure that every ECU is right for each rider. We are offering a service we feel is superior to any of our competitors and with unparalleled support. You send us your ECU and we reflash it to your custom specifications. This includes but is not limited to: Throttle mapping, torque curve mapping, ignition mapping, fuel mapping, engine braking strategies and many other aspects of the ECU. This is the same mapping that has led our team and sponsored riders to multiple race wins and championships! What sets our service apart from others and why we have such a solid reputation in this industry is that we do all of our mapping and tuning in house. Please don't hesitate to call us at 82 (M-F 9-5 EST) if you have any questions for us about ECU flashing, or any other product.
