They have the ability to tune with a CVT clutch to simulate real world load. What makes it different than other dyno's. They are the only specific SXS dyno in the world. They both can load the vehicle for testing in ALL load conditions. We develop these maps on our top of the line Dynojet dyno as well as our Axis dyno specifically designed by for UTV testing. We use the most advance equipment available to build our ecu maps and do a large amount of testing in the field. You need to run 91 OCT or better fuel but the power and reliability is worth it! Also with the better AFR conditions the Viking overall runs much better! It is a win/win. Its is a noticeable gain in power! This is still completely reliable but helps with a better top speed. This flash see's a +5HP increase at the wheels, +8 at the flywheel. We correct the AFR for better engine temp and life in all conditions. For starters, they are extremely LEAN from the factory. We also lower the radiator fan activation temps to keep the engine running cooler overall.Īn ECU Re-flash is a great way to pick up horsepower, drivability and reliability. What your foot is doing will be the same thing the butterflies are! This makes the car drive/feel so much better. We fix all the drive by wire tables and make it close to 1/1.

They will close and not allow full throttle at certain points making the car feel lazy when on throttle. The factory sets them up very lazy and the throttle body butterflies are not pair to the throttle pedal. We extend the annoying speed limiter as well as extend the rev limiter. The engine also will run cooler under the richer AFR conditions. The advanced timing curve is also built to utilize 91+ oct fuel. These are very reliable curves (We specialize in desert racing and we lean on the side of caution when it comes to tuning) In this flash we fix the lean spots in the fuel map the factory has for emissions. We have developed a dyno proven performance ignition timing curve as well as fuel curve specific for the Yamaha Viking. This ECU Re-flash is great for all types of riding/racing.
