I found this article online regarding the 1049 engine and how much everyone loved it, but what caught my eye was the different performance modes you can choose from? Has anyone heard of this and if so do you change the modes with a flash?




D-MODE manages fuel flow. It pulls data from throttle position, throttle valve opening and engine RPM to deliver the correct amount of fuel injection. A user can select from 3 different modes to suit his or her preferences; there is Sport (S) mode, Touring (T) mode and Entry (E) mode. The active mode is displayed on the sled’s LCD display (just to the right of the speed indicator) as one of these three letters.
Sport mode is designed for sporty riding enjoyment, bringing out maximum performance from the engine for a strong and direct feeling of acceleration from low speeds and up. This is going to be very similar to the standard performance mapping that we would be used to.
Touring mode provides smooth power in the low- and mid-ranges, and full enjoyment of the engine’s performance in the high-speed range. Particularly, in the mid-speed range that is important in touring and other longer runs, the engine character is set to provide an enjoyable feel to the ride that reduces fatigue, while also achieving good fuel efficiency. This mode could best be described as being not as jumpy, and “stretching” the throttle response.
Entry mode settings prevent sudden strong responses from the engine, while also limiting vehicle speed in order to ensure comfortable, low-stress touring. It also reduces fuel consumption. Even if you stab the throttle, this mode will keep the engine response smooth and predictable, making it perfect for novice riders. This mode tends to make the throttle feel like it has a rubber-band for a throttle cable instead of a steel cable. The response is mellowed, and top speed is reduced slightly, but not regulated down to 25 or 45 mph like the Ski-Doo ACE 600/900s.
Regardless of the mode selected, the rider will instantly notice a much lighter throttle pull. The mode can not be changed on the fly, only at start up, and the sled will re-start in the mode that it was turned off in.

That feature was only available on the Vectors which used drive by wire. Vipers and Sidewinders still have the cable throttles.
