Eco Mode - What is this thing actually doing

[askitee]

Has anyone received a genuine explanation of what Eco Mode on an RT Ltd actually does from BRP.

I called customer support which was as about as helpful as asking my 4 yr old granddaughter. Spoke with a dealership and it became very clear he was "assembling an answer" in his head - so I hit him with "do you really know or are you guessing or making **** up?" Reply "guessing!"

Are there any BRP employees on these forums who can explain what it does.

I have found at times it works, and at others turns the fuel consumption to that resembling an afterburner in an F16 fighter jet.

Is it just a Gimmick?

So dear Mr BRP - I know us customers are a right royal pain in the Derrier but can you respond, anyone ??? Being able to use the darn thing in situations that it is designed for would be of great help
