Not sure if this is normal, but after I shut everything off on my 23 F3-T, there is a high pitched whine. Anyone else experienced this?

Thanks Mike!
Yes, it is normal. The ECU keeps the throttle body slightly closed after shutdown. Since it is a 'Fly-by-Wire' system (electric motor actuates the throttle body butterflies). What you hear is that motor whine. I don't remember the time interval. But it does time out after a bit and the whine goes away.
I wonder if it is some sort of calibration procedure?
I misspoke on post #4. The throttle body servo holds the butterflies CLOSED, not open. (edited & fixed)
I believe the startup default setting is 8 degrees open. Which previous, cable controlled Spyders used. The reason BRP did this with all Fly-by-Wire models, I've been told, is that leaving the throttle body open allowed residual fuel vapors to migrate creating a possible explosive mixture. Supposedly, there was a possibility of Run-On or even fire, in extreme cases.
I can't verify the 2nd answer, but the Closed vs Open, that is for sure.
So, my Spyder has been sitting in the garage for 1 hour and 15 minutes, and it’s still making the whining noise.
I was going to suggest that. No really!!!!!:yikes: Glad you have it figured out.
