Slight RPM Rise?

i think the ecu is just trying to burn off the gas based on ambient temp and humidity along with your last input parameters just before the shift. unless the rpm revs up on its own at a complete standstill (after water temp is at center of gauge) i think it's norma..

I suspect that kenchan is correct. Does it happen when the clutch is partially disengaged or do you have to put the pedal all the way down for it to rev up?

Hey don't make me look bad! We sell a premium product!

Happens when clutch is depressed to the point that it catches or this case, disengages. It's just strange. S-mode does it I know but I even cycled S-mode to make sure I wasn't going crazy. First time owning the car in the super cold months. I will have to see how it behaves in warmer weather.

when you disengage the clutch, maybe roll off your throttle a split second earlier?

I thought so too so I put my foot on the floor and clutched. Still managed to do it. Maybe I'm just going insane!
