I remember I heard somewhere that when in Sport Shift mode, there are certain speeds each gear is used in. Does anyone know the speeds at which each gear can be used??

 

Directly from the manual:

To shift from: Speed Range:
1st -> 2nd - Over 0 mph
2nd -> 3rd - Over 6 mph
3rd -> 4th - Over 20 mph
4th -> 5th - Over 33 mph

2nd -> 1st - Under 31 mph
3rd -> 2nd - Under 69 mph
4th -> 3rd - Under 88 mph
5th -> 4th - Under 131 mph

 

the manual has the listing. personally, i wouldn't use speed as a referance. i think it really depends on what rpm levels you want to shift at. i think most people shift between 2.5-3.0k rpms. i mainly shift at around 2.5-3.5k.

again, this may be just me, but this is what i usually do:
shift : speed
1-2 : around 10
2-3 : around 20
3-4 : around 35
4-5 : around 50

I usually like to shift between 5500 and 7000 rpms!!

 

all the way to 7200 for CAI ~
