Tap Shift Lag

[fiatdale]

This has probably been touched on before - but is there a way to reduce the lag of tap to shift time on the 6L80e? There is such a long lag from the time you hit the button to the time it actually shifts. Not sure if you guys can program that to be a lesser time? I know if you're in Drive, you can make the shift quicker, but what about in manual mode?

I don't notice lag when shifting in M on my Yukon. I will check with the guys as to whether or not they can do anything about it, but my gut says no.

So M isn't really manual, it is a maximum. It only permits the transmission to shift to the next gear, it does not dictate it.

Im talking about NNBS - cluster even displays Manual Mode. I think its been disussed how big the lag is from the time you tap up / tap down the button on the column to the time it actually shifts. noticeable 1 second delay. Just wasnt sure if there is anything EFI Live can tweak and make faster.

Even on the NNBS the M is not a true manual mode.

How different is the tuning on the Yukon 8 speed and the corvette stingray 8 speed?
Same transmission. And they are touting it to be one of the fastest shifting auto's in the world... (the stingray version)

 

[JennaBear]

Calibration is the difference. The trucks and SUVs can shift pretty darn fast too.

I'll take that on my autocal please
