How does it in any way affect the way your spirited driving? Since you are shifting by lifting off the gas pedal it's completely deactivated which is the old school way of doing it so I can't even remotely think of how this is an issue. Maybe check out the section on skip-shift. |

Perhaps it takes a fraction of a second for the NLS feature to realize that a driver is running the engine above the threshold for NLS to work but is making a lift-foot upshift anyway. That could hold the revs up momentarily rather than letting them drop back immediately. I'd imagine that there could be some variation in how much/how long it takes to drop out of NLS.

I think Norm Peterson got it. It just hangs enough for me to hear it and feel it. This is my first 4 cylinder turbo also used to the v8 rpm seems to drop quicker on those. But thanks for everyones input I will let her break in a bit for awhile and see what happens.

I'm kind of thinking NLS might be even nicer when the RPM doesn't drop as fast. I will add once you get used to it when going WOT it comes totally natural. |

I thought maybe he was hitting the clutch pedal a little early causing the rpm to cut.

turbos often have bad rev hang. That's what it is, not NLS. Rev hang.

That's right. The rev-hang has more to do with emissions control of not allowing the throttle to snap closed suddenly. Has nothing to do with NLS

If it was, I didn't see it either (and "Drives: Chevy Camaro" under the avatar pic isn't enough information either).
As mentioned, turbocharged cars do have some reputation for rev hang. But it's hard to say under what conditions it'll be worse and when it won't be as bad. On our new WRX, rev hang is horrible on the 1-2 if you're hurrying it at all. But almost completely absent if you aren't, and unnoticeable between other gears under . . . let's call it "moderate enthusiasm" using maybe 80% of redline and shifting carefully but reasonably quickly. On re-reading Midblue's original thoughts it also occurs to me that if NLS was calibrated more for the straight line crowd it's not going to suit the corner-carvers - or those who drive less "brutally" - nearly as well. When the revs are intentionally held higher than the next gear requires, you gain a brief acceleration spike as flywheel inertia converts to additional driveline torque as it decelerates to the rpm that matches road speed. This spike is also what helps you chirp the tires on a harsh upshift. But it isn't particularly useful at autocross or out on the big tracks where smoothness is the preferred quality and where reducing shift time to some absolute minimum normally isn't all that important.

Almost certainly 5000rpm - same as the '17-'18.

Thanks everyone for the replies. Question for 2.0 turbo drivers, now that I have changed oil I am getting on it a little more and tried this NLS so my question is when I do it very smooth sifts no power loss but turbo seems to make a fart noise like an exhaust brake on a truck,is this normal for 2.0 drivers? Sorry so many questions new to NLS and turbos learning as I go.
