I didn't think the current Tremec manual transmissions could detect any gear except reverse. If that is still the case then NLS and Rev Matching would require some way for the ECM to know that you are shifting. That may require engaging the clutch to use NLS and RM.

Yeah I don't think it's too complicated. Tie the clutch switch to the ECM, every time the clutch is pressed the ECM knows it and holds the RPMs. It's not gear or speed dependent. Any gear, any RPM, any ground speed. Clutch switch position changes, ECM holds the engine RPM.

Right, you need FI for no-lift because a carbureted engine has no electronic fuel management. Fuel injected engines all have throttle position sensors which actuate the fuel injectors.

Sorry, when I said FI I meant forced induction, the opposite of NA, naturally aspirated. I guess I thought that would have been clear from context when I said "boost" but, mea culpa. Plus fuel injection is often referred to as EFI. Oh well, updated with clarification.

The ECM holds the engine RPM in place when you hit the clutch. Plain and simple. Eliminates the need for you to lift off the gas when you shift. In a car without no-lift shift, when you push the clutch in while holding the gas pedal down your RPMs will zoom up and probably bounce the rev limiter, as the engine is under load while the clutch is engaged in whichever gear, but as soon as the clutch is depressed the engine is in neutral so to speak, and will rev up without load. That's why, when you shift a manual, you let off on the gas while you push the clutch in. Those who've mastered this can shift a manual as smooth or smoother than any automatic transmission in the world. Those who can't get the herky-jerkies.

No-lift essentially lets you cheat, and will turn anyone who isn't a master of shifting into Mario Andretti. All you have to do is keep the gas pedal floored, clutch in and shift at any RPM you want, and the ECM does everything else for you so the RMPs stay and the clutch re-engages smoothly.

Not sure where everyone is getting this bost, NA, DI/non-DI nonsense from. No lift could be incorporated into any car with fuel injection and a throttle position sensor and an ECM. A 1988 Z28 with TPI could have no-lift.

Oh, sorry, yeah I guess I'm showing my age lol..... and mechanical fuel injection is still very popular at the drag strip. Constant flow fuel injection, no electronics involved at all.

It was common to power shift our muscle cars when drag racing. WOT, stab the clutch and shift. No let up on the WOT. Be very quick and do not miss the shift/gear. No rev limiter then.

Like rev matching, it seems the computer is now tending the store to assure no over rev. or limiter hits.

Basically, rev-matching is controlling the RPM while the clutch is pressed, regardless of the throttle pedal position - exactly what no-lift-shift would do.

I would be confident to bet that no-lift-shift will be included with the rev-matching feature.
What you are saying makes sense, but wouldn't they advertise no-lift-shift if it was available? From the beginning, they mentioned Active Rev Matching feature, but I've never seen No Lift Shift being mentioned any where.

I think Nissan 370Z was the first mass produced car with active rev matching, but I don't think they have no lift shift.

If Gen6 comes with no-lift-shift, Great! If not, I can still live without it.

I wonder, did GM do much advertisement for it on the 5th gen ZL1 ?

I finally had a chance to take a look at the video, does the ATS-V do rev matching or was Randy heel-toe'ing it?

As someone who isn't that great at driving a manual yet, I hope the Camaro does have it. Anything to help the transition from driving auto to stick would be great. Then I can turn em off as necessary to get the quintessential manual driving experience.

It should be new to you - Nissan only created the technology a few years ago, where it premiered in the 370Z.

Discussion about no-lift shift on the ZL1 in the above video around the 1:36 mark.
Keep in mind that the no-lift shift feature only functions at WOT.

When it's done correctly, it really snaps your head back!

Best regards,

Elie
