No Lift Shifting

[thekid13]

This is not a repeat thread. I have read some posts explaining how it works and seen some videos. I have some understanding on how it works. But what I would really like to know is what hardware and or software setting(s) is needed to achieve this. Do I need a new tranny? Do I need a ecm upgrade? Do I need other parts? Can this be done to any gen5 camaro/gen6 corvette currently not equipped? Please list all parts I would need including part numbers. Your participation is greatly appreciated!

You can NLS any manual if you are quick enough. The ZL1 feature manages the RPM's through the shift to prevent bouncing the limiter.

and if i was not quick enough how bad would it be to the tranny and or engine? not just once but several times during the life of the car. what device specifically on the zl1 manages the rpm from bouncing the limiter?

If you aren't quick enough it'll bounce on the limiter which temporarily cuts fuel and you'll be slower. It's definitely more stress on the transmission regardless. As for how the ZL1 manages it, I don't have the answer for that.

ECU pulls timing and fuel out in a nano-second, as you hit the clutch pedal sensor tells the ECU to initiate the sequence, to allow you to power shift, less stress on all the parts...keeping you foot floored, keeps the boost pressure up...thus 11.7-9 sec 1/4's.

This is a ZL1 software feature. I wouldn't be doing this in an SS.

Anyone from the Camaro plant know exactly how 'No Lift Shift' works? I know a bunch of you are on this Forum from time to time.

[DavidW]

the specific software that allows it is within the ecm , but it puts extre stress on the transmission and clutch but that cannot be tuned for.

[DESERTDOG]

For sure the transmission and clutch have to absorb the abuse...but a Tremec 6060HD trans will take a tremendous amount of abuse before it fails, and the ZL1 has the duel clutch set-up as the ZR1's...it will wear out sometime, but I'm sure that was all calculated in when GM decided to add this nifty little tech item to the car. Don't know of any other car that has it.

No lift shift is an ECM algorithm design to keep the boost up dusting a shift event. When the throttle is realesed during a normal shift, boost drops and has to be spooled up when the throttle is depressed after the shift. With no lift shift, the accelerator pedal input stays at 100% (aka to the floor) and the ECM holds the engine speed constant during the up shift. This keeps the boost spooled up so there is no lag in power. This feature is specific to the ZL1 due to the supercharged engine. Yes, the ZL1 has upgraded drivetrain components all the way through which can withstand this higher load shifting. There are videos in the Sticky section in the sub-forum.

You will be buying synchro's real quick...

I've datalogged countless hours and everything remains constant during the NLS including fueling, spark timing and boost. There is no drop off at all.

Done properly there is no damage at all. I have been power shifting since the 1960's and have never broken a transmission. Here is a video shot inside my 2004 SRT-10 Ram (which I bought new in 2004). This was shot in Feb, 2013, at Famoso Drag Strip, I remove the seats when I race and put them back on Monday. The truck has an internally pure stock Viper Engine with bolt-ons (headers, TB, exhaust and tune) and it has 67,000 miles and maybe 300 1/4 mile passes. Watch the tach in the video and you will see that it only drops about 1,000 rpm between shifts (I am shifting at 6,000 rpm, my limiter is set at 6,200). No lift shift is the same as a power shift , where I don't let up on the throttle between shifts. Enjoy. The truck runs 11.60's. I love the no lift shift feature, as it was one of the deciding factors in choosing my 2012 CTS V (6 speed manual) over the 2013 Shelby GT500. I have 2 friends who have (had) Shelbys and they said no matter what you do, as soon as you push in the clutch you loose boost. I didn't want that, as I had no experience with a supercharged engine. My first test drive in a CTS V with a manual was great, and the salesman said he had never seen anybody shift like that before. It's a great feature.

We know there's no damage when done right, but he asked what would be the damage if he didn't. missed shift, damaged synchro's.
