Well after reading this post I had to try it on my ‘24 and it does work. Not at my break-in mileage yet so just tried it at average speed/rpm and sure enough it worked for me. Feels very unnatural though.

I have a 2023 with 1500 miles on her. (Run in service done at 1100 miles). I tried and it worked for me but it’s hard not to take your foot off the gas. Hard enough to untrain my brain not to heel toe on downshifts.

Ye of little faith. I have break in service next week and a full track day the following day. I will send those transmission bits ‘to the moon!’

I tried this on mine quickly, first time it worked (I think), second time didn't. The ride was the whole time in traffic, so there wasn't a real chance to try it out any more...

if it works can you have a buddy take a video from the passenger seat? |

2024 MY here.
Could not duplicate a no-lift shift. Guessing it must be subconscious muscle memory. |

Wow! You guys just about have my eulogy written (Here lies the body of Lester Moore, shot by 6 bullets from a .44…no less, no more…)…
Track day was a blast. No lift shift still seemingly working in my car. I will say at higher RPMs (5k+) it goes up slightly (maybe 100 rpm) with clutch in and then drops down to the next gear’s revs. Mind you I’m not driving it like this all the time, just note it does it. To me it’s just antithetical to driving a manual…will see if one of my daughters will be willing to be my movie-helper tomorrow. Then someone will want a feet video to prove I’m not lifting…sick-o’s!

Takeaways from the track day - If your M2 has brake squeal like mine had (dogs would actually jump and look startled), a track day will cure it. Or at least it has for now. Brakes and traction on this thing are epic. It is a heavy car, compared to any Porsche or Miata. I wish the stock tune had just a little bit more low down grunt that this engine is capable of, but adjusting my shift points to stay revved up more is the answer and not what I was working on yesterday. This is a great do-everything car. Performed very well on track. I thought the Pirelli’s were fantastic tires. There is now a little less Pirelli in the world for the haters out there . Been to the M-School in SC and they felt no different than the Continentals…regardless they worked well. I was surprised by one random thing - no fewer than 4 people looked at my wheels and said “Apex!” How do you like them? Aren’t they great? And they are…2 of the folks with GT3s on Apex rims. Says something to me. They have quite the following on the track, even here in New England. As I was in the “novice” group I had an instructor on board every session (I did seven 20-minute sessions). One instructor has been a PCA instructor for 18 years but had a V8 M3 that he dearly missed (“should have never sold that thing) and drove mine a couple laps to show me the track. Noted it felt “heavy” but was really impressed with cornering grip and commented the manual felt good and was easy to drive. Second instructor has been a spec Miata racer for 7 years. “The entry and cornering speeds on this thing are ridiculous.” After he got used to the speed going into corners we really dialed in braking, entry, opening up the line and braking later, throttling earlier…I have to say the car responded and I felt on another level of driving at the end with him pushing me…did get really wide on a 90 MPH turn one time though as braking point was too late (Mr. Hankey didn’t produce any nuggets). At the end I could keep up with the Z-06 everywhere but the early part of the straights, Couldn’t keep up with the Shelby GT500s or the Tesla Plaid on the straights but would catch up with them in the turns. Couldn’t touch the GT4 or either of the GT3s, those were just quick everywhere (also driven by advanced drivers in the novice group). This car punches above its price range for sure. Go M. Sport seats - I don’t have the carbon buckets. Sport seats held me great, no issues. Interesting how instructors were different….one preferred tighter lines with earlier turn-in (his thoughts - its a very wide track so why use all that extra distance if your tires aren’t asking for it so that is some saved distance/time) whereas the second instructor was all about using every inch of the road (Miata’s need to stay wound up). I made a ton of progress during the day and now understand that 2 extra inches of width on the road on corner out means back to full throttle much earlier. It was a GREAT day, I will definitely be back.

no-lift shift
I've certainly had a few chuckles, grins and a trip down memory lane when seeing this tread...and I know tranny's and electronic systems have come a long way but 57 years ago in my 4-speed 67 Chevelle, I was told I should be able to go faster with "no-lift" shifts.. Up or Down !
and I could slam'em...for some strange reason about a month later, couldn't get the tranny in gear ?? My father came back from the Chevrolet dealership, dropped the gear cluster on my desk, and sternly said, " not sure what your doing, but stop and don't do it again"...needless to say, it came out of my wallet and I have never lost a gear again....Shifter Beware |

This was an open track day, and they had Novice, Intermediate/Advanced, and Motorcycles running 20 minute sessions each hour. Novice group had point-by passing only on 2 straights which was new to me. So the uncertainty of more people, different cars, and open session made it a bit more intimidating for maybe the first 2 sessions. I had also purchased 1 day of Track insurance from Open Track which cost $390 (70K car coverage, 1.5M Liability). Super easy to sign up for.

You can shift it pretty quickly…if gear change assist is on, you just need a quick momentary lift of the gas with clutch-in then back on. That would prevent the little blip up in rpm’s before the computer cuts throttle anyway. So while it’s not really a no lift shift it’s a pretty quickly assisted shift.

It takes the car less than a 10th of a second for the computer to cut the revs once clutch in and it will then match engine revs and transmission speed no matter what - whether you were planning an upshift or downshift…get going in your car to 20-30 mph where you can coast and clutch in and hold it in (foot off of gas), then upshift but don’t clutch out, then downshift and don’t clutch out. It will always match anticipated needed engine speed to transmission speed for the gear you have selected. You will see what I mean. Again gear shift assist needs to be on for this to happen. Then try the same thing with assist off, RPMs will go to idle and will act like a normal manual. You’ll then have to match engine and transmission speed with your foot. Test yours out it what I will say. Absolutely correct this isn’t true no lift shift, but the rev matching can be used to your advantage based on how it works. F80 I had for 7 years would hold revs with gear assist on for 2 seconds, this one hangs there and is IMO a better version of rev matching. That is also what made me think it had no lift shift because it wasn’t overrevving, at lower throttle inputs. It seems these cars are all a bit different. So just try the clutch in thing on a safe road at 20-30 mph and just try different gears holding the clutch in and watch your rpms…the computer is constantly matching engine rpms to transmission speed. No need to trail the throttle in the case of an upshift, it trails for you, and we all know about the autoblip on downshift. Maybe this helps someone understand the car better.

Just get going somewhere safe, clutch in going like 20 mph, no need to go fast. Keep foot off the gas and coast. Watch the rpms. Then downshift and it will blip, then upshift 1 then 2 gears…all while holding the clutch in and foot off the gas. Just see how rpm’s behave when you are coasting with clutch in, no gas and shift 3-4, 4-3 or 2, 3-5…etc. Don’t mean for this part to be condescending but this is how I was taught to think of it: The gas pedal controls your engine RPMs. Your physical speed (wheels turning) dictates the transmission RPMs, always 2 different things. A smooth downshift OR upshift matches those 2 speeds perfectly at clutch out…even on an upshift when you let off gas pedal and clutch-in the engine RPMs have to drop due to inertia of the engine components, compression, and well you just cut fuel…in older non-turbo engines you’d have to trail the throttle on upshift because RPMs would drop very quickly, which is not so important a factor in these cars. Regardless the computer is constantly matching engine and transmission speeds for you for the perfect shift every time. Hope this helps. I’ll just suck it up and shoot a video.

I totally get it, and that’s totally cool. The downshift blip is the only thing I thought it did. This is pretty awesome.
