Transmission update is available!

[FroggyEclat]

I was treated to 26011 (and a few more) yesterday during the year 2 B service

I guess 26021 is the federal version of ROW 26011....

Latest software upgrades are:
25024 VDDM "Vehicule Dynamics Domain Module"
26003 TEM "Telematics Module"
26011 CPC and TCU "Central Powertrain Control" and "Transmission Control Unit"
26010 DIM all markets except USA "Driver Information Module"

Not sure what they all do.
I hope to find/feel the difference(s) within the next few days of running.

Not sure if placebo, but the downshifts via paddles feel snappier, less delay between input and shift. I feel no decernable difference on upshifts, same slog when not giving it some juice.

Take it for what you will, this was the impressive from a single drive back from the dealership.

Very promising actually! My car is about to get service they will check if it's available and if so I'll report back too

For what is it worth, took more time today to appreciate the software update, the gear changes are definitely quicker. That is both up and down the gears. Strangely feels more responsive in "sport" mode thank in "tour" mode.

 

[hoho]

yep after taking the car out for another drive tonight, I can say more confidently the downshifts are consistently much more responsive to the input. Hilariously, I actually feel like the downshift is more responsive than the upshift now.... lol....?

That and also just installed the JQ mag shifters. so very nice upgrade with both the paddles and the software update.

Call your dealer and ask about 26021 or 26011 and see if its available for your car.

Mine was updated just over a week ago and is definitely better, still not as good as it should be and they haven’t got rid of the stupid double tap to go from forward to reverse but it is definitely better in my opinion

 

[Lotus F1]

Just got my car back. Wow what a difference. I cant imagine the downshifts being any faster. Super crip and immediate. Upshifts felt great too. I think any complaints over the DCT are moot at this point. I need to do a video showing it, car feels amazing

Mine is going in on the 19th, can't wait.

Try all variants of throttle and rpms as you downshift into a corner, I still get the same downshift lag but it's inconsistent - overall better for sure!

I took mine in 6 weeks ago, of course it came out now lol

Just had mine serviced at Lotus of SD. Definitely an improvement from a downshift lag perspective. However the more noticeable improvement is in the way the TCU runs the shifts in auto-mode for all 3 driving modes. The most notable is in Sport mode. It is way more "drivable". No more awkward high rpm shifts at low throttle and on the highway it upshifts into the higher gears based on your cruising speeds. For example, it actually goes into 8th gear on the highway in sport mode. Before, it would never go into 8th gear even if you were just cruising at 85/90 on an open freeway. Now, it looks to see if you are doing spirited driving or just freeway driving and adjust gears accordingly.

Thanks for the feedback. That's exactly what I'm looking for a smoother transition in lower gear in sport (which can get quite jerky at times if you in traffic constantly modulating the throttle).

Have put a couple drives on 26021 and it's definitely an improvement, especially in the downshift. The upshift lag still kinda sucks (still have to anticipate the lag before redline) but ultimately it is a good update. Hope someone will figure out how to tune it further.

26021 software updated was loaded to my car today.
Substantial differences IMO.
Most notable as other have mention is Sport mode. Sport can now be used around town now. Shifts are crisp and if you're driving mildly, from a stop it will shift to 4th rapidly even at 25 mph.
No more awkward holding of gears and yes shift to 8th gear around 75mph.

Now Track mode is distinctly different than sport mode.

Also attempt to reproduce the low speed 1st gear lurching and want able to repo. Tired several times.
Sport is still sporty, hammered it many times; highway and back roads, car woke up immediately. Even after to lugging around in high gears.
Manual shifting seems fine, perhaps better. Although I did have one delayed downshift. However, was making a lot manual inputs for about 5 mins. No other complaints.

I think the Settings UI was also changed, seems like there are a ton of features and graphics, anyone else notice that?

Overall great updates ! just wish I didn't get fleeced on the $780
oil change, that really over the top.

I picked up my i4 on the day of first rain of the season so I did not get a chance to open her up or take it to the mountain and it looks like rain again this weekend. So far sport mode in city traffic is really smooth, no more jerkiness. I think they lower the RPM threshold for up shift, it used to try to stay till 3K rpm before upshift and now it will upshift a few hundred RPM sooner but any pressure on the throttle will bring about a snappy down shft. The move from R to D can now be done with 2 fast click instead of 2 spaced click. Down shift is much faster, probably still not PDK quick but what is? I'll do a more detail write up once I have a chance to open her up and take it to the mountain.

Yeah definitely still no PDK, but it's an improvement to make it on par with most other DCTs.

Try the hold (+) paddle to put into D instead of using the drive selector, saves you time of even having to move your hand down.

UI? New graphics?

Just had my update today 11/11/26. The shifts are smoother and the high rpm hold in sports and track is gone. Maybe it’s me but the difference between modes seems less. Sports and Track mode seems toned down. Track mode throttle inputs seemed brutal prior to the updates. Still fast but less brutal and softer.

 

[Beachbum]

Here's hoping. Mine goes in for another software update and they are loading all of the outstanding ones at the same time.

On a separate, I'll try to find the proper thread later, the P0071 CEL that is caused by the defective Ambient Temp Sensor, has a temporary fix. No idea what it is, at a guess it will just be an update that disables the alert. Whatever it is, it will stop the CEL coming on and me having to worry about it until I get to read/clear it.
