I’ve been having all the same problems that you did. So I thought I would go out and try a calibration and see what it did and I’m the same with you. Did the calibration and the car drove totally different after it.
Glad to hear that!
I've had the same experience after calibration. Unusable before and great after. Thank you so much.
Glad to hear that.
12.6.3 was trash for me too. Calibrated the camera’s, went for a drive and it was like night and day. Thanks for posting this video. It restored my hopes for HW3 as well.
WHAT!!! I commented on your last video as I was having the same kind of problems. I’m excited to calibrate my cameras and see if it works the same for me!
This is great to know... I just got updated and thought it was me or I did something in settings...
Will be do a re-calibration with every update from now on... can't hurt.
I'm an IT guy and after an update I restart the car. When I came from 12.5.4 to 12.6.1 I did a camera recalibration and it helped but that version still gave me issues driving around town. But when I recently got 12.6.3 it was a complete 180. It's acting almost like a mini 13.2.x. I really like it and I'm more confident in using it.
Glad you found and shared a solution.
I did in service mode and non luck. Then did it how you did it and it worked!!! Must be a bug in the code as it makes nonsense. Thank you!!
I tried your fix and took my car on a long tough drive. It is performing better than it ever has including pulling into a parking lot and parking straight in. It has never done before.
What king of voodoo Magic is this?
Thank you for fixing my.
And yes of course I Subscribed and hit the liked button.
Old comment I posted on your last video that doesn’t apply any move.
(I have Intel HW3. It is golden on the freeway/highway but lost all confidence in town. It’s bad.
today it even turned into oncoming traffic. Triple stops at stop sings or just stops in the middle of the intersections. I am continually pressing the accelerator.
My wife won’t use it anymore in town).
Thanks for sharing the story! I was wondering what went wrong after watched your previous video. I have the same hw3 with same latest version without any major issues. I am glad you get the issue fixed. Congratulations! I can see how much happier you are now in this video. 😂😂😂
Brilliant idea to recalibrate the cameras! Thanks for sharing that!
Thanks for watching!
Thanks was having similar issues, will definitely calibrate my cameras. !!!!
I'll definitely be trying this too thanks
Thanks Iowa Tesla guy. I’m going out to recalibrate my cameras immediately. WOW What a difference! Sweet!
Hope yours works as well.
@ It did work and it parked at the grocery store for the first time. I did have to do a restart after the calibration was completed because FSD 12.6.3 just went away until I did the restart.
Great job Jim. Excellent PSA for HW3 owners.
Wow, Jim, That was amazing to see it maneuver flawlessly compared to the last video.
Your experience was how I felt two weeks ago when I got to experience V13.2.2.5 that Car was so confident and smooth compared to my V12.5.4.2. I just got V12.6.3 yesterday. I have not had the chance to try it out yet. But I will try it as is to see if the initial experience is similar to your first video, then do the recalibration if necessary.
I did the same thing a few days ago. I cleaned the areas on all my cameras. Did the 2 button reset, and recalibrated the cameras. I made a big difference. I was getting hesitation and stopping long before a turn and it was scary. Now no hesitation and it works great. I agree with your assessment.
I confirmed. I just finished the recalibration and did a test drive. It seemed to improve a lot. For those who did the recalibration and did not have major changes, maybe follow Tesla's recalibration instructions. I cleaned all my cameras, did majority of the recalibration on highway and drove in the middle lane most of the time.
For speed issues, this version still allows you to adjust your speed using the right scroll button. In addition, it will allow you to ask FSD to change lane on the highway when you believe it is better to switch a lane. The previous version doesn't allow this. FSD controlled all the lane changes itself on the highway. This is what I have been wanting. It still gives me some ability to direct FSD which lane is better at what situations. I don't do this a lot, but I now have the ability to ask FSD to do so. Going back to speed control, I found it is very useful that this version gives us back the ability to adjust the speed using the scroll while driving. This is quite useful as sometimes FSD doesn't adjust to speed limit change (e.g. from 90km to 80km and still driving at 90km), I can then manually adjust it to the proper speed.
Entering and exiting highways are very smooth now. My setting is chill and 0% offset. On the chill mode, it will still change lane if it finds the front car is driving too slow, whereas the 12.5.4.2 would just follow the slow car and stayed on the right lane most of the time. I found chill mode is working fine for me already. You can still ask it to change lane to pass a slow car and it will automatically change back once it passed the slow car.
How many miles do you have on your car?
@lashlarue59 you mean the miles I drove to calibrate or my car's total mileage? I only drove about 20km (15 miles approximately) to finish the calibration.
@ No I mean how many do have on your car? I'm trying to figure out how many miles its takes before the cameras need re-calibration.
@lashlarue59 oh, about 28,000km. I calibrated not because of this. I calibrated because Tesla's instructions says sometimes you need to calibrate when there are new software updates.
@@SH-in1qz That's good information, thanks!
Like the improvement.
I was nevervous to update to 6.3 since your last video, thanks for the quick video update, i can now update to 6.3 😊
I have 2020 Model S long range (portrait video screen). The 12.5 has been HORRENDOUS. Almost unsafe by coming to almost complete stops at green light intersections. Constant brake tapping, to point of making me nauseous.
12.6.3 just got sent to my car last night. After reading so many reviews, I've been dreading that nothing was fixed. I'm going to test without calibration, then calibrate, then test again to try to confirm if there was a change also for me and will report back here. Thanks for your videos!
I just want my FSD back from last summer and before. It always drove perfectly. I hate when companies "update" things and make them worse. All too common these days.
So glad to see you resolved your issue! It was bugging me that you had that kind of experience when mine seemed totally different as I was worried that AI3 was starting to fall apart. Happy smooth driving from here on out!
Great to hear it better for you. My worry is that I’ll still have Mario Kart lane changes in rush hour traffic. Sucks in Minneapolis traffic
Great job ! Enjoy the new FSD
Great update! I’m glad things are working out for you now. I shared your story and video on the Tesla Wisconsin Community on Facebook. I don’t have FSD, but am considering doing a calibration after 50K miles just to see if any autopilot issues or other things improve. As you say, it can’t hurt.
Wow that is incredible that it just parked itself! Next time I know to calibrate right after I subscribe to FSD 😂
Makes sense to me. I’m gonna try it! I’ve only calibrated the cameras once when we had a bad repeater camera replaced under warranty at about 35,00 miles. Thanks for the video.
Welcome to the v13 life, Jim! Finally, albeit the "mini v13". It's so good.
It’s definitely usable now.
Great news, Jim! Thanks for updating the Tesla community.
I've watched both videos now. What an education this turned out to be .. at your expense. Thanks for the follow up.
Great Vid. I don't use FSD and have a 2023 Y LR with HW3. Good to hear that there is a fix in case Elon gives us a free month. I was debating getting the new Y because of the HW3 limitations, however will hold off now that you have discovered this calibration trick. Elon should tweet about this as their are a lot of HW 3 owners and he has stated he is not giving us a retrofit for HW4.
It's not coincidence. 12.6.3 was day and night better for me after recalibration. Even though it appeared to fix a litany of problems, I was still wondering if I just had some kind of crazy good luck, until I got home. The acid test that removed any doubt was that I have a 1/4-mile shared driveway. Previous FSD versions would take me home up the shared drive, turning into my individual driveway and stop in front of my garage. As soon as I got 12.6.1, it would no longer navigate the driveway - it would roll a few feet and stop. I would goose the accelerator and it would do the same. That problem remained on 12.6.3. After recalibration, it drove me up the shared drive and all the way to my house.
I usually only watch fsd hw4 v13 videos because i'm not interested in old versions but this is interesting. Like most manufactured things some are great and some are lemons.Glad you turned your lemon into lemonade. I wondered if some cars had chip or cam issues.Tesla should make cam calibration a part of the cars general maintenance
It was on the internet so it must be true lol. Glad it seems to have worked.
damn. 12.6.3 is already great for me but I'm gonna recalibrate anyway to see it gets even better!
12.6.3 is doing mostly good for me. But it has had some issues either getting in the turn lane in time and/or actually turning for the planned route. I might try the recalibration just to see if it helps with those turn lane dramas.
12.6.1 was excellent for me, I had a camera replacement and calibration right when I got it, and now 12.6.3 is awful, I'm having to take over multiple times in a 25 min drive. I wouldn't think I would need to calibrate again this soon, but I'll try it out.
Enjoy your new Tesla!
I have a Model Y and have only used FSD during free trials so far, but I have been favorably impressed with it. Even my wife, who is a constant critic of HSD (husband self driving), loves FSD and is now ready for her own Tesla. I used it to drive 200 miles from my home to the beach on all types of roads, with traffic, and only had to take the wheel once due to phantom braking, apparently because of deep shadows on an open two lane road with no other traffic. I have also used it in the city with good results. My gripes are similar to yours, speed control has been an issue with it going faster than both the limit and my 5mph over comfort level in the city, and 10mph on highways. I think one reason for this is that it does favor matching traffic speed over following the limit, but it rarely goes faster than other cars around it, which you want if you are not strictly obeying the posted speed. Another observation is that it sometimes waits until the last minute to move into an exit or turning lane, though it always seems to do so safely and without being obnoxious. I rate it better here than most human drivers. If I drove more often, I would have signed up for the subscription version of FSD by now, based on how much I like it.
It can be magical and frustrating on the same drive. Thanks for sharing.
Great! If the performance difference is this stark, it would be nice if the car could detect that calibration is needed. I'm really curious what the difference is
Lol I was going to tell you to try this in your previous video but looks like someone else beat me to it.
Effing amazing! LFG! Robotaxi!
Maybe Tesla will start a calibration automatically every time they push a new version. 😅
Amazing job finding this man!
What you did, plus cleaning the part of the windshield that your front camera looks through, are critical to get the best experience.
I didn't clean the windows but the calibration clearly did something positive.
@ For sure cleaning the front camera inside window helped my FSD performance dramatically. Thanks for your vid.
Hey I've also found that Glaco Mirror Coat Zero really works to keep water off the camera lenses on the front fender wells and rear.
There are some YTs out there about it.
Sweet. Good show.
Thanks.
I don’t think it doesn’t hurt to recalibrate the cameras from time to time anyway, but great find. Glad it’s a fixed.
Fixed for now. Hope it sticks.
Good idea, reminds me of scanning for broadcast channels regularly.
@@StormyDog Two different monster. Nice try though.
@@lowhombre explain the difference between the two videos. Just an enormous coincidence from your view is what you are saying it sounds. So why does the car behave very differently from one day to the next?
@ Did he do anything different? Oh, yes he did.
There needs to be a reason to recalibrate your camera. For those rare cases it will make a difference.
Thanks for sharing this? Side question: what are those shims between the glass roof and top of the headliner?
Did you have problems with crossing the center line on tight left hand curves or crossing thr fog line on tight right hand turns on country roads
Very Good Video, -- Could you briefly explain the Camera Calibration Process?
I'm going to try this. I've disabled FSD because of the speed control issues. There's hope it seems!
Worth a shot.
@iowatesla I just installed 12.6.3 yesterday from 12.5.4.2, but the roads were snow covered so I haven't tried it yet.
Definitely trying this. I’ve put 80k miles on my MY and the last 5-6 fsd updates have been bad for me
It was clear that it helped me.
Even if hardware 3 doesn't happen it doesn't really matter that much. We should be getting free hardware upgrade
..... and then there's me still on 12.5.4.2 😕
Crazy that this info isn’t being communicated by Tesla
Anyone have experience with FSD while having two bikes on a trailer mounted bike rack? I tested it recently with two bikes - which were covered - and it was unusable. I wonder if the recalibration at the start of a long trip with bikes would make a difference? Thanks in advance. MY HW4, FSD v13.2.2
Can you test smart summon? May be why mine errors out so often!
Great idea! I will need to do that.
Just recalibrated, no appreciable improvement.
It's particularly bad at crowding the center on unmarked streets, same as it did a year or 2 ago. 😢
Sorry it didn't work for you.
@ I had such high hopes!
2019 Model 3 - just for reference
Perhaps have Tesla check your camera alignment.
@@StormyDog Not sure that would yield anything. Everything has been fine, I'm confident that the next release will fix it.
@ Upon further review, I only recalibrated the forward cams, I went back and included the others. I need to do another drive, but that may be the issue. I’ll let you know.
I wouldn't heap so much praise on Tesla without first conducting more tests, 1 test does not signal success
It was 1 video. I’ve tested it a number of times off camera.
@@iowatesla In that case, well done and t hank you for sharing.
