TOYOTA / BMW, FIX THIS!!! TC/ESC Issues on MK5 Supra.
Вставка
- Опубліковано 14 лип 2024
- The MK5 Supra was such a hyped car and it was supposed to be a rebirth of a legend. From it's unveiling everyone was trolling it for being "just a BMW Z4". Which was not necessary a bad thing. But then the real problems came up: OEM alignment issues, bump steer and to add to the list of dangers: ESC/TC that lives its own life. The chassis has so much potential, yet here we are...

I see everyone commenting about TC not being able to be switched off/car go into sport mode due to too low tyre pressures. This is indeed the case and is the case on F series BMWs. However! With "right" TPMS, the TC/ESP will switch back on randomly anyway. Which is... dangerous.
If you have removed the adaptive dampers and they have not been coded out, this will also cause the car to pull you back from the sportiest modes as it thinks there is something wrong with your dampers. Usually that will give you a chassis stabilization warning though, which I did not see on your dash. Just a friendly heads up!
There are also other reasons for this issue as I hinted in the video of TwistedSymmetry - sometimes it's the EDC and/or the lower ride height after a suspension modification:
www.supramkv.com/threads/electronics-affecting-traction-control.2993/#post-62936
BTW: It's not only affecting the TCS but all the VSC as you have already noticed.
Put it in dynomode maybe? That's what I did with my old E63 AMG and it worked..
Could be totally off here, but could the pre-collision avoidance be in play here? Heading high speed towards a wall and it's applying the brakes on its own?
@@SingleSpeed427 Nope. First it works only up to 53 mph. Secondly you'll see a warning light before anything happens, then dramatic warning lights and you'll hear a buzzer. Seen here:

Car: "Tyre pressure low. Stop carefully"
Misha: "You have no power here!"
Car: *engaging ESC*
Lol - I was just looking at that - it doesn't seem to me that Mischa is obeying and stopping carefully.
Misha: I guess you won't be needing your ABS then

I guess that's Karma for making fun of George in yesterday's video (the lap before).
Psh, was going to comment exactly that. Get out of my head, Misha! But holy hell, that's bad. Why does it keep turning off as soon as you drive off, surely that's not how it's supposed to behave, according to the manual or something?
Terrific 2021 Moment -1
Hehe, atleast u get it now!
That was some scary stuff indeed!
Glad your skills saved you from doing anything radical!
ask that friend from yesterday to show you the middle finger too, and the balance in the universe will be restored.

As long as this tire pressure warning is active it will continue to happen, the car "thinks" it has low tire pressure.
good point...
He said at the end that it also happened with stock tire pressures. I think if this would be the issue, it would not let you turn it off in the first place as long as the tire pressure warning is on.
@@nirfz I also read a test from German motor journalists and they also had issues with the traction control interfering harshly on the racetrack, although it was turned off. Their car was 100% stock and they didn't have a tire pressure warning light on while testing.
@@Chris675R Sounds like the Sport Auto ESP to ESP OFF Comparisson... I read that too. :-)
@@nirfz Yes, that's it, thanks I forgot where I read it.
Misha, I had the same issues with my m140i, since the most of the control units are the same, here is why: as soon as the car feels that the tire pressure is dangerously low, it kind of sends the TC unit in leap mode. Therefore you get the mistake on the dash which says that you can drive but slowly... On my m140i i couldnt even switch to Sport mode or Sport +
pretty much exactly what I was going to say!
Yes, the same issue was one the M2 🤦🏻♂️
So, this is actually an issue from BMW?
I had the same issue with m140
I ended up with m2 geo, bilstien b14 kit, lsd, m4 control arms, poly bushing and under body brace. Finally it handles.
@@RDSAlphard YEAP : )
I really enjoy this format of the video with 3 cameras. Hope to see more videos like that in the future! Keep on the good work.
Very interesting to see the difference between racers and _car enthusiasts_ . You actually test what the car claims it can do vs. driving quickly on public roads and giggling.
Love the work you do! 🤜🤛
Makes you wanna move to nurburg and own 47 cars
Customer - "TC OFF"
Toyota - "It's just a prank, Bro." 😅
not Toyota... it's BMW dressed as Toyota...
I wonder if the new Z4 m40i suffers from the same issue! Would be interesting to know from what part of the project the issue comes from
I've got a Z4 sDrive30i 2019 with all options ticked, and it does not suffer of these issues. Sure its not the M40i and it handles a bit better, but still very close.
If you put it in DSC Off or Sport Plus (Fun mode with a little slip), it will never turn it on again unless you shutdown the car.
To Misha; instead of screaming at Toyota to fix their shit, maybe sort out the car first. TPMS sensors are nothing in value compared to what the car is worth, just buy them. If you've removed the adaptive suspension, then do it properly and code it out.
Your videos are usually entertaining, but this one was more of a joke...
I have a Z4 m40i and i tried this, didnt turn back on thankfully
@@falsterboo as they say in the end they are not the only ones and also they had the same issue when it was stock and other people have issues with it being stock as well
@@advocatesdevil7064 apparently, there's 15 other fanboy's that missed that detail.
Also, to my understanding, having the option to completely switch off something, only to see it coming back by itself it's already a massive fail!
your telling me this isnt the z4? have i been lied to
You are very brave to drive this that quick knowing this 😂 great video Misha.
well done, amazing lines you have while racing man. And good info on the supra
Anyways, that was impressive to see you drive when you are motivated to make your point. Usually we see a relaxed Misha that is going fast, but we just saw a super fast concentrated Misha and that was great! Obviously it would have been better without the scary moments! Be careful!!!
I can't wait to see the video where you explain the moda you did to fix the bump steer.
I learn a lot on this videos! Exellence driving!
My 6th gen Camaro ZL1 had an issue with one of the TPMS sensors, and would do the same thing. Wouldn't let me put it into Race mode, caused the ABS/ESC to act weird. It's not just a BMW/Toyota thing, modern cars have too many electronic nannies for their own good sometimes.
hahaha I love your use of the symbol while swearing. This must have been so disappointing. Glad you didn't go off the track there! It's really scary to watch the car slide out of control frame by frame when the ESC/TC kicks in.
Misha finds out the colour of adrenaline is brown 🤣
How did you get the track next to your name? Asking for a friend...

You should talk to Jackie Ding he had the same issue on his time attack supra. Pretty sure he got it figured out.
Toyota: We can't afford to develop a new platform for the Supra, so we're going to partner with BMW and you're getting a Z4 in a dress.
Also Toyota: Here's an entirely bespoke loss leading homologation special we developed to go rallying.
That we will not and can't use in wrc any way :)
They wouldn't be able to use many bespoke Supra parts on other cars but that is possible with the GR Yaris, for example there are rumors of a Corolla getting the same engine which means that the development cost of the engine can be paid off with different models instead of just selling one car with a high margin. This would not be possible if Toyota made a 6 cylinder because they don't make other cars where it fits, along with many other parts. The same goes the other way, Toyota were able to use many parts bin parts from other models (I belive the rear suspension is from a Corolla) while making the GR Yaris. Toyota has a special way of making cars which increases the reliability but it also requires sharing parts between models since each part takes longer to develop and because of that it's more expensive. Because of these reasons they would have to sell the Supra for a whole lot more if they made it themselves and noone would buy it. This is why it was possible for them to make the GR Yaris but not the Supra
The gr yaris' cost is basicly covered by the Gazoo Racing team (toyota factory racing team)
@@migueldenboer5186 Toyota owns them so it's still Toyotas money, it's kinda like saying that Porsches GT division paid for the GT3
@@ericsson_motorsports OMG your so smart. No, at first hand it comes from toyota but the sponsorships and marketing that is on the racing cars pays for the costs
Here before BMW Supra comments and George and Tristan)
god I like that:. Thanks Tristan!
Good to see someone actually reporting issues on the supra, everyone in the US is raving about the a90 supra and its awesomeness...
Maybe it's because of the tyre pressure warning?
Edit: maybe that's the reason it keeps popping the tc on again
Yup, had the same with my M135i
Can you see the full video before commenting pls? 🤦♂️🤦♂️🤦♂️
@@nunovicente34 yeah I have watched, maybe reseting the tyre pressure monitoring on the dash doing this the warning should go off because you "told" the car thats the normal operating pressure, I should have written this on the comment tho...
@@GiovanniGamer345 he asked if you have watched the whole video, because Misha said at the end that he had the same issue running normal tyre pressure, and they experienced the same issues when the car was stock with the adaptive dampers still fitted. So it's definitely nothing to do with the tyre pressure warning.
@@JamesBalazs yeah but I assure you that he didn't do the reset on the dash that's the main issue I think
It's kicking in more than on my C2 VTS from 2007.... WAUW
Traction mode is not traction control off (at least on bmw's) you need to hold traction control button longer to turn it completely off. Fix TPMS system, it disables sport suspension etc. If you don't have sensors, you can code it to passive mode.
Ive have a similar issue with a much older Toyota. I had a 2005 Celica T Sport where you could turn off the TC but not the ESP and on a few occasions half way through a corner it would think its sliding and severely brake a wheel to correct an imaginary slide, had a few scares because of it!
Commented on George’s video also - it’s the ride height sensor/adaptive suspension.
his face while going out of the Karussell represents the whole video
Je rijdt echt ziek goed man.
Get definedcoding to code GTS into your sports+ mode. It’ll get more slip angle without intervention (traction light)
The very first car, I ever drove, with TCS, was a 1998 SS Camaro.(new at the time), I was pretty well versed in slides, and control. I expected it to slide, in the corner I put it in. .... I knew this was coming. TCS engaged and I almost took out a row of mailboxes on the inside of the corner. Cars these days, are too smart for their own good, or ours one.
Lil late, but the last video I watched of nurburgring highlights there was a supra early in the video with a BMW. You could visually see the supra dancing trying to hang onto the BMW. Was scary and puts a great perspective on this video.
Unplug the yaw sensor and do a proxy alignment and it removes the TC from the car permanently. you can also turn tpms off in the body computer via obd2
It definitely has the hallmarks of the car sensing something it's not happy with and resetting but bizarre that it doesn't let you turn it back off without restarting the ignition though 🤷♂️
It is because of tyre pressure warning. I had the same with my M135i
The "NOPE" at 4:17! Hilarious :D
Lol thats exactly what I noticed when coaching in a Supra and I didn't know what to think of it back then
4:40 "Tire pressure low. Stop carefully."
Misha, who went past Antoniusbuche going 208 km/h:
*_N O_*
*Antoniusbuche - Antonius beech :)
@@schumifannreins295 thanks for the correction
It's the tire pressure monitoring system doing that.
We have 3 BMW 235/240s that all freak out if you drive with the tire pressures low. Aka, cold pressures for track driving.
Same here in the 2021. I had to do an alignment to correct the passenger rear wheel (LHD). It was toe out.
Good that you are an experienced driver. Sad traction control a problem. You deserve , car not so much.
As per owner's manual, there are a few criteria that will lead TC/VSC to come back on automatically. A flat tyre is one.
Misha probably best way to see if it’s just a “Toyota” issue could be to take a Z4M40i for a lap and see how that does when driving the ring with TC of as they’re “the same car” but the bmw doesn’t seem to suffer from the traction issue
Misha, as a modern BMW owner I would love to know more about this Low pressure/ TPMS problem and what solutions there are to be able to drive wour modern BMW on track
Get OBD plug with adaptation capability and change ESC settings from there. Works on VAG/AUDI, BMW has its own versions.
I believe it keeps turning on because the tire pressure. My father has a new bmw and when driving it with low tire pressure the car will automatically turn on traction control when driving. It also becomes extremely sensitive with the traction control when going over 130kmh.
I own and frequently track my 2021 Supra (40+ days so far); fortunately this issue hasn’t happened to me. I do have the tire pressure warning (i run 25/6 cold and 32-5psi hot); but the tc/vsc wont kick back in when running.
i am not getting the chassis warning as the car is stock.
Not sure why this is the case for me; car has a late 2021 ecu. Just putting a datapoint here.
Thanks always Misha for the great content!
It’s an enthusiastic car Misha and when you wanna drive fast on track, you have to keep it off to have more fun. It’s disappointing Misha just like the Launch Control.
Misha, I think Audi's traction control is also the same in a way that you turn off the traction control but when you drive it fast around a track, it kinda cuts power even if it shows that it's off on the instrument cluster.
As an Audi S3 owner, I've had no issues with ESC "full-off" (long hold). I can do donuts in the snow and it will stay off and give me every bit of throttle I ask for. This is on stock ECU/TCU tune (until warranty runs out :P).
The only issue I've had is the Haldex bias changing mid-corner as the front and rear gain and lose traction.
Never heard any Audi’s doing that.
Hi Misha, hope you will see my comment. I had exactly same scary moment years ago on a spirited canyon run in my infiniti g35 coupe after having new rear tires installed. TC got involved heavily in a fast right sweeper, applied brakes to front left and I ended up in oncoming lane almost losing control. Took me a while to figure it out, and here is the issue: infiniti used wrong tire sizes for their staggered set up , just like Toyota did. 225/45 front 245/45 rear, should be 255/40 rear, Toyota is using 255/35 front 275/35 rear, should be 285/30 rear. This makes front and rear tires rotate at different speeds, fronts always rotate faster, which is negligible in regular driving, but in extreme conditions, and in my case new rear tires and 50% tread left on the front, the circumference of the rear tires even longer, the outside front tire was rotating so much faster in the corners that TC was thinking that it was slipping and applied braking to it. Problem went away after replacing front with fresh matching rubber. Bmw was always using correct tire sizes for staggered setup, like 225/40 front, 255/35 rear, 245/40 front, 275/35 rear, and so on. So if you calculate the thickness of the sidewall it's always about the same, the circumference will be about same, so will be the rotating speed.
I see your TPMS sensor light is on. You have to get that fixed in order for traction control to turn off.
You will also need the rsr cancelers to get rid of the chassis error. This will also interfere with traction control
But that's a really stupid (and dangerous) feature, linking the tire pressure warning to the traction control.
Didn't they expect that people would drive a sports car on the track?
I can drive my car on the track right out of the box with lowered tire pressure (it also has TPMS), no tire pressure warning and no traction or stability control interference at all.
With a sporty car like that and it's price tag that should also be the case with the Supra.
@@Chris675R exactly
@@Chris675R I think quite the opposite - a car with one low tyre - for example - will be very unpredictable and therefore the safest thing to do is to ensure nannies are on. This has been a feature since E and F Series BMW's.
I am also almost certain that the DSC (as BMW refers to it) is integrated with the ICM (Integrated Chassis Management). Why not test with road pressures and then as tires warm up and pressures increase you release pressure - obviously as a test - as it won't be feasible for Misha's use case...
@@Diebaas407 In my case, the recommended tire pressure by the manufacturer is 2.6bar cold (front and rear).
On the street I drive with 2.3bar cold (Michelin Cup2). On the racetrack 2.3bar hot (Nankang AR-1) which is like 1.7-1.9bar cold, depending on ambient temperature.
The car is still stable and predictable with that low cold tire pressure with the semi slick tires, so I cannot confirm your argument.
Also for a luxury sedan like the 7 series such a safety feature might be a good thing, but not with a sports car like the Supra. On the racetrack you start with a low cold pressure, but the tires warm up and the pressure rises, like the example with my car above.
There shouldn't be a tire pressure warning on a sports oriented car, when running only 0.3-0.5 bar lower than the recommended pressure by the manufacturer. But that seems to be the case with the Supra. Because the hot pressure with semi slicks is not that far apart, from the recommended cold tire pressure from the manufacturer.
They should have thought about that, before throwing the car on the market. I don't have any issues regarding that whole matter with my car, so other manufacturers/models took that into consideration.
@@Chris675R That totally makes sense - sadly the enthusiasts who like to drive and drive enthusiastically on a track with these cars are in the minority based on the sales volumes.
My example was more related to a car with one underinflated tyre and not a car with 4 equally low pressures - this will destabilise the car, under braking, cornering and acceleration - so these systems are designed for road driving and not track driving, and therefore will keep the systems on if it detects and issue with pressures.
I have in the past - with underinflated tyres performed a reset in the iDrive menu and it goes away - keep in mind once tyre temps increase - and therefore pressures too - and if you perform a reset - it should clear itself.
BMW also incorporates two systems - there is TPMS and Run Flat Indicators - they do the same thing but the former works with actual pressure sensors and the latter uses DSC (ABS Sensors) to determine rotational speed to detect a flat tyre.
BMW's are VERY sensitive to tyres, can't tell you why - but that's been my experience with the numerous BMW's I have owned. :-)
Misha I believe the supra has a mode wherein sport + can be unlocked. It can be done by using a bmwcoder. Just not sure if it fixes the TC issue.
I press LIKE not because you nearly crashed Misha but because I like the time and effort putting into making this video!
It's kinda annoying that most BMW M car owners especially M5 & M8 owners didn't notice such problem otherwise, it would have been popular all over the internet Misha.
04:17 I had to do a double-take when ‘NOPE’ appeared, then it dawned one me it was your edit 😂😂😂. Perhaps Toyota could add that when owners attempt to switch off VSC?
1:15 was when the VSC turn back on, for no reason.
4:17 too, just moment after you turn it off.
My supra doesnt show this behavior, if I remember it correctly. But I will test it tomorrow.
Only due to tire inflation warning. I had similar issue on Dijon’s track but after inflate a bit thé car was clean.
Just add a resistor to the TPMS sensor to trick it. The fault was caused by a low tire pressure causing the TCS on limp MODE. Vertical and lateral load when corning the TPMS sends data to the TCS module. Rule of thumb when playing around with electronics don't mess with the main control module, just trick it to think everything is fine. 😂😎😅🤣
There are many dangerous things in driving fast but nothing like unexpected and out of driver's control things
I felt this one. Thats some final destination shit, that is.
Oh go look for jackie ding channel. There development on the Supra is top notch. They did run into issues with damper removal and tcs.
Randy Pobst talked about why some car companies have bump steer: racecar drivers really like to have the back end kick out. Porsche changed this mentality/drivers a few years ago. That's why 911 GT cars these days are "easy" to drive
Do you have a link ?
It’s in one of the Vinwiki episodes with Randy. Sorry if I don’t remember exactly. It’s one where he talks about working for a manufacturer
idk if it actually works because it didn't seem to when you tried it at the end of your drive but if you're right and you can keep it disabled by holding down the button maybe it can be wired to a switch which will emulate you keeping your finger on the button
good electrician can solve all those problems I was dealing with a lot of similar problems in cars you can install modules in place of every car sensor that will simulate work of the sensor abs sensors will always have correct reading even if you are in the slide its only a electrical signal you can event make it think its standing still not driving at all when going 200km/h
Misha, I just relate to you so much. I love that you captioned your rant. It's hard to balance being angry in the moment, and startled, and then come back down. I got cut off by a dump truck last week, and the younger me would have gotten enraged and been angry for a while. I was like, "WTF?!" but then quickly realized, he probably didn't see me, also, he's trying to work, and I personally feel if someone is working on the roads, I try and give them priority, whether it's a builder work truck, or an actual driving for a living truck (UPS, DHL, FedEx, etc). Anyhow, point is, I appreciate your "in the moment" thoughts, but also your retrospective view when editing.
I'm happy that my car doesn't even have traction control. However it also doesn't have ABS which is kind of scary sometimes.
🤣
PHD racing Supra also had the same issues with tc randomly turning on
Misha: I drove a lotus Evora with low tire pressure... and the car turned on traction control the same way. The car was outrageous to drive. It actually hopped the equivalent of two lanes around the carousel at Sonoma Raceway and scared the crap out of the car owner. I was not scared but frustrated.
We added tire pressure (which then was not ideal) but the traction control did not intervene again.
Turning on traction control is a safety issue that was poorly implemented...
some silky driving that lad.
I had the same problem, and was scary
I suspect that, by design, the TC / VSC is not actually ever completely disabled, even when it is "turned off" using the available controls.
And this ladies and gentlemen is why I don't want to buy a car made after like 2008
Misha, I think this has to do with the tire inflation warning. On my F30, if the car thinks the pressure is too low, it will let you select the sport mode when stationary, once it is moving it goes back to comfort and won't let you change it - similar to the start of your video. I guess it is a safety feature for the BMWs...
And what if you don't have tire pressure sensors?
@@ziomel105 then you have system based on wheel speed rotation, and you simply need to initialize it.
@@thecat.noregret which you can reset and still drive without tc with no pressure in tires.
@@thecat.noregret I was talking about situation of putting a wheels without TPMS on car with TPMS
@湾外国人 As you can see by the error message on the dash, it assumes tyre pressure loss.
This is what keeps me from driving new cars, i’d rather drive one of my bmw e36’s which i know of when i press the esc butten it will turn off all help systems and i’ll be good to go😎
Thanks 🙏 you made it safe out of thar crazy TC malfunction!😜👍great driver can in most cases! Have a drink 🥃 of that present 🎁 that we gave you!!! It will help😃😀😂
Good video
Good comment
find the ESP fuse in the fuse panel and pull it out. If that works, wire up a dash mounted ESP on/off switch. On my VW that wont kill the ABS but ESP cant interfere anymore. Maybe try that because what happened to you is downright dangerous.
Ryan Tureck got some sort of the same problem trying to drift the mk5. There was something going on with the tc.
none of these problems with my sierra 👌
At the fastest track in North America (Mosport), which is 45 minutes East & North of Toronto Canada, I can put my 997.mk1.GT3 in a situation where the ABS goes into Icemode as you are at max braking going into turn 5a. If you do not release the brakes, something your mind does not want to do, as it crests the hill, you will go off the track at 5b - with 100% certainty. In a Cupcar, with the Motorsport ABS unit, you can carry far more speed in and take the brakes all the way to 5b. You just have to drive around it - it's insane - it can kill you.
I just found this video in sight of trying to find out if anyone is having this issue. I have a 2020 Supra that “Did not” have this issue until recently. I’m stock suspension with just a down pipe and JB4. This almost ran me off the highway, i was going 80mph on a highway with a slight turn and traction control kicked in forcing me into the wrong lane. It felt as if i was severely under steering. I’ve since had my alignment done and new front tires with still the same issue. I’ve tracked this car at least once prior to me having this issue and suddenly became an issue for the past week
would be nice to see the Z4 in comparison.
misha... maybe it has to do with the tire inflation error with the aftermarket tires? The esp has a different calibration depending on tire pressure. Maybe thats it. You tested with the stock tires?
nice viedeo
Super !
This thing is rocking like a kayak in a boat wake through the corners. Its just stabbing at the power.
Overtaking was okay Misha, you knew the guy, his indicator was on. It was only a bit off the Apex LOL 😆
But fine
Another Reason to but the Proto Z/400Z if it’s everything NISSAN says it is, and most NISSAN TC/VDC issues can be fixed with an unplug of a sensor, module or fuse. On NISSAN cars enabled with VDC/TC hitting the VDC (Vehicle Dynamic Control or Stability Control) button only turns off Traction Control (Straight Line Traction), the car will still fight you around corners unless you either put in a switch for the module or snip the power wire for it completely. Then of course the car freaks out when you flip it and VDC won’t cut back until you cycle the ignition again.
Can you reprogram the ECU to remove/permanently disable traction control?
Even if your tire pressure is low or not set to factory you should still be able to disable it.
I’m wonder if your tsc issues may be corrected so long as the vehicle doesn’t “thinks” your tires aren’t ie tpms. A lot of times there are built in safety related programing. I’d look to see if it can be coded out and have ftms which only looks at wheel differential speed difference. With ftms you can run it at any pressure. Another thing I’d try is to go into I drive and reset tpms if you haven’t already.
Scary issue indeed. A colleague of mine did a TPMS faker hobby project for his Kia Ceed. He used a devkit with a radio-equipped microcontroller board.
First he figured out how the factory TPMS sensors communicate over the air, then the simply recorded the radio messages of the wheels and the device replayed the packets forever.
I guess there are aftermarket faker devices for sale onthe net as well, for the different brands of vehicles.
Isn't that a solution for this issue?
Jackie Ding has a Time Attack A90 which is fast as fuck and he doesn't seem to have any issues I wonder what he has done.
Tuning, likely. But for guys buying these and trying to keep warranty, that's not a great solution.
JD had alot of troubles the first season, look at his display and you'll see all sorts of warning lights, and messages going off. I do believe they tuned it or did a thing that ignores it.
He has a massive rear wing creating down force for days, helping keeping the rear planted. Watch the lap at Circuit of America where the wing comes loose. The car is ridiculously out of shape.
He had a lot of issues if you watch his videos
there is a time attack racer on youtube that races the supra named Jackie Ding with PhD racing. i bet if you could somehow contact them they could help you out a lot with performance issues. they have had tons of issues they had to overcome to get the car to win at Time Attack
Don't apologize, drive like you stole a car!🤣❤👌
I can't imagine now more fluidly/smoothly you could drive that car. It gives me an impression you have to constantly wrestle the car around. Constantly correct with the steering wheel. I don't think you ever needed to correct the car so many times - correct me (not car /s) if I'm wrong,
Also, H/T to George the Twisted Symmetry, for best description of this issue, check it out in previous vid @11:00 (or 10:59, however you like it), though!
Put it in dynomode maybe? That's what I did with my old E63 AMG and it worked...
I wondered about this too.
love that it says "M Sport" in the centre of the tachometer, definitely not a BMW tho...
Apart from the on-off problems: Do i understand that correct: when it kicked in, in the corner it made you understeer towards the outside barrier? Isn't that the opposite of what ESC should do in that situation? I accidently managed to make the ESC in my car (much older car and from a different manufacturer) think, i would be too fast for a corner twice on a pulic road and both times it did the exact opposite, of what you had in the Supra: it felt like it breaked the inside rear wheel and pulled me into the corner. (it avoided understeer!)
I know that most toyota/lexus cars when u press the trac button once , the trac will go back on after a certain amount of time, but ive never heard anything about when u press/hold it 🥴
Also i would say to compare it with another Supra without the damper issue...i wouldn’t be surprised if the suspension ecu speaks with abs or whatsoever
