TOYOTA / BMW, FIX THIS!!! TC/ESC Issues on MK5 Supra. 

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.

BTW, shout out to the editor for the warning light coming up every ***** word 😂😂😂

Car: "Tyre pressure low. Stop carefully" Misha: "You have no power here!" Car: *engaging ESC*

I guess that's Karma for making fun of George in yesterday's video (the lap before).

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! 🤜🤛

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.

As long as this tire pressure warning is active it will continue to happen, the car "thinks" it has low tire pressure.

Customer - "TC OFF" Toyota - "It's just a prank, Bro." 😅

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 +

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.

You are very brave to drive this that quick knowing this 😂 great video Misha.

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.

well done, amazing lines you have while racing man. And good info on the supra

Misha finds out the colour of adrenaline is brown 🤣

This camera display setup is awesome! Yay! 💚 Also, ‘aahhh!! , that was the prime f’ing example!!’ 🤣💚

I learn a lot on this videos! Exellence driving!

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.

You should talk to Jackie Ding he had the same issue on his time attack supra. Pretty sure he got it figured out.

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

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.

The "NOPE" at 4:17! Hilarious :D

Good to see someone actually reporting issues on the supra, everyone in the US is raving about the a90 supra and its awesomeness...

Here before BMW Supra comments and George and Tristan) god I like that:. Thanks Tristan!

Lol thats exactly what I noticed when coaching in a Supra and I didn't know what to think of it back then

his face while going out of the Karussell represents the whole video

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!

Same here in the 2021. I had to do an alignment to correct the passenger rear wheel (LHD). It was toe out.

Commented on George’s video also - it’s the ride height sensor/adaptive suspension.

Maybe it's because of the tyre pressure warning? Edit: maybe that's the reason it keeps popping the tc on again

Je rijdt echt ziek goed man.

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.

Can you reprogram the ECU to remove/permanently disable traction control?

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 definedcoding to code GTS into your sports+ mode. It’ll get more slip angle without intervention (traction light)

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 🤷‍♂️

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 is because of tyre pressure warning. I had the same with my M135i

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.

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.

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.

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’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.

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 press LIKE not because you nearly crashed Misha but because I like the time and effort putting into making this video!

PHD racing Supra also had the same issues with tc randomly turning on

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?

Could you not get someone to re program the ecu or some computer module?

4:40 "Tire pressure low. Stop carefully." Misha, who went past Antoniusbuche going 208 km/h: *_N O_*

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.

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.

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.

1:15 was when the VSC turn back on, for no reason. 4:17 too, just moment after you turn it off.

I have a similar issue in my FN2 type r, even spirited Street driving, if I'm turning over a crest it shits itself if the rear slips AT ALL, then it grabs a brake and tries to put me in a bush the opposite side

In most bmws there is a way to store/set current pressures in the iDrive, I wonder if it is possible to do the same in the Supra. Unless it’s a system fault or the sensors are malfunctioning.

Good that you are an experienced driver. Sad traction control a problem. You deserve , car not so much.

nice viedeo Super !

Get OBD plug with adaptation capability and change ESC settings from there. Works on VAG/AUDI, BMW has its own versions.

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.

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!

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

Only due to tire inflation warning. I had similar issue on Dijon’s track but after inflate a bit thé car was clean.

Does the "pedal dance" work on the Yaris ? That is essentially "dyno mode" and will fully disable vsc tcs.

Misha, is this a problem with both 20 and the new 21 model? Do you know if a base spec 3.0 has exactly the same issues?

I had the same problem, and was scary

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!)

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?

Ryan Tureck got some sort of the same problem trying to drift the mk5. There was something going on with the tc.

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.

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

I wonder if the traction control is automatically turning on because of the TPMS?

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

Good video

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

There are many dangerous things in driving fast but nothing like unexpected and out of driver's control things

My supra doesnt show this behavior, if I remember it correctly. But I will test it tomorrow.

I felt this one. Thats some final destination shit, that is.

does the z4 have the same issues or are they just inherent in the supra and other performance toyotas

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.

i wonder if it’s like a moder bmw. if you press the esc turns off traction control but leaves on stability management. press and hold and everything will turn off.

Wondering if can tune the TC out of it and map the car before track day.

When the car decides you are crashing into a wall

Wait, you cant keep holding for longer and it turns off all the way? Like on e9x?

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.

Its weird that the traction control is shown in 3 different places on the dash

Same issue in "normal" modes outside of sport mode?

Does the new Z4 have the same suspension issues similar to the Supra? Also, that Clio was fast.

Is the TC not turning back on because it detects an issue with tires? As in, the tire pressure is, logically, low and so the car’s safety bs keeps activating TC?

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

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.

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?

Does the supra have a 'pedal dance' mode like the GT86 and Yaris do that properly turns everything off?

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

Was TC/ESC fully off? Ik BMW makes you hold the button for a few seconds to fully disable it.

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. 😂😎😅🤣

Even if your tire pressure is low or not set to factory you should still be able to disable it.

Dose switching vsc off turn esp+tc or esp only？

does pulling the fuse work?

some silky driving that lad.
