hey guys i just got my mr today from dubai it took a while to get here and finally i just got....guys there seems to be a problem im getting worried now.....

ok so i put the car in d and its in normal mode when i start to tap the gas to accelerate gentelly it jerks for a sec then goes normal after the sst seems to be shifting fast and no slipping at all.....then once i put it in s sport and turn off the asc twice to fully tuen it off i push the brakes and i hit the gas it went up to 5k rpm then let off the brake then it over revved then it said trans over heating slow down :S bummer man.....i just drove it normally then while at a traffic light i was parked put it in N and it said gear box maintenance required ...then gave me the msg again over heating slow down and it won't move in d its like there is no gear selected.....i turned of the car and turned it back on then put it in d and drove back home.....guys please dont tell me i have to change the gearbox i just put all my money on the car and it has no warranty........

 

Hi,

I'm guessing your trying to launch? If so make sure you press on the breaks hard, if you are just holding the breaks so the car doesn't move then you will have a transmission warning.

Hope this helps,

Nichi

 

hey nichi i did press it hard i tried it a few times still isn't working .... even after a normal drive i parked at a traffic light it was on d and normal mode i put it in neutral and suddenly said trans service required then it said trans over heating slow down while it was parked.......

 

Steps for launch control.


NEVER EVER TRY THIS IN NORMAL OR SPORT MODE.

Step 1.put car in s-sport mode, this is once you set it to sport mode, hold it for a few seconds. It will indicate s-sport mode.
Step 2.Then hold the asc (stability control) for 3 seconds until you see a message AYC off.
Step 3.Then you hit the brake hard & hold it at the same time.
Step 4. Hold gas til it hits 5k, as soon as you get to 5k let off the brake.
Step 5. Enjoy your launch control.

You may want to add a additional oil cooler, as the overheat slowdown message will happen a lot when launching with normal temps
in high temp/humidity it will destroy your clutch packs from overheating.

You may want to change your trans fluid anyway.
Good chance it's burnt up if it wasn't changed.
The TC-sst is a very expensive, the 1st thing you should do is change that fluid.
No launching until then, unless you want to pay for a transmission.
It's 12k usd.,

 

I understand why you turn off the traction control, but don't understand why people insist on also turning off the single-wheel braking help for the AYC. Can someone walk me through this, please?

 

It's part of the launch sequence.
When you hold down the asc for 3 seconds it disables the ayc.
Apparently this so the ecu knows you want to launch.

 

It's the only reason to turn it off is a launch.
Unless your testing physics

 

Let's be clear about this. Holding the ASC button down for three seconds does not turn off the AYC; it turns off the single-wheel-braking aid for the AYC.

Whether it also sends some sort of message to the ECU allowing you to launch the car is another issue, but there's no way to turn off the AYC using only a button.

 

Lets all be very clear that you don't need to hold down the asc for three seconds, all you need to do is have it in s sport mode with traction control pressed off. That is it. It will work either way, personally, I just have it pressed off, not 3 seconds off

 

Both of these are correct!

AYC is Active Yaw Control. The vehicles has pitch sensors and a number of gyros that tell the car what direction the car is moving. If that is inconsistent with the steering wheel position sensor, the car will transfer power to certain wheels to correct.

Pushing and holding the ASC button for 3 seconds will turn of the Active Yaw Brake. The Active Yaw Brake is will apply brakes to certain wheels to cause the car to pivot off of that wheel, IN ADDITION to the AYC.

There is no need to turn this off to launch your car. Launching your car does require you to turn Active Stability Control off however. Active Stability Control is like AYC and AYB, but for straight lines. If you car starts to slip one direction or another as you are going in a straight line, the car will correct by applying brakes. THIS is the feature you want off, as it can hinder a launch!

Iowa, as to why people to off the Yaw Brake, some people have this attitude of "I'm a man, I drive my car with skills. I don't want the car to drive for me. It makes you a lazy driver." I disagree, I leave my yaw brake on even on the track. But w/e I guess I'm just a lazy.

 

I still appreciate that an EVO and most other sports cars allow you to fully disable anything that would be practical to disable in terms of stability/traction control. Even if you wouldnt have much of a reason to turn off the AYC brake. I think it's partly an advertising thing - car websites can list "fully defeatable" everything in the pros column of a review.

 

We don't seem to agree on all of this....

I don't think that the car has "gyros"; just a three-axis accelerometer.

And inconsistency between steering angle and (inferred) motion only triggers parts of the ASC (namely: the single-wheel braking); it doesn't do anything to the ACD or AYC that I know of, so I don't believe that any change in power distribution occurs.

To be precise, the wheel that gets the braking is the inside rear. No others are used for AYC help. Yes, others are used for ASC, but not yaw.

Not sure what AYB is, but you should probably be clearer about which aspects of the ASC are used when turning vs going in a straight line. What deals with straight-line stuff is Type-1 and Type-2 traction control, as in cutting the throttle and applying the brakes to the slipping wheel. The other aspects of the ASC are for when the car oversteers or understeers, which, by definition, is when you're turning. When the car detects under- or oversteer, brakes are applied to one particular wheel (e.g., the inside-front wheel to counter understeer). All of this ... the two levels of traction control and the fancier ASC stuff are all turned off with the tap of that button.

I believe that you're being too charitable and/or underestimating the negative effects of nonsense on the internet. I would guess that a majority of people who hold the button down for 3 seconds before launching are doing it because they've read that they have to. You actually don't have to even tap the button, although launching hard with traction control activating is rather self-defeating.

edit: I just figured out that AYB = the single wheel braking help for the AYC

 

Wow, I hate to disagree but c'mon.
You can't launch with traction control enabled.
The car cuts power if I hit the gas to quick & the slip light picture of the car with curved lines appear.
I'm sure the reason you hold the button for the 3 seconds is to let the ecu. & TCM know your launching.
Maybe you can launch without holding the asc to indicate
Ayc on, but I'm not wasting my clutch on a suggestion.
Unless someone can tell me they launched the sst without doing that,then ill agree.
Why make you slam the Brahe pedal vs just holding to the floor. Because again, that's the only way it works.
I've never had a problem, other than a overheat at the track.

 

OK, now that everyone is done discussing AYC AYB ACS ABC and XYZ functions, could those of you with all this practical knowledge help guide OP as to why he is getting a transmission overheat alarm just sitting at a light and shifting from D to N?

I am going to assume OP, that you were not doing anything like putting it into N and revving up to 5K and then trying to dump it into D to create your own homebrewed launch because you could not get the OEM launch control to work.

 

Sorry. We did kind of go off on a longer-than-usual digression, didn't we?

I don't know the SST that well, but my guess is that the OP's problem is that he's in Arabia. Given the location of the tranny cooler, sitting still means no air-flow, so he's just overheating the unit.
