hmmmm I can see the andymod in my 4 Runners future.....

and RickyCRX I know you are going to do this!!

Let us know how it turns out..
 
What part of "I don't need anybody saying, "But those systems are designed to protect you, blah, blah..."" did you not understand?? I don't need anybody attempting to preach to me about this. For DECADES there was no such thing as traction control. Your mom and dad and their mom and dad grew up their entire driving life without any sort of electronic 'crutches.' Why do we all of a sudden need them now?!?!?! Are you saying that you are much less coordinated and less fit to handle a vehicle than your ancestors??

Seriously. If I have managed to not roll over an S-10 Blazer in the last 14+ months and 18k miles, I think the 4Runner minus traction control only on SOME occasions will not be a problem for me to handle.

In case you haven't noticed, the Blazer is rated as one of THE highest rollover risk vehicles on the road and I haven't had even the slightest hint of it feeling like it wants to go over. As I said before, THE TIRES DON'T HAVE ENOUGH GRIP to flip a 4Runner without hitting an immovable object (like a curb, or going down an embankment, etc)!!

And reading up on that Andymod thing on yotatech, I have a feeling I may have to install a momentary switch next to my "TRAC OFF" button to break the connection of that one connector on the master cylinder... This should be fun. I'll have to do some testing to make sure it works on my own vehicle, though.

I'm with Thai on this one - however great a driver you might be there are always other drivers on the road who may not have such cat-like reflexes and experience. There are plenty of posts on this board from people who have had some pretty nasty experiences, many of them not their fault - turning off ATRAC and/or VSC reduces your chances of escaping such an incident unharmed.

Toyota designed the 4Runner as an integrated system - adjusting for the top heavy design by introducing systems like VSC and ATRAC to reduce the risk of a rollover in particular. Studies have now shown how big a contribution VSC makes to reducing rollover rates and we are all painfully aware of the high mortality rates in such accidents. For everybody else's sake if not your own, please don't turn these systems off - just accept that the s2000 is the car for fast cornering etc and enjoy the 4Runner for what it is.

Will do!!

This will take care of the ABS motor not cycling, but unlike previous Gen's of T4R, the 4th Gen is drive-by-wire. How are you going to get around the dethrottling?

Ricky,

I understand what you would like to do with the 4Runner. I too would love to have COMPLETE control, when I want to.

You made the statements above that I felt needed to be clarified. There is no way ANY person can do what the stability control can do (apply braking to one wheel). Also, if a SUV/Mini-Van type vehicle (vehicles with a high center of gravity) experience a rear blow-out and the vehicle gets sliding sidways, it can flip.

Personally, I think it would be unwise and/or dangerous to drive around with these systems shut-off. But, at the same time there are certain conditions where it would be desireable, like in deep snow or muddy conditions where sometimes you just need to be able to hold on and floor it to get through. But again, these are relatively low speed situations.
Just my .02.
 
Thanks for the concerns, but I'm only talking about wanting to turn this off for low-speed (<30mph) 'fun times' when I want to have it NOT cut throttle on me. I'm not talking about taking 35mph turns at 80mph and drifting the tail out around that type of a corner. I'm talking about taking a 90-degree turn onto a side street (that's two lanes wide with plenty of room for runoff) at 25mph and being able to nuke it without the rattlesnake of death. Guys, really... I'm not driving like a heathen here. You have to trust me on this one. PLEASE stop the preaching.

And you know what? I've been in many VERY low traction situations before where even with these 'protection' systems, the average driver would have still crashed. There are certain times when I don't give a cr@p what the car thinks needs to happen, I don't want ANY braking going on because I NEED 100% of my traction available for steering, NOT any of it divided up into braking (those who ride motorcycles will understand the concept of only 100% of traction being available and it can only be used for one of three things; acceleration, braking, or turning. It can be used for a combination of those three things, but when you use more of one, the other two must suffer.)

And regardless of whether or not I have a (unlikely) blowout on the highway, chances are my traction control will NOT be turned off at that point in time. Why would I even WANT to think about sliding the tail end out around a turn at 70+mph (the speeds I would be doing on the highway)?? It doesn't make sense.

Now, all of you that just want to preach, PLEASE... I'll ask one more time; TAKE IT ELSEWHERE. I just wanted technical discussion on how to disable all traction control/stability control/etc systems on a 4th gen 4Runner. I think the "Andymod" is the closest solution that anybody can come up with. I'll certainly be trying this out at some point in the near future.

My understanding is that if this sensor's connection is 'interrupted' going to the master cylinder, even momentarily, that it will trigger a 'fault' in the TRAC and stability control systems, thereby triggering them as 'inoperative' for the duration of that startup sequence. Once the ECU's go through their self-test on the next startup, they will see that there is no fault and will re-activate the traction control and stability control systems at that point in time.

So, it seems that IF you installed a momentary switch that would simply break the connection to that sensor even for a half second, it would trigger a fault and disable those systems for the duration of that drive, which would be perfect for the last half mile of my drive home each day.

Ricky,

You seem to have misunderstood my post, I was not preaching. You made statements that were not accurate, and I brought them to your attention. Nowhere in my post was I preaching, as a matter of fact, I stated, I also would love to have the option to disable these systems. I know it
 
Did you try the mod yet? TCS is way too sensitive. I can't turn onto the highway from a side street to merge with traffic without that damn thing going off.

I don't care what anyone says, TCS and the like were designed for the soccer moms that don't know how to control their steering, throttle, and braking. If you need those to drive your SUV your shouldn't be driving.

Lets us know how it goes.
 
Ricky,

I just wanted to let you know there are those of us out there that feel your pain. I completely understand where you're coming from and how annoying it must be to put up with the responses in this thread.

I've had 2 near brushes with disaster in my 4Runner simply from changing lanes in slippery winter conditions. In both incidents, the VSC cut my throttle and almost *caused* an accident. Personally, I think I'd be better off without this "safety" system.

The VSC stepped in and stopped your vehicle from spinning around. It SAVED you!

What part of "you bought the wrong damned SUV" do you not understand?

If you wanted to drive it like that you really should have considered a Cayene or something.

Man I hate it when people come to ask for advice on a forum like this and turn into a big smart ass.

If you're so smart why the hell can't you figure out how to:

a) Correctly identify the system that's giving you greif.
b) Disable the system
c) Sell your 4runner and buy a vehicle that meets your needs?



:bash:

I might believe that if I hadn't personally witnessed how VSC can be totally out to lunch and have no freaking clue what my car is doing. I can hang the ass end of my 4Runner 3 FEET out to the side before VSC wakes up and starts beeping at me. Then there was that time I got my left wheels into some slush that was slowly pulling me into to the median. Steering to the right had no effect. If VSC had applied a little braking to the right side wheels, that would have been very helpful. Instead, all I got was beeping. Thanks Toyota...

Thanks overdrive, for giving us the moron reply of the day. I don't recall Ricky asking for safety advise or soliciting opinions of the effectiveness of VSC. And yes, it makes total sense that Ricky should buy a different, much more expensive SUV simply because he'd like to disable a feature on the vehicle he has now. How much do you know about the integration of the various systems on the 4Runner?

The only time I've had the vehicle come around was from a dead stop and hitting the gas hard in the snow. The left wheel scenario should have triggered the traction control if the wheel lost traction. If the wheel didn't loose traction no system would have been triggered.

I think the system in the 4Runner would work much better if it had the Vehicle Dynamics Integrated Management (VIDM). This system integrates braking, steering, VSC, TRAC to help minimize loss of traction in a turn. It helps the driver maintain control under adverse conditions. It factors in speed, road conditions, steering inputs that can affect VDIM
 
RickyCRX I feel your pain as a fellow AXer (I got Miatas) it drives me mad my 2wd '06 runner has an overprotective nanny riding along in the dash. You would think they would give you the ability to shut it down.

Have you had it do the rollback routine where it sounds like it has a electronic seizure id it rolls back on an incline while in drive.

I'm sure Toyota installed this electronic crap to keep your average soccer mom, and no driving on the phone business clown safe, but some of us do actually "drive" our cars!
