Traction Control memory module installed
 

I hate the fact that when you shut off the traction control your settings are forgotten every time you turn off the car. I purchased a module from KP Technologies that remembers your traction control settings and resets them every time the car is started. If you have it off it will be off the next car start and if it's on it will stay on. The install was very easy, Maybe took 25 minutes and I now have my TCS off every time I start the car. This does not do the pedal dance so there will be some TCS function still in place.

To put it in you pop off the shifter surround by pulling up on the inside of the boot. Now you can unclip the TCS harness from the button cluster. I was able to reach my hand into the center console and unhook the cigarette lighter connector- These are used for power and ground. I then used vampire clips to connect the yellow of the KP unit to the white from the cigarette lighter and the black to black. The Orange(all though it looked red to me) wire from the unit goes to the green on the TCS harness. Here I had to use a very small uninsulated butt splice and then heat shrunk over it. The green wire is very small. Velcro(not provided with module) was then used secure the unit in the center console.

After the install you start the car hold down the TCS button to have the module learn the setting you want and your done.

The unit is KP Technologies Flexible Memory Module #FM20 and is available here for $50-

Hmmmmmm this may be worth getting.

Could save me from my having to perform my startup ritual every time I get in the car (except in inclement weather) :)

Would people want something that does the pedal dance for them?

You know it's free to pull the abs fuse aye?

But that's dangerous. The aids hold the car together and not running them means the car may explode.

Really Captain? I've installed these in a few cars and with out a doubt there's always that guy(you) that says it's so hard to push a button blah blah. Nobody cares how motivated you are to push a button. Most are not. Didn't your mom ever tell you if you don't have anything nice to say then shut up.

Or you could just hold down a button for a few seconds... like was mentioned.

Those are safety measures and are there for good reasons.

Did you really just say most people are too lazy to press a button and then chime in with: if you don't have anything nice to say then shut up.
:slap:

If you don't like the mod good for you. There are lots of things people do to their cars that anyone of us could have a problem with. If you don't like it keep it to yourself.

Tahdizzle- It's there to keep toyota out of lawsuits and inexperienced drivers out of the woods. Remember Porsche was sued and lost for not having TCS on the GT. I'm older, angry(obviously) and been driving RWD cars for a long time. I have yet to put one in the woods or even off track. For me it's causing more problems then it's solving. The TCS to me is way too sensitive. A lot of time taking off from a stop while turning it will cut power with just a small amount of wheel slip. My first gut reaction is something has gone wrong with the car, motor died etc. Not exactly what I want to be worried about while pulling out from a dead stop onto a 70mph road(It's a very dumb texas thing having open access high speed roads). Also when the rear does start to step out you react and correct. Problem is the you are correcting for a problem the TCS has all ready solved and can end up unsettling the car even more.

If you feel more comfortable with it on then more power to you. I don't really care. Every one has their likes and dislikes and to each their own.

Where in Austin are you finding dead-stop turns onto 70 MPH roads?? I want to legally do that.

Out east on 71. I work right off 71 and everyday I have to turn west on it to go back into town.

It's not Scion it's our gov that mandates all things must default to full safety on, the nanny state is here to help you . Lawyers make up the nanny state's food supply you know.

No my mom taught me "if you don't have anything nice to say, don't say anything at all". Because telling someone to shut up wouldn't be nice to say to a person at all. Now would it? 😎

It's a good idea. Can't tell you how many times I wished I didn't have to press the buttons every time

No offense intended to anyone in here, but why does everyone feel like they need to turn TC and VSC off for daily driving?

You can turn very quick laps with both fully on, there's simply no need to have them disabled on the street.

If you find the VSC intervening a lot on the track, you're probably over driving the car unless you're a very competent driver needing a bit more rotation than the VSC is happy with.

No one "needs" the TC and VSC off all the time.

Lots of people want it off though (myself included).

Its annoying that its on all the time by default and I have to turn it off. I'd rather manually turn it on when I feel I need it.

And I completely agree with OP on turning from a dead stop into hard acceleration. Its jarring and annoying to have the damn TC kick in and kill power.
This happens more often than it should because the damn hard @ss rubber these stock tires have. The tires slip at the slightest hint of acceleration on most of the blacktop roads around here.

Because #racecar and #tokyodrift.

Nah honestly I agree with you. Normal daily driving, I don't bother to turn them off. This past Friday, I turned vsc off while running the tail of dragon, simply because each hairpin was causing tc, granted it's understandable. 90* turns at 40mph I would expect it to correct.

If you are on public streets/highways/freeways and you get the VSC in sport mode to slap you on the wrist... You are not driving safely.

There are a bunch of people who will chime in "I've been driving for XX Years, and have experience doing XXXX.."

No one is as good as they think they are, and thats not the point at all. On public roads, you have to worry about the other idiots too.

This dude (i assume) is kinda giving a
review, and linking a product. Not debating when where to use the system.
Use it or don't.
When you want, where you want.
Live a lil.
Ease up.

This isn't directed at you, just general commentary...

I still stand by my original point, if it's correcting you like that then you're over driving the car. If there is enough grip to take that corner at 40mph and you're giving it smooth and correct inputs then it wouldn't be intervening.

You should be able to drive the track (or road) in the current conditions without relying on VSC to correct you before ever considering turning it fully off. If VSC steps in before you have taken any corrective measures you don't have the skills to save it without the nannies.

All that said, driving with VSC in sport mode on the street is still very safe, it doesn't give you much room to screw up before it brings you back to a more stable place.

I was at an HDPE over the weekend, and my instructor has a BRZ. We spent some time probing just how much the VSC will let you get away with, and the only time it stepped in was either when doing bad things (erratic inputs, etc) or when trail braking too much to get more rotation. Chances are that if you're working on perfecting trail braking harder, your skills are already very good though.

Some people seem to think that disabling VSC gives the car higher cornering limits, which it doesn't. VSC doesn't limit grip in any way, it just regulates slip angle.

I hope it's not towards me, because I said I agree with you lol. Under normal conditions you shouldn't have to turn it off(is it technically turning on it? Maybe that's where some confusion comes in. I consider when I push the button it turns it off).

I only gave the example at the dragon because it's not a very forgiving road, and on stock tires you could tell they were wanting to spin in the constant hair pins at ~40-50mph. With all nannies on, I could literally feel less power throttling out of the turns, with vsc off car felt normal. Was I driving faster than I "should", that's a definite yes. But, it's part of "conquering the dragon".

That sounds more like TC than VSC. You'll know VSC because it will add brake to one (or more) corner to stop a slide. VSC sport mode does give a bit more lenience in wheelspin before TC kicks in too.

For reference, I consider VSC on to be how the car starts up normally, VSC sport if you press the sport button, and off is holding the TC button for a few seconds until TC and VSC are off.

If you're getting wheelspin mid corner, you're probably on the gas either too soon, or too hard before unwinding the steering angle. It can be fun, but it's slower than waiting for grip.

I disagree with these comments. You should check out the video of the guy who went off track when the nannies freaked out over curbing.

Also, I track in diagnostic mode and frequently explore the car's limits. Even in sport, the nannies kick in anywhere from parking lots to roundabouts during daily driving. They can really make the car unstable when they intervene when you are expecting a certain amount of rotation, even when driving smoothly.

If you are on track using the nannies, then you aren't learning the nuances of your car yet, and if they aren't kicking in, then you aren't pushing your car, which is fine, not everyone wants to beat on their car or has the skill to push it yet.

They aren't there to save you on the track, they're there for stupid people who do overdrive their car or don't possess the skill to save the car during emergency situations.

Now, I typically leave them on for dd but can see the value of this product, if it did the pedal dance.

Just ordered thx

Re-read what you quoted... I'll stand by what I said originally.

Until you have the skills to be driving without VSC kicking in, you shouldn't be disabling it. I'm not talking about people with lots of track experience pushing for more rotation, etc. I'm talking about beginners that lack the experience to properly correct without VSC saving them.

On one corner bump of my daily commute, VSC almost always squeezes the left rear brake, which upsets the car more than the bump does, even in sport mode. It's not a perfect system. Still, I usually leave it on.

Do USDM cars get different TC/VSC programming than the rest of the world? In the dry I can make the OE Michelins spin loudly and the TC won't do a damn thing about it. On mountain roads I drive with VSC Sport mode, and if I run over a pool of water I MUST correct it myself because VSC won't prevent me from going into a wall.

It has been said before: "IF you drive this car on the street in such a way that the nannies are 'interfering with your driving style' then you drive like an asshat".

To my knowledge, nobody has fully or at least publicly explored the VSC/VDC/ABS hardware and software.

@wparsons This is the kind of intervention I am talking about. I cut down your quote on purpose because I agreed with the rest. For such a low powered car, the system is highly intrusive. When you let the car correct your mistakes, you aren't learning. Sometimes those corrections can even be dangerous.

VSC isn't for high powered cars... TC is (to control wheelspin), VSC keeps a car from spinning out. You can spin a car with way less HP by lifting off the throttle at the wrong time.

My whole point is that if you don't have the skills to correct it yet, you shouldn't be disabling the system on a track. You should be learning basic car control on a skidpad or autox where it's more controlled and speeds are lower.

That I totally agree with. I think we're saying the same thing from different perspectives.
