Impreza WRX STi STI + Traction Control = Slow?

My 2012 STI seemed like it had the acceleration of my 2002 WRX until I turned off the traction control.

I may do dyno runs with the traction control on and off to see the real difference. It felt like a good 40 hp change.

I find it hard to believe that this is how the traction control is supposed to work, particularly in a straight line on dry pavement. It was like severe boost lag, and then the boost never really comes on.

Now the startup sequence is: Engine On, Sport Sharp, Traction Control Off...

it should only work when it senses a lose of traction. I know i have a wrx and it is a diff drive train but it will bog with traction control on when i lose traction on a launch. I just launched it a min ago on my street and i spun the back tires for a split second before it cut some of the power.

You probably forgot to change it out of Intelligent mode . Either that or your butt dyno needs calibrating...

Is there a way to always have traction control off or do we need to press the button every time we start the car?

My traction control only interferes if I shift into second super fast and aggressively at WOT. It kicks on for a second and spoils all the fun.

This sluggishness wasn't related to launching or shifting gears. Just merging onto the highway in third gear felt like no boost from 3000 rpm to 6000. Lugging 5th gear was actually quicker. I think it's sensing wheel slip and electronically cutting boost/timing/throttle/whatever. The question is whether this is a bug or a feature...

If nobody else is seeing this, which I wanted to determine by the General post, then it is a bug in my car in particular.

That sounds more like a crappy stock tune.

Yes, there is a device that costs about $100 (its been awhile since I posted the link and looked at it) but it will save your setting so everytime you start the car it will be the way you set it. It controls your TC, SI, and dccd modes.

http://settingsaver.com/

Looks like they are out of stock though

I turn my TC off pretty much everytime I get into the car (red not green) but never felt a difference in power unless I was loosing traction. This doesnt sound like a TC problem.

i havn't seen tractical control interefere with my cars acceleration..... and I have stage 2 protune where it might actually cause it to fire off if I launch it hard.

I think its voodoo.

I think i've only seen it go off a couple of times and at the time I was driving on gravel.

Traction control absolutely sucks going up steep hills in the snow (many in my area). Had TC on my '09 WRX and would usually turn it off, but a couple times I forgot and it would kick in and totally bog down the car. Completely ruins the "fun factor" and actually inhibits the ability to make it up hills.

Anything like this for the wrx? I'm getting a 2013 in April and would like to not have to turn tc off everytime I get in the car, not that it's a big deal or anything.

as mentioned, when i'd shift into second quickly...and sometimes third...it would come on and it was like hitting a wall. i quickly realized that pressing the button was imperative.

when i get in the car now i turn it off so the indicator is green, after turning to sport sharp and clicking one click down on the diff switch, to "-".

the car feels perfect that way.

and though it wasn't asked, add a cobb OTS stage 1 tune and it feels like a completely different car

i thought about the setting saver device but realized it's too easy to just click or press all three things once each time i get in the car vs. buying that thing and hooking it up.

Yeah I'll just have to get into the habit of doing it, only takes a few extra seconds. Thanks tho.

What is the difference between green and red mode?

Just press it once to make it go Green, that should be all you need to do. There are three selectable modes. Normal mode fully engages Vehicle Dynamics Control, Traction Control and ABS. Traction mode (Green Light) raises the threshold for intervention by the Vehicle Dynamics Control and traction control systems, thereby allowing you to maximize the torque delivered to the wheels. Off mode (Yellow Light) is for complete deactivation of Vehicle Dynamics Control.
