Acceleration grip for autocross

[Dusterbd13]

At the grm challenge this past weekend, traction and such were an issue. This is primarily an autocross car, so keep in mind the ecs button is now always getting the long hold.
Currently shod in kumho v730s

I have an off the shelf cobb accessport. I noticed it has traction control settings to add its own. I also noticed it only has stage 1 and two tunes available in it for some reason (wheres the stage 3??).

Ultimately i KNOW an actual limited slip is the correct answer, but those are $800 plus install from whoosh. As the challenge is a budget limited event, and i hope to return and finish higher than 10th overall, i want to explore other options.

What does the cobb traction control do? How well does it work? Is there a cheaper than 800 option that works better?
Wheres my stage 3 tune for when i CAN lay down power?

The Cobb TC just retards timing instead of also reducing boost and throttle. So it’s a much more limited intervention, and you can still definitely spin the tires - it just gives you a little more wiggle room on your fine throttle control. The effect is barely noticable but it does help slightly to avoid breaking traction, but more importantly it makes it easier to regain it without totally lifting on the throttle, since it’s keyed off “slip” and wheelspin. The baseline where it kicks in is actually somewhat high (supposedly 20% slip vs the stock TC activating at 8%) where slip is wheel speed difference F/R

Most AP tunes can be set to give it to you at a chosen setting by default - even at its most aggressive setting, it’s very subtle unless you’re really paying attention.

In second gear from a dig I can sometimes break it loose by stabbing the pedal to the floor but third gear in a straight line is pretty solid even with a ham-fisted throttle on a stage 2 tune.

On the track, even third gear coming out of a low speed corner, I can still break the inside front tire loose and traction management is still tricky. It’s enough that I never really get wheel spin coming out of hard 4th gear sweepers on 200TW tires.

Will the AP allow you to install ONLY their traction control, without also fully installing one of their numbered 'stage', canned tunes?

In what sense? It needs to be loaded as part of a AP tune because it’s in Cobb’s base software for the ECU that all other “tunes” are based on, (so not the stock tune), but it’s available for all the aftermarket tuners that use Cobb’s Accesstuner to enable. Unfortunately with the “canned” Cobb tunes it’s there but defaults to Off and you have to manually enable it every time you start the car.

But Dizzy, Stratified, Tune+ etc (anyone who uses AP tunes) can give you a tune with it enabled by default at your setting of choice.

Note that with it enabled it replaces both Sport mode and ESC off modes with Cobb TC mode, but in both modes, ESC is completely disabled beyond just the timing retard only based TC

Want to make sure I'm understanding this part correctly. The Cobb traction control will work regardless of mode the rest of the car is put in. However all the other nannies will still be active unless turned off via the switch or disconnecting an ABS sensor. Correct?

Yes, I was asking if it can be installed on a fully factory stock tune, as I am becoming increasingly paranoid of even the 'safest' canned tunes (or even custom tunes) out there as far as our little powerplant's longevity is concerned.
I figured it could not be, but wanted to ask anyway.

If I am reading the above correctly, if a tune with Cobb's TC is installed, one does NOT have to physically hit and hold the ESC button on the console in order to disable those nannies (at least as much as is done by holding that button on a full factory tune) every time the car is started, correct?

Maybe I will call Monster Tuned and ask what their options for TC are currently, since their Adapt-X Tune seems to be the absolute 'safest' tune available out there currently.

You still have to turn ESC to either “Sport” or “ESC-Off” mode. “Normal” mode still keeps factory traction control nannies on like usual

@M-Sport fan I’d not be that worried about a Stage 1 flash tune on longevity as long as you keep up with your maintainance and get gas from a reputable top tier station that has plenty of turnover and is less likely to slip you some low octane. The ECU still has plenty of flexibility and knock detection to handle things like bad fuel, even on an aftermarket tune. It’s basically the old school equivalent of “turning the boost up a bit”, but more sophisticated and safer.
