Traction Control Questions

[nwsewell]

Let me preface by saying: on wet roads, gravel, sand or any similar condition, i have no issues breaking the rear tires free with traction control off, and it does not give me any hassle.

But I recently tried doing a burnout and a couple donuts on dry concrete to check those off of my bucket list since I've never actually done either before, and my truck was NOT having it.

'19 Classic. 5.7. 8,000 miles. Vararam. Pedal Commander set on Sport. 2wd. 3.21s. LSD.

I turned traction control off, held the brakes, and eased onto the skinny pedal. The back tires were trying to break free, but it sounded like they were skipping or hopping; and the traction control light in the cluster started flashing at me.

Dissatisfied with how that worked out, i tried whipping a couple donuts, and had a similar outcome. Turned off traction control, cut the wheel to the side, mashed the gas. Tires were chirping/hopping, traction control light started flashing again. The rear end did slip out a little bit, but not how I was expecting after seeing many others do it.

After two dissatisfying attempts, i called it quits and drove on.

Any idea why my truck might be behaving this way, or what i might be doing wrong?

I forgot to mention, the next time i started the truck, a message popped up in the cluster for about half a second before going away that said "service electronic braking system"
Only saw the message once, extremely briefly, and have not seen it since. No lights or anything of the sort on the dash

This is normal. When you hit the button it only shuts it off like 60%. Stability control will prevent you from doing donuts and burnouts. Even when ur hard on the petal off an intersection abs will kick in and limit you, some vehicles even retard spark timing so the engine doesn't make power and brake wheels loose. Only way around it is a tuner or pull ur abs fuse when you want to play. Goda love how they neuter the trucks these days. In 4x4 if you hold the squiggly button while in neutral it will shut the Traction control completely off until you hit 40mph.

The only way to fully eliminate this is with a tune. ESP is very intrusive on these trucks and having driven mine in the rain with ESP and torque management disabled I can see why FCA handles it the way that they do. For some of us it is fun, for others it would end in a wreck.

Thank you for the reassurance. I was very scared that I did something to **** up my trucks electronics.
Looks like I'll have to confine myself to playing in the rain until I feel comfortable tuning the truck (which won't happen until after I upgrade tires, swaybar, suspension, and probably driveshaft)

Like Brandon said, pulling the F26 fuse will disable the ESC & TCS.
Or
To turn it off and on, on the fly in any mode, 2wd, 4wd auto, 4wd or 4wd low:

Wire in a 30amp fuse from F26 socket to a 30amp NC (normally closed) relay.
Wire in a dash on/off switch to control the relay. Or, I used a remote-controlled wireless switch
to control the relay and linked it to a HomeLink (garage door) button. This saves the trouble
of pulling wires into the cab and installing a switch.

If you feel any wheel hop at at all during full acceleration from a stand still you need to get a set of Core4x4 Lower control arms. They will stop any wheel hop you have and will help plant the rear end of the truck------period!

Thank you for the recommendation! I was definitely planning on getting the hellwig, but was unsure if those control arms would have any benefit for my 2wd truck.
I also want to upgrade the shocks and springs to something a little stiffer, but keep the factory ride height.

Just pull the fuse as stated above; but it will also disable ABS. Not safe for daily driving but works if you want to have some fun once in a while.

Doesn't tazer delete the TCS when you hold the button longer??

ESC is the problem. If you keep the truck pretty straight with the traction control off you can manage a pretty decent burnout..........but if the rear starts to step out in the SLIGHTEST bit, the electronic nannies reign in the fun.

Traction control does exactly that, limits wheel spin.

ESC tries to keep the rear end from passing the front (and cannot be fully disable unless you pull the fuse, hit 4low, or tune it out)

The issue I'm having is that the wheels don't want to really burnout with traction control off. It sounds like theyre starting to spin and stopping super fast repeatedly, as if ABS is engaging, and the traction light starts flashing at me.
On wet or loose road conditions, they spin properly with ease, both with just the skinny pedal, and with power braking.
My truck is only 2wd, if that makes any difference

Gotcha. If the light is flashing at you then it’s “working” per say as it will flash when it’s “on” trying to do it’s thing.

As stated before, you can disable traction control but not quite 100% and your ESC might be attempting to through it’s $0.02 in on the situation. Also, if you are starting get wheel hop it might try to intervene since that action is actually pretty violent for the driveline............of course if the dagum tires would just burn into a beautiful haze you wouldn’t get the hop in the first place!

Shouldn’t be this hard for us to go Bo Duke style!


EDIT: FWIW, I had my tuner dial both back and I can clean ditches at will

Im very much looking forward to tuning my truck [emoji23]

Just to check from an earlier post, is it possible to make the traction control button completely shut off TC and ESC? If so I'm emailing Jay Greene!

 

[John Jensen]

Yes,

The answer is yes. Att is my PDF file describing same. Also, the SFT ECM tune includes, at no extra charge, the ability to turn off traction control. Att is my PDF file of instructions.

Hmm I guess it’s my 3.92s with anti spin. i have a 18 hemi sport night 2wd and with tc on it spins pretty good but with it off I can smoke my tires with no brake just punch it also this is with factory 20s.

John,

Thank you so much! This is really an extraordinary contribution, I truly appreciate it!

Is there any chance you could post an image of your modified setup? I'm definitely interested in replicating that in my truck.
