06 Magnum SRT8 ESP launching

[MagnumSRT8]

Been to the track with my car quite a bit and launching seems so inconsistant. Ive always disabled esp by holding it till its off, but every so often when i try to do a burnout i can feel esp kicking in even though its off. I know its not 100% disabled but just seems to change so much. I tried running with dyno mode on once but i just ended up spinning one tire till second gear. With the 93cai tune in a srt8 are the esp modes changed at all? would i be better off just hitting esp once instead of holding it?

I'm not sure you need to hit the button at all. You definitely don't need to press and hold. Here's how the button works stock.

Press and release:
Straight line traction control is disabled. What this means is that you can spin the rear tires and there is no intervention
Lateral/cornering pitch and yaw traction controlled is relaxed. The threshold of intervention is lowered and the intervention is less aggressive.
ABS is on

Press and hold:
Straight line traction control is disabled.
Lateral/cornering pitch and yaw traction control is disabled.
ABS is on

Predator dyno mode is all the above and I believe ABS is off.

Without pressing any buttons, simply installing a Predator tune will reduce traction control. The tune reduces torque management. Traction control shares one or more of the same tables with torque management. reduce torque management and you reduce traction control. Now, with a tune, if you spin your tires enough to engage traction control, I think your time for that run is toast anyway.

Thanks, ill give it a shot just leaving it on, havent tried that yet. How do you like your tune from RDP? I was thinking of getting an email tune, not sure if ill really get much faster than what i have already though.

Use the key trick to put the car into "Performance Mode". While running at 15mph or above, put the tranny in Neutral, and turn the key to the "Start" position and hold. You'll get the BONG sound and the "Mr Squiggly", ESP and BAS lights will come on. Traction control is now completely off, ESP is off, Brake Assist is off. According to some thing also increases throttle response, but I haven't seen any proof. With my old 300 SRT8 though I did frequently see .2-.3 quicker 0-60s.

I like it a lot! I got it a year ago? I think it was a little better than a canned tune performancewise at the time. Probably not any more. My car is basically stock (see sig). What I wanted was a conservative tune that was tweaked exactly like I wanted. Especially the torque management.

Steve (dynoSteve) will spend all the time you want on the phone to explain everything and find out exactly what it is you're looking for and your expectations (he's been living in Ohio for a year now but you still might need your Star Trek universal translator. Or you could watch Crocodile Dundee a couple of times to warm up ).

You send him your Original Backup. he will send you a tune and you'll send logs back to him, he'll tweak it from the logs and/or from what you want to see more or less of. Repeat as many times as it takes to make you happy. I don't think anything has changed since a year ago.

Tried that key trick , never worked on my car.

Quick, you ever run it at the track? I have about the same mods as you, except i welded in zoomers mufflers and took out the resonators in the stock cat back. and i have a air hammer instead of the afe. I managed to run a 12.72@110mph last year with my setup.

Holy crap! That's a great time! I only went once last year and failed to break into the 12's. 13.2 and couldn't get a 60' under 2.0. mainly tires, heat and a bit of a head wind (and I sucked at the tree). Going again on the 6th. I'm pretty optimistic with the Nitto NT05s. I haven't been able to break them loose yet launching on the street and it's improved my 0 - 60mph by a couple of tenths.

Did my best with the stock Goodyear eagle F1 tires, 1.96 60' time.

Being a newbie here I hope I am not treading on toes. I have just come back from a deserted road where I have been doing launches up to 100k's /hour (60MPH)
If I leave the management in stock trim (ESP set) I got a best of 5.1 seconds, if I did the quick push of the ESP button I got a 5.45 seconds, & if I held the ESP button for 6+seconds I got a 5.78 seconds. I guess I will be leaving the esp on.
I have just ordered my predator from Dyno Steve should be here next week then I can have a bit of fun.
I used to go to Steve when he was in Australia, best tuner I know ANYWHERE.

I put in a 91CAI tune on an 06 300C. My first two runs I did not touch the esp button and ran a 14.4 ET. My third run I pushed the ESP and turned it off. I ran a really bad 1/4 mile ET 17.76. I burned rubber half way down the track. I know the tune turns the esp half off. I did not think pushing the esp button would have any effect. Boy was I wrong. I got DSP to modify my 91CAI tune to leave the ESP and traction control fully on. I have not run at the track again so I dont know if it will help with my launch. I have been haveing trouble with traction on my launch. I know when I went to the SRT event they told us to leave the traction control on. We had faster ETs with it on but that was with street tires. I dont know if slicks would be differant

[Quick]

They tell you to leave esp on at the TE so you don't lose it and crash. Anybody with a driver's license can go to the TE and drive. I had to wait on the fist lap following some lady through the cork screw at Laguna Seca at......... 10 MPH!

IF you get wheel spin the traction control will first apply selective braking to the wheels and if that doesn't work it will cut power. It also reduces torque management when it's off. I believe it's the last part that will gain you time/power even when don't spin the wheels. The solution for spinning the wheels off the line is practice. Practice your launches. Practice rolling into the pedal instead of just slapping it to the floor. A Hemi31 (Erik) was able to consistently do 1.8 60' times in his 06 magnum on the stock RSA's (the F1's are better for traction off the line).

[MagnumSRT8]

When my esp kicks in it seems to cut power right away so i dont see how anyone could run faster times with it on. I just got some Vredestein 275/40/20's so im gonna see how well those do at the track. 1.8 60' times on rsa's is insane, i'd be happy pulling 1.9's hit the 1.9's a few times 1.96 i think was my best on the f1's. The last few times at the track i had some really crappy hankook tires on the back with a 420 tread wear rating, and i still managed to pull a 2.00 60' time on those so im expecting a major improvement with the new tires.

[Quick]

The Vredesteins are pretty slick if it's cold. If it's above 60 or so they should be an improvement or at least equal to the F1's. The Vreds are very good on a road course. For your next set of street tires get the Nitto NT05's. Currently, for a street tire for your car, they can't be beat at both the strip or the course.
