Oh well - It was exciting hoping for a radical improvement - NOT!!
I had a chance to try the ESP Disable this morning. Yes you can smoke the tires - but NO-It does NOTHING for the Tq Man'gmnt of the shifting of the tranny. You get the same delay as always and the shifting is not any firmer! :eek:uch:

I guess it's time to consider the GSM upgrade for firm quick shifts!
Anyone else with the same results?? :grumpy: :grumpy:

Quicksilver, how did you disable the ESP?

Are you sure it isn't the "shift hesitation" issue and not just a delay? The shift delay is just a very subtle difference IMHO and won't be very noticeable short of getting the tires to chirp.

Have you had the TSB done yet?

I'm not sure the TSB did anything for me. It still seems to cutoff between 1st-2nd.

Dont you just push the button and it turns off?

*dead silence*


Hey.........You're right.......Why didn't I think of that?





:D




In all serious no, it doesn't turn it off fully. It still has some control over the vehicle.

oh. I dunno if you've seen the srt vs cobra vid. The first race, the srt-8 turns off the traction control and just smokes the tires. also the week before when he smoked a 350z he did like a 75 foot burnout. I would think that means its off. Just imagine the badass brake stands with it completly off :eek:

Nope, it's not, but keep in mind ESP does more than just traction control. There's yaw control sensors on each of the 4 corners for handling, ABS, Brake assist, and engine control torque management.

These systems do a lot more complex functions than just keeping the tires from frying.

AFAIK, it never was claimed to have any effect on the torque management, which is not part of the ESP system, to my knowledge. What this does is two things, again, AFAIK,

1. Stop the traction control software from applying one brake when it senses that wheel begin to spin faster than the other.

Dont confuse this with anti-lock, which senses incipient wheel(s) locking up, where the wheelspeed and road speed have varying values, as opposed to one wheel going faster than another like above.

2. Stop the stability controlsoftware. In a turn, if the yaw sensors and other sensors agree that some part of the car is travelling in a bad direction, the ESP can apply any one or more individual brake to "rotate the car" around that wheel to alter its angle through the turn.

So if you hammer the throttle in a turn, and break the back end loose, the car will sense that, and apply a specific brake to stop that from proceeding to the point that the car is out of control.

Spent all day TODAY at Sears Point (aka infineon) Raceway in Sonoma CA pushing my 2 week old 06 Black SRT-8 through 12 turns with about 17 other car enthusiasts.

ESP on, ESP off. All manual shifting, all Automatic.

I would love to say that esp off, manual was quickest.

Ummm. Damn semiconductors. Full Auto, ESP On = Sick

That 4180 lb rocket sled devoured most cars with ease.

Cars in Attendance (partial list) Porsche 2001 twin turbo, Supercharged Porsche convertble, 2005 Corvette (bone stock like new) Acura NSX (Race Set-up Carbon fiber...) Mustang GT Convertible (with Nitrous) Cooper Mini, BMW M3 (stock) and M5 (very not stock), FireHawk, Honda S2000, Mustang, Camaro... & My SRT-8.

With ESP, Shifting Manual (mostly 2nd to 3rd and back) and Automatic = Passed all but 2 of the above, some repeatedly. Out of respect for my fellow drivers, I won't say which 2. Hint: It wasn't the two most expensive.

Said one driver after a 25-30 minute session: "Did you lap me three times?"

My reply " No, only twice, I pulled into the pits once and passed you again."

"Oh" he said, then walked off.

Regarding the ESP. With the traction control, and the yaw control, and the abs... This car helped me get better lap times, and stay on the track, and not eat any tire barriers etc...

I was interested in totally disabling the ESP (#17 etc,,,)
Not anymore. My two ton fire breathing SRT-8 that devoured Sears Point with ease convinced me that 425hp, me and ESP is better than just 425hp and me.

The button lets me roast my tires at will. The rest of the time, gimme ESP.

Race School = $495
Fuel = $150
New L/F Tire = $275

The looks on Drivers faces when they saw a rearview mirror full of SRT-8, a black flash, then my dust =Priceless

Everyone Dies, Not Everyone Really Lives.

Gotta Go, the open road beckons...

The car mags used to test the "manual" shifting versus just leaving it in D back when it was a novel feature. Every time D was faster, and they eventually stopped comparing.

Now if we could only get the "Tranny" to shift @6200rpm into each gear everytime with no Tq Man'g'mnt - we would really have a "WINNER"

OH - Calling GSM-Any possibilities of this??

As much as I love shifting eevrything I own at redline, every DYNO sheet looks the same with max hp not at 6200.
And btw we DO Have a WINNER! Judging by the look on the Super Charged Porsche owners face, and every other driver sucked up and left behind by my BONE STOCK SRT-8.

Yes, but the HP at redline in one gear is virtually always higher than the HP available at the rpm immediately after the shift. Especially when you take the leverage of the gear ratios into effect.

What Dyno Sheets are you looking at?? - Everyone I've seen, the HP is still climbing @6200, however this is the redline for the car, hence it is time to shift to the next gear. I'm interested to know what Dyno slips you're seeing?

Every DYNO sheet I have seen on the forum regarding CAI, Catbacks, 3" Cats...
