    Haha, I never broke traction on the 1-2 shift until I got a tune and was doing 1/4 miles on my "test track". First time it happened it was the strangest feeling... Made the 1-2 shift and then it just sort of felt like the rear suspension had gone soft and it was sort of wandering or floating ever so slightly. Engine rpms seemed in line with everything so it just didn't register what was going on right away. I just figured "it feels like something's wrong with the rear suspension but it's not too bad so I'll just stay in it anyway". lol It was loose for the better part of 1/2 a second or more and it hooked up so gradually you couldn't feel any bump or grab or anything. It was about the second time that happened before it struck me what was going on.

    Well... yes. I got a Predator about 2 years ago? and some time after that a RDP email tune from Steve. The test track is a sooooper secret measured 1/4 mile. Staging area disguised to look like a pull off just past the on-ramp from the pit area and an exit ramp to turn around 3/4 mile from the start. 7' drop from start to finish. 259' above sea level. :grin:

    Ahh... I see. Sorry, I took you for the um, resident know-it-all who didn't actually um, do stuff. I am corrected. I just wish I had my own super secret test track.

    Hmm, secret eh? Lets see your in San Jose Ca... Highway 9 is out of the question since theres not a 3/4 mile stretch of road thats straight, don't know of any exits on 880 or 101 that are only 3/4 mile apart. Could be HWY 1 since its close to 259" above sea level but thats a little ways from San Jose. I'll have to ponder it a while.

    Track's usually only open after midnight on weekdays... Good thing no one asked because I never did come up with a good answer for why I was on the side of the highway with a push broom...

    I´m not going to argue about HOW it works, but for the everyday runabout and (god forgive) lending it to someone like my mother, its a great thing!
    But if you´re serious about your driving and in a hurry to get somwhere and the road is twisty, you might consider turning it off.
    Here is my personal experience wiht ESP, about 300.000 miles in Mercs with the current system:

    * The system does not permit any fun ie no slides and no wheelspin
    * The system concentrates on slowing down if activated, aposed to for example Volvos systems that aim to help the driver steer where he/she wants to
    * The car gets very unpredictable (to me) in the "semi mode", you can push the car into a slide, but you can´t control how much wheelspin as the system only allowes so much, and if the car thinks things are out of hands, fast steering movements, throttle lift-off etc, the system steps in and ruins either your fun, or your progress...
    Mind you, if my mother got it sideways, I´d be happy if the system steps in, not that she´d ever get to borrow the car, let alone turn the ESP off.

    If you go to a circuit and leave the ESP on and pushing the car, your brakes will fry, as it uses the brakes almost the whole lap and that´s how you hear of Porsche owners with cheramic brakes that suffer from fading brakes...

    Practical example, my father bought a BMW M5 in -99 when they appeared, as I have been racing quite a bit I arranged for him to drive at Mantorp park, a racetrack.
    He´s not a bad driver at all, but after about 5 or 6 laps he came into the pits with NO brakes at all, the pedal went without any resistance straight to the floor, better feel in the clutch! He had left the ESP or DTC on...
    I immediatelly took the car out, running two slow laps without touching the brakes, had ESP turned off, felt that the brakes were back and gunned it!
    It was a BMW event so the place was buzzing with more or less modded Beemers, most running on tracktyres, some even on slicks. the only one to keep up with me was a M5 e34 (mid -90s) on slicks, M3s with track tires was passed with ease, and most importantly, no brake issues!

    If you managed my bad spelling so far I must empashize that you should ALLWAYS stay within your comfort zone, especially on the road!!!
    If you´re at the track and still wants it on, leave it on and dont listen to racenuts from the other side of the pond.

    Just my 2 cents!

    When the boys (and I know of one girl) streetrace in Stockholm the audience (ie friends and interested) tend to block the road for a few seconds so that the drivers aren´t concerned with more than the race itself.
    I have seen the police abandoning their car due to blocking vehicles and running up to the start, beeing just 10 meters behind the racers when they sets off, and they keept running!!! LMAO!
    Try to outrun a 9 second car if you can...

    Is there any (illegal) streetracing going on in the US anymore?
    I know you have (what it seems like to me) a drag strip on every corner, ok, town at least.
    In the Stockholm area we have the "Birka cup", I think 6 different events, all at night on different locations around town, outside the town, they´re not screaming past the nightclubs doing 9 sec 1/4... Limitations are lights, and no more than 10.5" wheels.
    Then we have Stockholm open, one race a year, you have to drive the whole time, no trailerqueens, putting your car on a trailer means you´re out!
    Other than that, you can bring a Pro Mod!
    That will get you in trouble with the law though...

    Fredrik;)

    I'm sure there is "organized" street racing going on. We don't condone it and we don't discuss it on this forum.

    Yes, but the thing on your dash doesn't mean slippery when wet. It's a picture of what your burnout will look like.

    That's how we roll on the C...If you ask a question here, i promise it will get answered, and if Dave (Quick) is involved, he'll explain the astro physics, of the breakdown to the molecular structure of it also. :)

    so all SRT's have the full off feature? I've just touched the button and the car leaves some rubber on the ground. Never knew that holding it down would shut it off completely

    Your's definitely does. Not sure about the late model ones but I think they do too? Car has to be sitting still or in park or less than 10 mph or something like that. In park will definitely work. Press and hold the button for about 5 seconds or so and you'll get a different symbol and a chime. The difference between one touch and full off is that you will be able to leave rubber going sideways as well. One touch is full off for straight line burnouts.

    Plus you get a message in the Evic stating "ESP Disabled".
