Hey Folks,

I'm having a heckuva time with the launch control feature on my 2013 SRT Challenger. I purchased it used last year with about 3300 miles on it and have not tried the LC feature until about a week ago. I did searches on here and the internet about how to do it as I couldn't find a single piece of documentation from the manufacturer on in in the manuals.

Anyway, I stop the car on reasonably level ground, push the TC button twice and it tells me in the EVIC that it has entered the Launch Mode. I've tried setting different RPM levels but every time I push in the clutch and then depress the throttle the RPMs just spin freely and are not held at any particular level. In other words, I can redline it if I want to. Then when I let out the clutch there's some slipping of the wheels and the EVIC immediately disables the LC. I've tried at all different RPM levels, sometimes as low as 2500 and just can't get the thing to work. I'm thinking maybe the car needs a flash update? It's supposed to hold the engine RPM at the level that's set in the EVIC even if you floor the gas, right?

Yes, whatever how it works with the manual, before you launch you should be able to keep the RPM at whatever setting you have it set for ever.

I have an auto so it holds it at 1800. If I keep both feet on each pedal (gas and brake), I can hold the car at 1800 for hours.

From what I read you cannot even get it to the point where it holds it at your RPM setting, i'm sure a 6 speed guy will jump in. Note that even at 1800 in an automatic, the tires are spinning and it is useless on normal tires. You need really good tires for that thing to help your times.

Yes, it doesn't hold the RPM level like it should.

It sounds like I may have a traction problem as well. I have the original factory tires on there but still am getting a significant amount of wheel slip.

How quickly are you depressing the gas pedal? If you do it slowly, it doesn't stick at the proper RPM for some reason. You almost need to plant your foot to the floor in an instant. For me anyway...

Okay, I'll try that.

1.) Make sure you are on a completely level surface and the car is not rolling
2.) Depress clutch
3.) Put in 1st gear
4.) Press button twice
5.) Depress gas FAST (peg it to the floor within 1 second or less)
6.) Drop clutch and hang on!

Thanks for the input guys. I finally got it to work. It seems like it was a combo of not depressing the accelerator quickly enough and sometimes not being on flat enough ground.

Just read my own post and hustled to delete the nonsensical content.
