Hey all,

I believe I am having an issue with my launch control settings.

Everything functions with launch control as it should. What I am unsure of it that the RPM settings give me a range of 3100-4500 rpms. Is this correct?

This seems to be on the opposite end of the spectrum as even at 3100 rpms I still just sit and spin. There would be no hope to hook up at 4500 rpms, this seems entirely too high to even be an option.

I cannot find literature to confirm what the settings should actually have available, but from the research I have done, the range is typically below the 3100 rpm threshold.

My car is a 2018 Challenger T/A 392 with 2,500 miles.

Automatic transmission? My 16 A8 starts at I think 1500 and goes up in 250 rpm increments. Most I can use is 2000 rpm or too much wheelspin.

I have the 6-speed manual transmission.

I feel like the RPM range is flip flopped on my car. 3100 as a minimum gives me entirely too much wheelspin. And I can't even imagine someone setting it to 4500 rpms.

Yeah no way on the 4500 rpm lol. Honestly I haven't messed with the M6 launch control much but I know you must dump the clutch with the accelerator to the floor, otherwise it will not work. Find an rpm at which you can do this without bog or too much spin. The traction control will handle much of the excess spin but not all so keep it floored and let it do it's thing.

It functions 100%. I can activate it, and it spins the tires for the first 60 feet before hooking up. That's at the lowest adjustment it gives me as an option. (3100 rpm)

Granted this isn't on a prepped surface, just hot asphalt. But there would be no logical improvement to utilize any part of the range above 3100 rpm.

What I don't understand is the videos of the 2017 models and earlier demonstrating launch control between 1800 and 2500 rpm. I don't even have that option, and cannot find anyone with another 2018 to compare.

I'd like to take the car to the track but this is also something I want figured out before I do so.

The auto has lower rpm settings, think 1500 is the lowest. Highest I can go now with these worn out all seasons is 2000 and they still spin a good bit.

60 feet sounds like too much spin. It's in Sport Mode or not?

The car has always been in sport mode when I've tried using launch control. I have not tried without being in sport mode, but I don't see that being different.

I feel like you would want the RPM set even lower in sport mode than non-sport/ comfort. Unless it's a bug or something. None of the dealership models have enough milage to test, and I do not know anyone personally with a 2018 T/A to see what their settings look like.

I have not turned traction control all of the way off yet to see if that makes a difference in the settings.

Welcome to Challengertalk Cashdollar2009. Are you saying the actual display shows lower number 3100 and upper number 4500?


@steve37887 has a M6 and has used launch control (earlier model, but unlikely it has changed), perhaps he can say what the rpm range on his is

Hey thanks! I'm hoping to become a contributing member as I read through the forums and get to know my car.

The screen displays the entire RPM range, but limits me to selecting between 3100 and 4500 rpm with the slider.

I will take a picture tomorrow to upload. My question is that I believe 3100 RPM is too high, let alone sliding it all of the way up to 4500 rpm.

The videos that I have watch gave the option to launch all of the way down around 1500 to 3000 rpm, which makes much more sense to me. I am wondering if this may be an issue with the firmware or something. The service department at my dealership told me to post on some forums because he had no idea.

All the videos I've seen are automatics, except one manual Charger, but he had his set at 3250, so I am unsure...3100 and above seems useless, you almost assuredly would spin

I think you're right, everything I've seen has been an automatic. I just had to get the 6-speed... Lol

At 3100 I spin entirely too much. My 0-60 times (not the best) have been 7.2 seconds with launch control and 6.0 seconds manually releasing the clutch at a lower rpm.

You'll need to work on that, I get a 5.9 on my V6 :) Hopefully steve37887 will see this thread, and let us know what range his has.

Welcome to the group. I looked at mine this morning and my rpm range is 2500-4500. Seems odd that it's 3100 as the lowest for you, if they would have changed something for the T/A I would have thought a more even # like 3,000 or something. But yea something definitely seems off there. One other thing, you can't turn traction control all the way off and use launch control. Most you can do is put traction in sport mode. The system uses TC to control the wheel spin so it won't even activate if you have it all the way off. I haven't had a chance yet to try turning it off through my tuner and seeing if it will activate or not but I suspect that result will be the same too. I hope to try that out this weekend.

So here's a picture of my actual setting screen for launch control.

It's currently set to 3100 rpm which is my lower limit, and can adjust up to 4500 rpm.

There are no numbers specified in the owners manual and I cannot find numbers published online for what it should be. The dealership has no knowledge of what they should be.

Found an article from 2015 stating the manual should have a range from 2,000 - 4,500 rpm.

15 Things You Didn?t Know About Dodge?s Performance Pages - Hot Rod Network

"What You Didn’t Know:
The launch rpm limits are selectable, but will vary between the automatic transmission (1,500–3,500 rpm) and manual transmission (2,000-4,500 rpm). Also, Launch Control is only available after 500 miles of driving. To set rpm, just touch and drag the rpm bar to the desired level."

Interesting since neither yours nor mine go that low

Also, I had some numbers mixed up.

With launch control really is 7.2 seconds with bad wheel spin. Without launch control is 5.1 seconds. ?

Update...

My dealership contacted "The SRT Team" yesterday and they said whatever the vehicle is pre-programmed at is correct and it cannot be changed with new firmware.

So in the 2018 6-Speed the rpm range is limited to 3100 - 4500 RPM and cannot be adjusted any lower. The range for the Automatic Transmission is supposed to be lower.

The solution I was given was to look into drag radials.

To be fair, I have not tried launching the vehicle at a track with a prepared surface, or drag radials. I've only ever had stock tires and hot Texas asphalt.

I've not had much success with launch control on my A8 2016 Scat Pack with Goodyear F1 tires. Excessive tire spin and smoke regardless of launch RPM. Can't imagine dumping the clutch at 3100, don't think it would stop spinning until you run out of gas. Drag radials make a huge difference but even then they need to be heated correctly or they will spin as well.
