Launch Control - What am i doing Wrong?

[Seanay]

Hi all. I have a 16 GT manual i bought used with 24k miles on it. Tried to use the launch control other day and it would not work or engage. Im hoping someone here has insight into what Im doing wrong. I follow all the directions, set the launch RPM to 3K, put in sport mode, hold down the clutch and press the gas all the way to the floor waiting for the RPM icon to show up on the bottom of the gauge next to the LC icon...

Here's where it goes wrong. when my RPM gets to just before 3k, it feels like it just stops responding but the RPM light icon does not come on so Im not sure if it is engaged or not and its suppose to go limp at 3k like that or something is just cutting my fuel as the throttle becomes useless at that point with no input response whatsoever. Am I suppose to just pop the clutch at 3k regardless of whether the RPM light icon comes on? I dont know if it makes a difference but I have the Ford Racing Power pack 2 installed with the tune so i dont know if that has anything to do with it.

I don't recall any light or anything when I had my manual car. But if it's holding rpm at 3,000 or whatever you set it to it's working. From there just let out the clutch and it will do it's thing. Also note you CANNOT turn off the ABS or stability control or it won't work.

Hi Jay
I was referring to the video that Ford made for LC, Line Lock, features all over youtube. They say a light icon "RPM" should light up next to your LC icon once engaged after holding down throttle to engage LC but I do not see it and it does not hold at 3k so Im guessing its not engaged. If I let go of the throttle, the RPM drops back down and I dont think that is normal. Hoping someone could chime in and advise if its user error or there is a malfunction of some sort....the directions are pretty simple and clear so I dont know what if any, im doing wrong.

Letting off the gas - the RPM's will drop. The main thing launch control does is hold RPM's to a certain RPM (The one you set) even with your foot on the floor.

In your thread starting post, you said it held at 3K RPM and it didn't go higher, that's normal behavior. You also said when you got off the gas, it dropped back down to idle, that's correct.

LC engages, revs to the RPM you've set it to and sits there with your foot mashing the gas pedal to the floor, then you dump the clutch and the car should do the rest.

What are you expecting to have happen?

Thanks. I see. I thought it was not working because i expected the RPM to hold at the user set RPM even with my foot off the gas. Did Ford get rid of the RPM light icon that they show in their instructional vids? It never comes on

My bad. Thought the LC would hold the revs at the set range RPM even if i let off the gas, i will correct that. Thanks for clearing it up. Still expecting the little light to come on but it never does, threw me off. But you are right it makes sense I could hold gas to floor cuz it does not rev higher then set RPM then let out the clutch.

The manual says to DISengage traction control. This is utterly false.

As soon as you select the 'checkbox' for RPM you'll see the 'RPM' light. It's the screen prior to setting the RPM itself.
Clutch in, shift to first, floor it and the RPMs should go to wherever you set them. If you keep your foot floored and the RPMs drop on their own (to like 1500) and then zoom back up to the preset, only to chop the RPMs back, repeat you do NOT have the mode engaged. I don't know why it even has such a behavioral mode. If it's doing that, toggle traction control back on.

Assuming your RPMs are steady, theoretically you can basically just dump the clutch (let go of pedal) but that's going to put tremendous force thru the driveline and I wouldn't do it. You can, however ease out the clutch a lot faster than you otherwise might while keeping the throttle pinned and you'll get moving!

If you don't have the differential fixes in your car, I would do that first. The $29 bolt kit is the minimum I would do since it has the slop reduction spacers in it.

imagine how many would be plowing into crowds and the woods if they allowed it

Only requirement should be car dead stopped and clutch fully in. You have to commit to the gas pedal too. It will slowly rev over the set rpm limit if your gentle applying the gas.

Dump the clutch... traction control does the rest.

Quite fun once you get the hang of it. Fool proof launching

What happened to the rpm light that's supposed to come on as seen on the Ford instructional video? I can't get a straight answer from Ford chat

No clue on the light. If you try not to dump the clutch, it may take a few tries. I was feathering it at first but it disengages the LC then. So I dumped it a few times and likely wont again for a long while.

You seem way more obsessed about this light than you should be.

You work for Ford as a customer experience rep? You sound like them, got nothing useful to add move along troll.

Question: What stops the car from moving if 1 foot is on the clutch and the other is on the gas?
