Launch Control

[Craigga542]

Do these 18+ have any built in launch control in sport mode or is there a way to enter it via hidden controls like other Ford vehicles? Referencing a full launch control or software based brake torquing, compared to manually doing it.

No Ford SUV’s have Launch control.

Basically best launch is gained by Sport Mode, 4A, ELSD On, Traction Control Off. No need to turn AdvanceTrac off, it does not factor in to going straight.

Stand on the brake, push RPMs up to about 2800-2900, and hold for a sec(You can put boost up on Gauge Cluster to make sure you have built some up), full throttle, release brake. 2 footing on these things works best.

Stock tune fights you on the RPMs, but tuned, not a problem.

Got this on my Limited SE Max 4x4 with 22’s using the technique above.



This was a ZFG 93 Tune in “Drag” Mode.

^^This. Tried it a few times and it's pretty exhilarating for a big SUV. Left foot on the brake, right foot on the skinny pedal. The brakes start to let go a little below 3K.

Two thoughts. First, didn’t the stock one run 6 sec? I would have thought the tune would have taken off slightly more than that. Second, really curious if there’s a discernible difference between tow vs non-tow gearing.

What app is that, or is it the tuner?

I don’t base my times off numbers gotten from journalists on a track. That is perfect world. Mine is a the worst combo for good 0-60 from a weight, and unsprung weight. Limited, Long, with 22’s.

6.4 was my 0-60 stock with 93 in the tank. So that is almost a second off of factory with just a 93 tune. Impressive for this weight vehicle.

4x4 helps with traction, but adds weight. And I do have the Heavy Tow package. So 3.73’s, that helps with the launch.

The app is Dragy, it is not just an app, it talks to a VERY accurate little GPS device. It is just as accurate as being at a Track, the “apps” that others use, are not, because they use the phones GPS or the cars speedometer via OBDII. Both are inherently inaccurate.

How much does .9 seconds cost?

$700. There is no other Mod that will net you EVEN close to those results for that price.

I think Ford uses an open rear diff on the Expy. Maybe a limited slip , definitely not a posi. It doesn't make enough power to spin the wheels off a start. It's designed to tow. Launch control is for Mustang, Hellcat or Trackhawk, bud.

 

[sanman28]

Lol....i wouldnt worry about burnouts or traction issues. Not enough power and too much weight to do anything on dry pavement. Just do a boosted launch and enjoy what you have.

 

[LokiWolf]

HAHAHAHA.... You aren't doing it right. If you leave Traction Control on, no it won't spin tires because it is pulling power because it senses wheel spin. If you turn Traction control off even Stock I can spin the back wheels. Engage the ELSD Lock Mode, and I can spin BOTH back wheels launching with Boost, on a Stock Tune with TC off. Need to be in 4A or 4H to not spin even with the Stock tuning.

I repeat, if you don't think it has enough power stock to spin the wheels, you are doing it wrong.

@rjdelp7 Here is a video to educate you again...It has way more than a limited slip.

Don’t think you can lock the rear with the navigator unless you’re in 4 wheel mode right?

Not sure. The Expeditions get a button.

Only the 4wd’s get the button. I wish the 2wd’s had the button.

That's not for high performance. It's for slippery roads and snow. Plenty of videos on youtube of mustang, line lock burn outs, launch control and traction control. You need to watch and learn about what real high performance is.

Don’t think anyone is saying the expy is a performance vehicle. Only that it DOES have a locking rear diff and if you want to you can easily smoke tires.

'easily smoke the tires?' I don't think so.

Yeah but you also thought they didn’t have a locker. So...

Line Lock? That is parlor trick to do burn outs. Original reason for them was to put heat in the tires before making a run. Now it is so people can do burnouts with out skill.

It is actually easier to launch an Expedition vs a Mustang(Without launch control), because of additional weight and 4 wheel drive.

I know EXACTLY what high performance is. Have you actually ever been on an actual track, say Watkins Glenn, Road America, LimeRock, Summit Point, VIR, Roebling Road, Sebring, Daytona? I have. Drove some seriously fast cars on them. I don’t need to watch videos.

Traction control in most cases is in direct opposition to fast times, both in a straight line and on a road course.

Only an idiot 'launches' an Expedition or compares it to racing a Mustang. Another pathetic argument.
