It doesn't after the revision. It absolutely did on the first run of GTRs. They had the launch rpm too high.

Whoops. Quoted wrong Boob post :rofl2:

Was it only if it broke something?

We launch controlled my buddies '09 (well he did, not me, I was just a passenger) a few times.

Not sure if he ever had to take it in for warranty work, but they never denied him any other service or informed him that the warranty was voided for use of it.

Was that the first year of the GTR? I thought it was 08. It depends on which revision of launch control it had. Once they reflashed it you could do it to your hearts content. It was the original LC map that was way too aggressive and would cause warranty issues if you broke something doing it.

I have a feeling that Ford won't be denying all warranty claims based on using the line lock. Probably just motor/tranny issues.

2009 was the USMY. JDM MY's are off from ours typically. theirs is more literal vs USMY being the year ahead kind of thing. like how our 2015 cars will be out in 2014.

the original 2 versions of the GTR tranny ECU controls would basically lock down the car if you tried to run launch control too many times and in too quick of sucession without the proper cool down period allowed.

Yeah, they had to take a few swings at lauch control before it wouldn't grenade the tranny. They let buyers beta test that one. Now it seems like it's solid as long as you don't go too nuts.

yea after the 3rd or 4th change to the tranny tuning it seemed to be better. now the launch control is great and can be used more than ever. think the original was like 5 strikes and youre out lol send it in to be replaced lol

Pretty much. After the first few times you used it it was time for a new first gear IIRC. And it was easy for them to claim "abuse" and stick you with the repair even though it never should have been able to cause itself to break.

yea first few versions werent perfect but still awesome.

some local guy had a 2009 right when they came out and blew the engine. nissan actually flew a few of the engine builders out to the US to evaluate it since it should have never happened.

Too awesome. That was the problem. It's always fastest right before it explodes. :rofl2:

thats usually the case with myself.........i mean. :wtf2:

:nutswinger:

I heard that also voids the warranty.

"Line Lock is essentially the Mustang GT's mating call, the way it shows dominance over other, lesser pony cars."

update.....

Use The 2015 Mustang's Burnout Control To Race, Lose Your Warranty

What do you mean the Z does not have line lock?
