Actually NO.
I had these extensions on my '11 SES.
I removed the spoiler before trade in and put it on the ST.

I know. By the way, I drove my SES for the first time in three months today and still love that too.

Wow, launch control too. Very interesting indeed.

I've been waiting to post details until I could get some video, but I got launch control about a month ago with my custom tune from Innovative Tuning in Buffalo. He gave me several tunes with different launch RPMs. Using even the lowest one (3k) it launches well but as soon as the boost comes on both front tires just roast ... especially the stockers. I was able to get reasonable launches with the Direzzas, but still had to feather the throttle to keep the spin to a minimum before I grab 2nd gear. I bet with real R compound tires it would be just right.

I had to lower the limiter to 2400 to prevent spinning the stock front tires.

Ok I am at a bit of a loss now. I had Innovative make me tunes with 2400 and 2700 launch limits. Today I tried the 2400 tune and still smoked both front tires when the boost came on. Do I have that much more power than you? Unfortunately I don't think there are a lot of other data points on this yet.

The launch control cuts out at the preset speed (default is 4.8 MPH). It's designed to get you off the line. Once the boost comes on, you're way past that speed and launch control won't help you. You can set a higher speed, but that would probably not be a good thing. At some point, you will need to moderate the throttle to avoid excessive wheel spin. That's a big part of the torque limiting that Ford put in our ECU. The AP tunes bypass that and the tradeoff is that we can now spin the tires quite readily.

Ok I do understand how the launch control works, but I thought you were saying you could launch and hold the pedal on the floor through first gear without excessive wheelspin

Sure. Just set the cutoff speed to 30 and you won't spin the tires at all in first.Ok I do understand how the launch control works, but I thought you were saying you could launch and hold the pedal on the floor through first gear without excessive wheelspin
I think that might make the car a bit less fun overall though. Sorry If I made it sound like it was like that. Probably better to leave TC on or at least Sport mode and let that control wheel spin.141 - 157 of 157 Posts
